Air humidity in the apartment: how to measure it and tips on how to change it. How to measure air humidity in an apartment: methods and devices How to find out what kind of air is in an apartment

How to determine the humidity in the apartment

What device measures humidity and where to buy such a meter? If the air in your apartment is too humid or, on the contrary, dry, then you need to take some measures to establish its optimal level. But first, you should familiarize yourself with how to determine and how to measure air humidity at home. There are several ways to measure air humidity.

Hygrometer

Using this device is the simplest and most correct option.

When choosing a hygrometer, you should pay attention to its accuracy. Measurement deviation should be no more than 1%

Glass beaker

This method is not accurate, but if necessary, it will help you understand the moisture values. The necessary items for the implementation of such a task are probably in the arsenal of every housewife.

Procedure:

Fill a glass jar with cold water.
Refrigerate the contents of the glass to 3-5 degrees.
Place the vessel in the room away from heating appliances and analyze the result.

Result evaluation:

The walls of the vessel were fogged up, but after about 10 minutes they became dry. This result indicates an extremely low humidity level.
The misted walls of the glass did not dry out even after 5-10 minutes and the drops flow into the glass. Such indicators indicate high humidity.
The condensation formed on the walls of the glass container did not evaporate, but it also does not drain off in large drops. This effect indicates that the moisture in the air is within normal limits.

Procedure:

First, you need to measure the air temperature with a standard mercury thermometer. Record your readings.
Wrap the head of the device with damp wet cotton wool or gauze and after 10 minutes evaluate the thermometer readings.
Subtract the wet bulb reading from the dry bulb temperature.
Find the resulting difference by the values of a special Assman psychometric table, determining the level of humidity in the room you need.

Moisture measurement methods

The indicator of a comfortable indoor climate is called relative humidity. This parameter is calculated based on the vapor content and its interaction with the air.

Relative humidity is measured in several ways:

visually and by the senses of those who are regularly in the room;
using special equipment;
using alternative methods.

Let's take a closer look at how you can measure indoor humidity and what it takes.

Hardware measurement of relative air humidity

Hygrometers are considered to be the most accurate and demanded devices for measuring humidity.

A hygrometer is a device designed for high-precision measurement of air humidity and is subdivided into several subtypes.

For the most accurate measurement of the relative humidity in a room, only high-quality and high-precision instruments should be used. Electronic hygrometers are considered one of the most accurate devices.

The most classic options for such devices are: hair, film and psychometric hygrometers.

Option number 1 - hair hygrometer

This type of hygrometer is based on synthetic hair, a measuring scale with an arrow and a spring.When the readings fluctuate with respect to moisture, the tension force of the hair changes, which causes the spring to operate and display the measured data on a scale.

Such a device can measure readings ranging from 30% to 80%.

Option number 2 - film type hygrometer

Such a device consists of a sensitive film and a counterweight that react to changes in dryness or humidity. Indicators are displayed on a scale and, as in the previous case, range from 30% to 80%.

Option number 3 - psychometric device

Hygrometer of psychometric type. This device works on the principle of interaction of two thermometers (dry and wet). The readings that are displayed on the scale of the thermometers must be checked against a special table and the exact data on the humidity in the room must be calculated.

This type of devices is of three types: remote, station, aspiration. The most popular is the station hygrometer.

A psychometric hygrometer is a fairly simple, but nevertheless, quite accurate device. Therefore, some users prefer these particular devices.

Option number 4 - laboratory devices

Such devices belong to the category of professional hygrometers used exclusively in laboratory conditions. This subtype of measuring instruments includes mechanical weighing and condensing apparatuses.

Their application requires special skills and knowledge, therefore such hygrometers are not used for home humidity measurement.

Option number 5 - electronic hygrometers

These devices are digital instruments for measuring indoor climate. They are compact, easy to use and do not require any special skills from the owner.

Digital hygrometers are equipped with a special sensor and can operate both from the mains and from the battery charge, depending on the model and its cost.

A digital hygrometer is not only a device that accurately determines the level of humidity in a room. It fits perfectly into the interior, and also combines the functions of a thermometer and a clock

Multifunctional digital hygrometers are often advertised by manufacturers as weather stations. These devices not only allow you to monitor indoor humidity readings, but also have a modern design and an amazing combination of options.

Alternative moisture measurement methods

Alternative methods should not be 100% trusted, however, their readings can be a reason to buy professional measuring equipment.

In addition to special equipment, there are alternative methods, however, such techniques are not among the most effective. They are only able to indicate deviations in the relative humidity of the room.

So how is the relative humidity in a room measured if a hygrometer is not at hand?

Method number 1 - a glass of water

In order to apply this method in action, you need to take ordinary tap water into a glass and cool it in a refrigerator to a temperature of no more than +5 ° C. Then, take the glass out of the refrigerator, leave it in the room for 10 minutes and evaluate the results of the experiment.

If condensation has formed on the surface and walls of the glass removed from the freezer, this indicates an excessively humid microclimate in the room.

If the glass dries up after 10 minutes, you can draw conclusions about too dry air. The optimal result is the presence of condensation, which does not dry out, but does not run off in large drops.

This testifies to the normal humidity of the air environment, which is comfortable for humans.

Method number 2 - using a mercury thermometer

This method is based on a principle similar to that of a psychometric hygrometer.In order to measure the humidity of the room, it is necessary to measure the air temperature with an ordinary mercury thermometer and record the indicators.

Then, wrap the thermometer head with a thick cotton cloth or gauze soaked in water and re-measure the room temperature. To obtain accurate indicators, you need to calculate the difference between the first and second measurements and calculate the result using a special table.

The results of the above two methods for determining humidity cannot be called reliable, therefore, to obtain accurate indicators, it is recommended to use professional or home hygrometers.

Folk ways to measure indoor moisture

The importance of humidity in the house has been known for a long time. We learned to determine deviations from the norm, even when measuring instruments did not exist

People watched the houseplants. If the flowers dry, despite frequent watering, then this indicates dry air in the room. The increased water content led to decay.

The condition of the soil in a flower pot will quickly indicate moisture levels.

Observation of nature suggested another way of determining. It has been noticed that the spruce cone shrinks its scales when the moisture in the air rises. And vice versa, it fully reveals itself when it lacks water. If you attach a pine cone to plywood and hang it in a room, it will warn you about changes in water content in the atmosphere.

Attention to detail and using the experience of ancestors will help determine the degree of humidity in the house without household appliances. An ordinary glass cup with water must be kept in the refrigerator for at least five hours.

Then it is installed on the table and after 5 minutes its walls will show the state of humidity in the room. If they just fogged up, then everything is fine. Running trickles will indicate an increased condition. Dry - about a serious shortage

If they just fogged up, then everything is fine. Running trickles will indicate an increased condition. Dry - about a serious shortage.

You don't have to buy a psychrometer, but measure the readings with one room thermometer. To do this, you need to write down the readings on paper and wrap the thermometer with a damp cotton swab. Take readings after 10 minutes. How to make calculations was mentioned above. But you can use the Asman table.

Conclusions and useful video on the topic

How to measure the humidity in a room with a glass of water:

As you can see, a good measuring device is only half the battle, the most important thing is to take timely measures to restore the microclimate in the room and regularly monitor changes in the hygrometer indicators.

Do you measure the humidity in your own home? What methods or devices do you use to do this? Please share your own experience with our readers. Leave your comments in the block below.

Danger of dry air

The problem of dry air is especially relevant during the hot season, when the ambient temperature rises significantly. This leads to the fact that dust, pollen, animal hair and other allergens can easily move around rooms and do not settle on furniture. Thus, it is easier for them to enter the human body through the respiratory tract and cause a serious reaction. This is especially dangerous for young children.

In addition, dry air causes the mucous membranes of the respiratory tract to dry out, which makes the organs vulnerable to the action of microbes. It is difficult to work in a room with dry air, even for a very efficient person, as the body gets tired quickly. A person constantly experiences a feeling of drowsiness.Increased static electricity is also common in these areas.

How air humidity affects the condition of apartment residents

The accumulation of moisture on the windows is the first sign of high humidity.

Condensation on windows and mold indicates excessive moisture in the room. Fungal mold can cause many diseases, including:

bronchitis;
the development of oncological diseases;
asthma;
otitis media (ear inflammation);
allergic reactions;
diseases of the cardiovascular system.

If the listed diseases began to develop in family members, you must immediately figure out how to check the humidity in the apartment. All residents of the house may suffer from immunodeficiency and persistent headaches.

Important: mold in the home can cause diathesis in babies, provoked by low immunity

Dry air is just as dangerous as excessively humid air. Particles of water contribute to the deposition of various allergens such as dust, pet hair and others. In dry air, allergens float freely around the room, thereby entering the body. Residents of such a room are accompanied by chronic fatigue, infectious diseases develop faster. Children may develop renal failure and dysbiosis.

The first signs of a change in the microclimate

Any deviations in relative humidity can be called an uncomfortable microclimate. Too dry air, as well as excessively humid air, is harmful to human health, interior items, furniture and all living things.

The primary methods for determining fluctuations in humidity and dryness are:

unpleasant sensations on the mucous membranes, dryness of the skin unusual for humans, the appearance of a cough, frequent colds or allergic reactions;
the formation of condensation on windows, mirrors and other glass surfaces;
the occurrence of mold, dampness;
wilting of plants;
change in the appearance of furniture (drying, swelling of varnished products, etc.).

Any of these changes can be caused by too dry or humid air.

Pay attention to the first signs of high humidity or dryness - they become an important reason to start measuring indicators.

Withering of plants on the windowsill, even despite frequent watering, is an accurate sign of too dry indoor air.

In order to most accurately measure the relative humidity and take any measures to balance this indicator, special instruments should be used.

Increased moisture

Measurement of air humidity in the apartment is made so as not to face the difficulties of air dryness and increased moisture level. Some people think that this is not a particularly serious problem, so installing a hygrometer is pointless. But this attitude must be changed, since there will be negative consequences if the humidity level in the apartment is not controlled.

The relatively high level of moisture in the air at home is a source of microscopic fungi on surfaces. Also, such conditions are a favorable environment for the development of a fungus, which can adversely affect human health. Mold can lead to the development of allergies in a person.

But remember that allergies are just one of the diseases that mold can cause in humans. The fungus can become the source of a variety of infectious diseases.

Mold spores can end up in your food. A person and his entire body can begin to suffer from foodborne diseases. It is dangerous for all people who live in this house.

To avoid all these problems, it is necessary to regularly ventilate the room. Airing should take place regardless of the temperature outside the window and at any time of the year.

You will be able to enjoy a pleasant home environment due to the fact that the moisture is always normal.

Due to the fact that you will control the level of humidity in the room, it will help eliminate the possibility of mold or mildew on different surfaces. It will also keep your body healthy. Therefore, a hygrometer was created that will make your task easier. The stores have a fairly wide range of these devices, which allows you to choose the right hygrometer just for yourself.

When selecting, look at the accuracy of the machine's values. Not everyone needs devices (meters) that display ultra-accurate readings of the level of relative humidity. Most buyers are satisfied with the approximate values when determining. Air humidity in the room and the accuracy of the readings depend on the technical component of the meter.

First, compare the technical characteristics of each type of moisture detector. A device that is randomly chosen will cause a lot of frustration during use, and will not meet all the requirements. You will only spoil your nerves and mood and waste your money.

Therefore, after purchasing the qualifier, save the receipt for it, so as not to face future troubles. Thanks to the check, the hygrometer can be returned back to the store if it does not meet your requirements. Buy a quality identifier to protect your room! You will be able to maintain home coziness and comfort.

The climate of our country presupposes the almost constant use of heating devices, which greatly contribute to an increase in the dryness of the air, and the optimal humidity in the apartment becomes an unattainable dream.

Nonetheless, the microclimate of the home plays a critical role in ensuring the health of the people living in it. In the case when the level of moisture content does not reach the prescribed values, each person, be it an adult or a child, will certainly encounter a number of unpleasant phenomena.

Humidity and babies

Children are the most important thing in any full-fledged family.

Particular attention should be paid to the quality of their living conditions. Air temperature and humidity are the most important parameters for them, directly affecting their health.

Any deviations can immediately affect their general condition, and modern doctors today put the humidity in the room and the constant flow of fresh air to the fore in relation to the health of every child.

Deviations from the norm of humidity can cause respiratory diseases - Photo 11

Air humidification for children's health - Photo 12

Providing comfortable conditions for the respiratory system, we strengthen the child's immunity, and in case of illness, maintaining the necessary air parameters will make the healing process much more rapid and can allow avoiding the medication part of the treatment.

Childhood is the stage at which our baby is not only vulnerable to external factors. At this stage, the formation of his health takes place, which largely determines the further quality of his life.

How to measure the humidity in the apartment

The well-known humidity rate of 55-60% must be confirmed by special devices.

In stores there is an apparatus called a hygrometer, which allows you to accurately set the humidity readings. Several varieties of these devices can be noted:

hairy;
weight;
electrolytic;
condensing;
ceramic;
weight;
film.

Among the rich variety, everyone can choose the technique that will not hit the pocket and will accurately determine the necessary indicators

When choosing moisture measuring instruments, you should pay attention to their technical characteristics. Typically, the standard is a range of twenty to ninety units.

Before starting observations, measure the error of the apparatus, which can vary from one to five values of the scale.

It is worth noting that if it is supposed to measure indicators in rooms with a high level of moisture in the air, it would be best to prefer a device that has a high degree of protection against moisture penetration and condensation.

Air humidity meter

Thermohygrometer

is a very complex device that measures not only the humidity of the air, but also the temperature in the room. Among other things, the thermo-hygrometer records readings about the state of temperature and humidity, recorded from different points. That is, directly from the place where the thermohygrometer itself is installed and from the point where the sensor was previously installed.

The device synchronizes the readings obtained from different points in the room, and based on this, it already provides the results of checking the humidity level and measuring the temperature.

A few words can be said about the technical characteristics of the thermohygrometer. The cable of this device has a length of one and a half meters, and the indicators are displayed in the range from 0 to 90%. There is also wireless models

thermohygrometers. These devices are equipped with another useful function, which is that in case of a critical state of humidity in the room, an alarm is triggered, notifying of an unfavorable change in the state of the air.

Tips for creating a comfortable microclimate

Follow the tips for regulating indoor humidity and be confident in the comfort and health of your household

If the humidity in the room is low, you should regularly ventilate the room, perform wet cleaning at least 2-3 times a week, or purchase a special device for humidifying the air.

Instead of a humidifier, you can use climatic equipment with a built-in humidification and ionization function.

In rooms where the humidity is higher than normal, it is necessary to avoid drying clothes in the room and ensure high-quality ventilation of the room. Remember to use the air dryer regularly.

Careful measurement and control of the relative humidity in any room is the key to the health and well-being of humans, plants, animals and the durability of furniture and other structures that can lose their appearance due to excessive humidity or dryness of the air environment.

Measuring device

Today there are several types of household appliance for measuring air humidity in rooms or apartments. How is the humidity in the rooms measured and determined? Let's take a closer look at all types of hygrometers.

Thermohygrometer

Air humidity can be measured using a thermo-hygrometer. Consider his work. It has a complex system, so it determines not only the level of moisture, but also the value of the temperature inside the room. Also, in addition, this device records the values of the state of moisture and temperature values at various points. That is, he compares the state of two indicators in the place where he is at this moment and in the previous room.

The device for determining the humidity of the air synchronizes the values that it received at various points in the building. According to these readings, the thermo-hygrometer gives an overall result of the humidity and temperature values. What technical characteristics does it have?

Consider the technical characteristics of the thermohygrometer. The wire is 150 centimeters long. Readings are shown as percentages, ranging from 0 to 90. You can also purchase thermo-hygrometers that are cordless in stores.

These models have an additional function: when the state of the moisture level in the room is critical, the measuring device gives a signal that notifies the owner of the bad air situation. It is convenient to use this device (s) or meter when measuring the humidity in the apartment.

With this hygrometer you can measure temperature and humidity. You will literally participate in changing the home "weather".

Psychrometer

This room unit is fully called a psychrometric hygrometer. How to determine air humidity in an apartment using a psychrometer? They have two thermometers. One thermometer is called "dry", which does the standard job of measuring the temperature in a room.

Another thermometer is a wet one, because it is inside a water container and is wrapped in a cloth wick. It gives indications of the temperature of the wick that is wet. The value of this temperature is obtained by evaporation of moisture. If the moisture indicator is low, then evaporation is much faster. And vice versa.

Thanks to the psychrometer, you can get the necessary information about the state of your room, that is, determine the humidity of the air. Today, a psychrometer is often used to control moisture content.

Devices: hair and film

A hair instrument for measuring indoor air humidity is fairly easy to set up. Why is it called that? The operation of this type of hygrometer is carried out on the basis of synthetic hair, which is fat-free. How to find out the humidity of the air on it? How to measure air humidity in an apartment using a hair device?

From a change in the state of the air, this synthetic fat-free hair also changes its length. It is stretched between the spring and the arrow end. Due to the oscillation of synthetic hair, the arrow moves along the plate with divisions (dial), which gives the general values of the moisture level in the room. Let's discuss the "insides" of the apparatus.

This device for measuring air humidity has a wide range of values - from 0 to 100. Therefore, information about the state of the air flow will be the most accurate. Its main feature is the simplicity of its work. They are easy to handle, so you won't have to worry about using it. This meter can be placed on the wall in the room - it is quite convenient. Measure and find out the data about the condition of the apartment, which will always be in front of your eyes.

There is another type of hygrometer - a film hygrometer. How to check the humidity in the apartment using it? A film hygrometer is composed differently, therefore, the principle of operation differs from a hair hygrometer. The main distinguishing feature of a film hygrometer is the presence of an element that is sensitive. This component in the device is an organic film. The principle of operation - the organic film can stretch, or vice versa, shrink - it depends on the state of humidity in the house. The humidity value is also displayed on the dial.

If there are relatively low temperatures in a certain humid room, then it is recommended to use hair or film hygrometers. Other devices are simply not suitable for determining the level of humidity in a room, they are practically not used.

How to increase air humidity

Knowing how to check the humidity in the apartment, you will see, albeit not an accurate, but an approximate picture of the real situation. Thanks to this, you can take the following steps to saturate it with moisture.

Humidifier

As a rule, such devices are designed to work in rooms up to 150 square meters. The principle of its operation is as follows: water is poured into a special tank to a certain level. When the humidifier is in operation, the water evaporates and saturates the air with its molecules.

There are three types of humidifiers.

Traditional type

A mechanical humidifier fulfills its mission with a built-in fan. It drives air through a special container with water, as a result of which the air is cleaned of dust and saturated with moisture.

Steam type

A similar appliance works in the same way as a kettle. The water boils and comes out in the form of steam. Some models have special nozzles for inhalation. Thus, the device can be used not only to increase air humidity, but also to treat the respiratory tract.

Disadvantages:

Hot steam, the temperature of which reaches 60 degrees, can lead, if safety rules are not followed, damage to human skin and the surface of nearby objects.
High noise level during operation.
Power consumption is quite high.

Ultrasonic type

Such a device, thanks to a built-in special membrane, turns water into steam. It is less noisy than mechanical and steam humidifiers. The water heating function contributes to the effective fight against microbes in the air.

Works only with distilled water or with special purification cartridges to purify and soften liquids. The latter should be changed regularly.

Folk ways to increase humidity

In the absence of a humidifier, you can use simple folk methods not only to determine the humidity in the room at home, but also to correct the situation.

In this case, the following measures are suitable:

The easiest way is to place a wet towel or sheet on top of the radiator. When the fabric heats up, water will begin to evaporate from the fabric. After the towel has dried, it should be wetted again.
An analogue of the first method is placing containers with water on heating devices. It will be necessary to add water to the inside of the container every few days.
You can place a container of water on pieces of furniture, such as a closet. With this method, the water does not evaporate as quickly as on the battery, but still, the humidity rises.

For the next method, you will need a bowl of water and a bandage. Having put a cup of water near the battery, one end of the bandage should be placed in water, and the other should be fixed to the heating element. The water will constantly rise along the threads of the bandage and evaporate into the air with the help of the heat emanating from the battery.
If the air is too dry, drying the washed laundry in the room can humidify it.
The presence of a large number of indoor plants has a beneficial effect on the normalization of the air humidity level.
Leave the bathroom door open after you shower. Thus, you get rid of excess moisture in the bathroom and saturate the air of other rooms with it.

What signs in the apartment will tell about high or low humidity

Various little things will help determine the humidity in the apartment.

You just need to pay attention

p, blockquote 25,0,0,0,0 ->

Condensation on the windows will be the first to talk about the increased water content in the air. Everything in the house will become damp and the furniture will give off a woody smell. Then the sense of smell will begin to distinguish notes of putrefaction and decomposition, a specific smell of mustiness will appear.

Under such conditions, mold and fungus will quickly begin to develop, infecting households with various diseases.

If children develop diathesis, then this may be the reason for the high moisture content in the air. Asthma attacks, coughs and headaches can confirm this. If you do not take action, you can get more serious diseases. Such as otitis media, bronchitis and decreased immune defenses.

Cancer cells multiply faster in high humidity.

The state of the human body also changes with a lack of moisture. People get tired faster, fall into drowsiness, excessive sweating occurs. This leads to drying out of all the mucous membranes of the body, which can have serious consequences.

p, blockquote 28,0,0,0,0 ->

If dust hanging in the air is clearly visible in the room, then the humidity level has dropped significantly. The air is dry and the particles (under the weight of water) do not settle on objects, but are easily drawn into the lungs. Aggravation of allergic reactions is confirmation of this.

The importance of moisture in human life is undeniably proven. Therefore, it will be prudent to constantly monitor its norm.

To do this, you can use both purchased measuring instruments and use the experience of ancestors. Paying attention to everyday little things will help you understand that abnormalities have occurred. This will quickly fix the situation and bring everything back to normal.

The well-being and health of its owners depends on the state of the microclimate in the apartment. The level of humidity is one of the main indicators characterizing the parameters of the air that people in the room breathe. Therefore, it should be monitored periodically. This indicator should remain at the level established by sanitary and hygienic standards.

Therefore, the tenants of the house are faced with the question of how to determine the humidity in the apartment. For this, various methods are used. Even without special devices, everyone can measure the level of humidity in a room. The existing methods will be discussed in detail below.

Permissible value

Studying the question of how you can determine the humidity in the apartment, you should consider the permissible values of this indicator. It should be noted that moisture is measured as a percentage. This is the fraction of the primary mass volume of moisture.

Experts say that the optimal value of the indicator for a room is 45%. In this case, its deviation in both directions is allowed. Thus, the humidity in the apartment should not exceed the range from 30 to 60%.

There are standards that determine the parameters of the air, depending on the purpose of the room. In the living room or dining room, the range is 45-60%, and for the bedroom of adults, it is 40-50%. The humidity should be higher in the nursery. Normally, it is at the level of 45-60%.

But for a library or office, it is important to maintain this indicator at the level of 30-40%. This will save documents, books from premature destruction. In a kitchen or bathroom, humidity can be between 40 and 60%.

How to maintain the relative humidity in your home

We have already decided how to measure the state of air humidity in the room, it remains now to figure out how to restore the optimal humidity level.

If the humidity is low

Ventilate the room.

However, this method can not always significantly improve the state of the home microclimate, since in summer the outside air can be dry.

Also, when airing in the traditional way, dangerous microbes, allergens, dust, harmful gases and unpleasant odors can get into the apartment. But if you keep the windows constantly closed, then there is a high probability of encountering another problem of maintaining the microclimate - stuffiness (high levels of carbon dioxide).

Good ventilation is also important when ventilating rooms. A valve can provide fresh air to the room, but it will not be enough to ventilate a room where more than one person lives. The air passing through the supply and exhaust valve is not heated or cleaned.

A breather will help you to easily deal with the stuffiness and not let dangerous "guests" from the street into the house. This is a supply ventilation device that takes air from the street, heats it up, cleans it and delivers it into the room.

Damp mop regularly

rooms.

Set up an aquarium at home.

Keeping fish at home in the aquarium can also affect the humidity in the air. But remember to look after your fish and keep your aquarium clean. Can be placed on windowsills or near heating radiators
containers with water
.

Humidifier

- a good option for the home. This device will cope with the dryness of the home air, improve the microclimate and prevent the development of respiratory diseases.

Climatic equipment (air conditioner, breather, air purifier, Danfoss Eco thermostat)

complete with the MagicAir base station will help not only to track the data of the microclimate in the house, but also to maintain optimal performance.

The base station collects information from room air about temperature, humidity and carbon dioxide concentration. All indicators are displayed on the smartphone screen in the MagicAir application.

If the humidity is high

The second side of the coin is too much moisture in the air.

Do not dry laundry in the apartment.
The best place to do this is on the balcony.
After taking water procedures, when the humidity in the bathroom can reach 100%, need to ventilate
... With good ventilation, it will be enough to open the bathroom door and the window closest to the bathroom, or turn on the breather.
You can purchase a special moisture absorption device
... The principle of operation of this device is the opposite of the process of air humidification: a built-in fan drives humid air through the device. An evaporator is also located inside, which converts moisture into condensate, which flows down into a special container.

If you make the habit of constantly maintaining optimal air humidity at the required level, this will help reduce the risk of developing respiratory diseases and cases of allergic reactions. Normalized moisture has a beneficial effect on the skin, protects it from drying out and premature aging.

How to reduce indoor humidity

If the humidity level in the apartment is higher than normal, you can purchase a special device - an air dehumidifier. It drives humid air through an “evaporator” where the temperature difference (the temperature in the device is lower than in the room) converts the moisture into condensation. Drops of condensate drain into a special container.

The air heats up again and enters the room. Thus, excess moisture disappears from the room. When buying a dehumidifier, the main focus is on its performance, which is calculated in “liters per day”.

A household dehumidifier can absorb 12 to 300 liters of water in 24 hours. Dehumidifiers are portable and stationary. Portable can be used in different rooms. Stationary ones are wall-mounted and cannot be moved. At the same time, they have greater productivity.

The advantage of dehumidifiers is their ability to function in cold rooms, since the frost generated during operation is removed automatically. If the water tank is filled and if it is untimely empty, the device turns off without the participation of the owner.

In a small room, you can lower the humidity by using moisture absorbers. The device includes a special tablet that adsorbs water from the air.

It is designed for an average area of 20 m². The disadvantage of the scavenger is that the tablet needs to be changed frequently. The advantage is the absence of noise, compactness and price. The moisture absorber is especially suitable for those who have seasonal moisture.

Folk remedies for lowering humidity

Among the folk remedies, the simplest is regular airing. The more often it is carried out, the drier the air will become. Even if the humidity outside is higher than home humidity, it decreases when the apartment is ventilated. Bathroom and toilet are unventilated rooms.

Hoods are provided for air circulation in them. However, they do not always cope with the volume of work. Therefore, it is not superfluous to install an exhaust fan.

An oil cooler with a built-in fan will dry humid air in a small room. The installed air conditioner will maintain the required temperature and humidity level.

The sun's rays can dry the air well through uncurtained windows in the rooms.The kitchen can also be equipped with extraction systems. They not only help in the fight against moisture, but also remove unwanted odors.

Feeling comfortable at home is very important for any person. High-quality air in the apartment has a positive effect on the well-being of residents, helps to avoid chronic diseases and allergic reactions to dust or mold. Therefore, it is very important to determine the level of humidity in the house, and then to maintain it.

What are the consequences of exceeding the norm of humidity in the room?

An excess of water can also be dangerous to humans, so many people wonder what air humidity is considered normal in an apartment and how to keep climatic conditions within this indicator. The increased content of water vapor in the room becomes an excellent breeding ground for fungi, mold and harmful bacteria.

The frequency and severity of respiratory diseases increases - diseases such as bronchitis, runny nose, allergies and asthma become chronic and difficult to treat.
The microclimate in the rooms becomes unacceptable for life - people feel dampness or stuffiness in the rooms.
The feeling of freshness is lost - the discharge of multiplying pathogenic organisms causes the appearance of unpleasant odors.
The drying time of the washed laundry will increase.

An increased indicator of air humidity in an apartment is also harmful to the environment. Plants begin to rot, mold appears on the ceiling and walls, and wooden surfaces undergo deformation changes. Books and other paper products change their structure.

The level of humidity in the apartment where the child lives is a very significant indicator. The state of health of the baby and the peace of mind of his relatives depend on him.

The fact is that the child's body goes through the thermoregulation procedure in a special way, so dry air can negatively affect it. The air that a baby breathes out has one hundred percent humidity and body temperature. If the humidity of the surrounding space is low, the child will have to waste a lot of internal fluid to humidify the air. Loss of water by a child's body can lead to unpleasant consequences that are best avoided. The more humidified the air, the less money we will spend on medicines. This is the rule that should be taken as a basis.

In order to maintain this level, any of the following methods can be applied:

regular wet cleaning;
the presence of an aquarium;
wet towels on batteries or bowls of water in the room;
modern humidifiers.

Maintaining the necessary humidity in a children's room is not at all a difficult task, and the presence of undeniable advantages makes every parent strive to achieve it.

The level of humidity in the apartment is normal

The air we breathe is always filled to some extent with water vapor (we, of course, do not take into account desert regions that are not suitable for human life). Air humidity indicates the content of these vapors. It can be absolute and relative.

If we measure the volume of water in a cubic meter of air, we know its absolute humidity. Let's imagine that we took one cubic meter of air and found 13 g of water in it. This 13 g / m3 is its absolute humidity.

But if we want to calculate the relative humidity of the air, then we need to know two quantities: the maximum possible volume of water in a cubic meter of air (it depends on the temperature: the higher it is, the more moisture the air can hold) and the real volume of water in a given cubic meter of air.

The percentage of the actual volume to the maximum possible will be the relative humidity of the air. For example, a cubic meter of air with a temperature of 24 ° C can hold a maximum of 21.8 g of water.If we found 13 g of water in it, then its relative humidity is about 60%.

What is the norm of humidity in the apartment indicated in official sources? Building standards for Russia are spelled out in the interstate GOST 30494-96 “Residential and public buildings. Indoor microclimate parameters ".

According to this document, the optimal relative humidity in the cold season is 30-45%, and in the warm - 30-60%. The limit values are also specified in GOST: in winter, according to the authors, it should not exceed 60%, and in summer - 65%.

It is worth remembering that the figures indicated by GOST are intended primarily not for residents of buildings, but for those who design and maintain these buildings.

This can be seen, for example, by the fact that the GOST standard for humidity in an apartment is lower in winter than in summer. This is due to the fact that during the cold season, the relative humidity of the outdoor air drops significantly when it warms up to room temperature.

It is difficult to design and maintain a building so that it can maintain “summer” humidity standards in winter without significant costs. But this does not mean that the human body needs less moisture in winter.

Physiologists recommend maintaining the humidity in the apartment at 40-60% regardless of the season.

How much humidity should be in the room? 30% humidity - the lower limit of the norm according to GOST - is felt by many as dry air with all the attendant consequences. This moisture is also insufficient for most indoor plants: they will begin to dry out and wither. The optimum humidity for indoor flowers common in our latitudes is 40-70%.

The norm of air humidity in the apartment in winter

radiator heating;
additional heating devices;
restriction in the flow of fresh air due to closed or sealed plastic windows.

All these factors affect not only the comfortable humidity in the apartment, but can also become an invisible source of health problems.

Allowable indoor humidity indicators are limited by the quantitative values specified in the SanPiN. During inspections, measurements are carried out in accordance with GOST methods. The permissible values for housing located in different climatic zones are different, the required standards are not the same at different times of the year.

What percentage of humidity should be in the apartment?
The sanitary standards regulate the maximum relative humidity allowed in living rooms, which is 65% in summer and 60% in the cold season.
Physiologists pay attention to the need to control the minimum indicators, which at any time of the year should not be less than 40%. It is believed that the ideal parameters for living rooms should be between 40% and 60%.

In winter, when heating a room, whether it be a private house or an apartment, the humidity can drop sharply due to the dryness of the air. This should be monitored, if necessary, turning on the humidifier, opening the window for ventilation or installing trays with water.

In the winter season, any living space is heated. In the northern regions of the country, it is especially intense due to severe frosts. Heat from radiators or underfloor heating dries up the air. This can be defined quite simply - drying out of the nasal and nasopharyngeal mucosa, especially after sleep.

It is these factors that lead not only to discomfort, but also to an increased risk of acute respiratory infections. In a dream, we are more vulnerable, so it is best to humidify the air at night or in the evening.

The optimal temperature for a full stay is + 18 ... + 24 ° C. Normal air humidity in the apartment should be 45-30%. The maximum allowable is 60%.

Air humidity in the apartment is the norm for the child

A child's body is worse than an adult in coping with harmful environmental factors. Children freeze faster and overheat faster, catch colds easily, catch infections more often and suffer more diseases.

Therefore, the microclimate in the nursery should help maintain the protective forces of the child's body, and humidity plays an important role here. The air should never be dry. In dry air, the child's body intensively loses moisture.

The mucous membranes of the nasopharynx dry out and lose the ability to resist infections, the baby may feel itchy eyes, and peeling may appear on sensitive skin.

The norm of humidity in an apartment for a child is 50-60%.

The well-known children's doctor Yevgeny Komarovsky insists on more: he calls 60% humidity the norm for a healthy child and recommends 70% for a baby who has an infection (the higher the humidity, the less the mucous membranes dry out).

Important! Exceeding 24 ° C in the nursery can lead to overheating of the baby's body. As a result, the drying of the mucous membranes and the loss of fluid will accelerate.

The humidity rate for a child in winter does not differ from summer. But there is an important point: in both winter and summer, it is advisable to keep the temperature in the children's room at a level not higher than 24 ° C. If the room is warmer, then 60% humidity will turn the nursery into the tropics.

You probably know from your own experience that high humidity is much more difficult to tolerate in heat than in cold weather. In addition, exceeding the specified temperature norm can cause overheating of the child's body, which will, again, lead to loss of fluids, drying out of the mucous membranes and skin.

Comfortable indoor humidity for humans

The optimal level of air humidity is one of the components that provide comfortable climatic conditions for human living. Moreover, each of the premises, depending on its purpose, has its own microclimate.

Most often, people care about the temperature and quality of air masses in the house, forgetting about this indicator. But it is the number of water molecules (steam) in the air that affects the perception of temperature by the human body, the safety of the indoor environment and the condition of plants.

Many people think that air humidity is an almost imperceptible indicator in the house, but this is not so. Surely many have seen the formation of condensation on the glass in the cold season. It is this condensate that is the excess moisture in the air.

It tends to condense where objects are as cold as possible. That is why we see droplets on the windows.

The generally accepted average indicator of normal air humidity in an apartment should be 45%. It can vary depending on the type of premises and its operating conditions.

A deviation from the norm is possible both in the winter season and in the warm season. In both cases, a lack or excess of moisture entails a deterioration in human health, the condition of plants and damage to furniture, decoration, etc.

What should be the humidity in the apartment?

Optimal parameters of humidity and temperature for individual rooms:

Premises	Air temperature, ° C	Air humidity, %
Bedroom	16-20	40-55
Children	18-24	50-60
Living room	18-23	40-50
Kitchen	19-22	40-50
Bathroom	21-23	40-50
Restroom	16-19	40-45
Study	18-22	30-40
Hallway	18-19	40-45
Greenhouse	16-25	50-70

Rooms such as the kitchen, bathroom and toilet will always have an increased level of moisture, so the standard for these rooms is higher than for other rooms.

Deviations from normal humidity have negative consequences. So, the low liquid content in the air leads to a lot of were indoors. This is harmful not only from an aesthetic point of view, but also due to the negative impact on health, especially for those with allergies. Dry and dusty air can cause serious illness!

In addition, excessive dryness is fraught with the skin and mucous membranes.If the comfortable air humidity is exceeded, a person will feel uncomfortable, furniture and antiques will be stored much worse than with a normal liquid content in the room.

And also excessively humid air will become a real haven for all kinds of bacteria, including disease-causing ones. It causes the appearance of fungus and mold, dampness.

for people: 40-70%;
for plants: 50-75%;
for books, equipment, furniture: 40-60%.
