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 vice versa - 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 the humidity of the air at home. There are several ways to measure air humidity.
Hygrometer
Using this device is the easiest and surest option.
When choosing a hygrometer, you should pay attention to its accuracy. Measurement deviation should be no more than 1%
glass cup
This method is not accurate, but if necessary, it will help to understand the values \u200b\u200bof humidity. The necessary items for the implementation of such a task are probably in the arsenal of every housewife.
Procedure:
- Fill a glass vessel with cold water.
- Cool the contents of the glass to 3-5 degrees.
- Place the vessel in the room away from heating devices, and analyze the result.
Result evaluation:
- The walls of the vessel were fogged up, but after about 10 minutes they were dry. This result indicates an extremely low level of humidity.
- The misted walls of the glass have not dried up even after 5-10 minutes and the drops flow into the glass. Such indicators indicate high humidity.
- The condensate formed on the walls of the glass container has not evaporated, but it does not flow down in large drops either. This effect indicates that the moisture in the air is within the normal range.
Procedure:
- First you need to measure the air temperature using 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 from the dry-bulb temperature number the wet-bulb reading number.
- Find the resulting difference according to the values of the special Assmann psychometric table, determining the level of air humidity in the room you need.
Folk ways to measure the humidity in the room
The importance of humidity in the home has long been known. Deviations from the norm have learned to determine even when measuring instruments did not exist
People followed indoor plants. If the flowers dry, despite frequent watering, then this indicates the dryness of the air in the room. The increased water content led to rotting.
The condition of the soil in the flower pot will quickly indicate the level of humidity.
Observation of nature suggested another way of determining. It is noticed that the spruce cone compresses its scales with increasing moisture in the air. And vice versa, it fully opens when there is not enough water for it. If you attach a cone to plywood and hang it in a room, it will warn you about changes in the water content in the atmosphere.
Attention to detail and the use of the experience of ancestors will help determine the degree of humidity in the house and without household appliances. An ordinary glass glass of water should 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 sweat, then everything is fine. Running streams will tell you about an elevated state. Dry - about a serious shortage

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 sweat, then everything is fine. Running streams will tell you about an elevated state. Dry - about a serious shortage.
You can not buy a psychrometer, but measure the readings with one room thermometer.To do this, write down the readings on paper and wrap the thermometer with a damp cotton swab. Take readings after 10 minutes. How to make calculations, mentioned above. But you can use the Azman table.
Danger of dry air
The problem of dry air is especially relevant in the hot season, when the ambient temperature rises significantly. This leads tothat dust, plant pollen, animal hair and other allergens easily move around the rooms and do not settle on pieces of 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 small children.
In addition, dry air causes the mucous membranes of the respiratory tract to dry out, making 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 quickly gets tired. A person constantly experiences a feeling of drowsiness. Increased static electricity is also a characteristic phenomenon in such rooms.
How air humidity affects the condition of the inhabitants of the apartment
The accumulation of moisture on the windows is the first sign of high humidity.
Condensation on windows and mold indicate excessive levels of moisture in the room. Fungal mold can cause many diseases, including:
- bronchitis;
- the development of cancer;
- 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 can suffer from immunodeficiency and constant headaches.
Important: mold in the house can cause diathesis in infants, provoked by low immunity
Dry air is no less dangerous than excessively humid air. Water particles contribute to the settling of various allergens such as dust, pet hair and others. In dry air, allergens freely float around the room, thereby entering the body. Residents of such premises are accompanied by chronic fatigue, infectious diseases develop faster. Children may develop kidney failure and dysbacteriosis.
Increased moisture
The measurement of air humidity in the apartment is carried out so as not to encounter the difficulties of dry air and an increased level of moisture. Some believe that this is not a particularly serious problem, so installing a hygrometer is pointless. But we need to change this attitude, as 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 the source of the appearance of microscopic fungi on surfaces. Also, such conditions are a favorable environment for the development of fungus, which can adversely affect human health. Mold can lead to the development of allergies in humans.
But do not forget that allergies are just one of the diseases that can cause mold in a person. The fungus can become a source of various infectious diseases.
Mold spores can end up in your food. A person and his entire body can begin to suffer from foodborne diseases. This is dangerous for all the people who live in this house.
To avoid all these problems, it is necessary to regularly ventilate the room. Ventilation should take place regardless of the temperature outside the window and at any time of the year.
You will be able to enjoy favorable home conditions due to the fact that the moisture will always be normal.
Due to the fact that you will control the level of humidity in the room, it will help to eliminate the likelihood of mold or mildew on different surfaces. It will also keep your body healthy. Therefore, a hygrometer was created, which will facilitate your task.The stores have a fairly wide range of these devices, which allows you to choose the right hygrometer for yourself.
During selection, look at the accuracy of the apparatus values. Not everyone needs devices (meters) that display ultra-precise readings of the level of relative humidity. Most buyers are satisfied with the approximate values \u200b\u200bin determining. The humidity in the room and the accuracy of the readings depend on the technical component of the meter.
First, compare the specifications of each type of moisture meter. A device that is randomly selected will cause a lot of dissatisfaction during use, and will not meet all requirements. You will only spoil your nerves and mood and spend your money for nothing.
Therefore, after buying a determinant, keep a receipt for it so as not to run into future troubles. Thanks to the receipt, the hygrometer can be returned to the store if it does not meet your requirements. Buy a quality identifier to protect the room! You will be able to maintain home coziness and comfort.
The climate of our country involves the almost constant use of heating devices, which greatly contribute to the increase in dryness of the air, and the optimal humidity in the apartment becomes an unattainable dream.
Nevertheless, the microclimate of the dwelling plays a crucial 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, whether an adult or a child, will certainly face a number of unpleasant phenomena.
How to measure the humidity in the apartment
The well-known humidity norm of 55–60% must be confirmed by special devices.
In stores there is a device called a hygrometer, which allows you to accurately determine the humidity. There are several types of these devices:
- hair;
- weight;
- electrolytic;
- condensation;
- 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 humidity measuring instruments, you should pay attention to their technical characteristics. As a rule, the standard range is from twenty to ninety units.
Before starting observations, measure the error of the device, which can vary from one to five scale values.
It is worth noting that if it is planned 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 its penetration and condensation.
Device for determining air humidity
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 thermohygrometer captures readings on 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 received from different points in the room, and on the basis of 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%. Also have wireless models
thermohygrometers. These devices are equipped with another useful feature, which consists in the fact 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.
measuring device
Today there are several types of household device for measuring air humidity in rooms or apartments. How is air humidity measured in rooms and determined? Let's take a closer look at all types of hygrometers.
Thermohygrometer
Air humidity can be measured with a thermohygrometer. Let's take a look at his work. It has a complex system, so it determines not only the level of moisture, but also the temperature value inside the room. Also, in addition, this apparatus records the values of the state of moisture and the temperature value 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 thermohygrometer gives a total result of the humidity and temperature values. What technical characteristics does it have?
Consider the technical characteristics of the thermohygrometer. The length of the wire is 150 centimeters. The readings are displayed as percentages, the range of which is from 0 to 90. You can also purchase models of thermo-hygrometers that are wireless in stores.
These models have an additional function: when the condition of the moisture level in the room is critical, the measuring device gives a signal that notifies the owner of a bad air situation. It is convenient to use this device (devices) or a meter, 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 apparatus is fully called a psychrometric hygrometer. How to determine the humidity in the apartment using a psychrometer? They have two thermometers. One thermometer is called "dry", which performs a standard job - measuring the temperature in the room.
The other thermometer is humid because it is inside a water vessel and is wrapped in a cloth wick. It gives an indication of the temperature of the wick, which is wet. The value of this temperature is obtained by evaporation of moisture. If the humidity indicator is low, then evaporation is carried out 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 monitor moisture content.
Devices: hair and film
The hair device for measuring the humidity of the air in the room is quite easily arranged. Why is it called that? The work of this type of hygrometer is carried out on the basis of synthetic hair, which is defatted. How to find out the humidity of the air on it? How to measure the humidity in the apartment thanks to the 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 switch end. Due to the oscillation of the 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 device.
This air humidity meter has a large range of values from 0 to 100. Therefore, the 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 struggle with them while using them. This meter can be placed on the wall in the room - it's quite convenient. Measure and find out the data on the condition of the apartment, which will always be in front of your eyes.
There is another type of hygrometer - this is a film hygrometer.How to check the humidity in the apartment with it? The film hygrometer is different, therefore, the principle of operation is different from the 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 a hair or film hygrometer. Other devices are simply not suitable for determining the level of humidity in the 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 approximate picture of the real situation. Thanks to this, you can take the following measures 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. During operation of the humidifier, water evaporates and saturates the air with its molecules.
There are three types of humidifiers.
traditional type
The mechanical humidifier fulfills its mission with the 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 device works in the same way as a kettle. The water boils and comes out as 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.
Flaws:
- Hot steam, the temperature of which reaches 60 degrees, can lead, if safety rules are not followed, to damage human skin and the surface of nearby objects.
- High noise level during operation.
- Fairly high power consumption.
ultrasonic type
Such a device, thanks to the built-in special membrane, turns water into steam. It is less noisy than mechanical and steam humidifiers. The presence of the function of heating water contributes to the effective fight against microbes in the air.
Works only with distilled water or with special cleaning cartridges to clean and soften the liquid. 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 the radiator. When the fabric is heated, the water from it will begin to evaporate. After drying the towel, it should be wetted again.
- An analogue of the first method is the placement of water containers on heating devices. It will be necessary to add water inside the tank every few days.
- You can arrange a container of water on pieces of furniture, such as a closet. With this method, water does not evaporate as quickly as on a battery, but still, the humidity rises.
- For the next method, you will need a bowl of water and a bandage. Having placed a cup of water near the battery, one end of the bandage should be placed in water, and the other should be fixed on the heating element. The water will constantly rise up the threads of the bandage and evaporate into the air with the help of the heat coming from the battery.
- If the air is too dry, drying your laundry indoors can moisten it.
- The presence of a large number of indoor plants has a beneficial effect on the normalization of the level of humidity in the air.
- Leave the bathroom door open after showering. Thus, you will get rid of excess moisture in the bathroom and saturate the air of other rooms with it.
What signs in the apartment will tell you 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. All things in the house will become damp, and the furniture will begin to emit the smell of wood. Then the sense of smell will begin to distinguish notes of decay and decomposition, a specific musty smell will appear.
Under such conditions, mold and fungus will quickly begin to develop, infecting households with various diseases.
If children have diathesis, this may be the reason for the high moisture content in the air. Asthma attacks, coughing 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, and excessive sweating occurs. This leads to the drying 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 level of humidity has dropped significantly. The air is too dry and particles (under the weight of water) do not settle on objects, but are easily drawn into the lungs. Exacerbation of allergic reactions is confirmation of this.
The importance of humidity in human life has been undeniably proven. Therefore, it would be wise 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 deviations have occurred. This will quickly correct 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 breathe in the room. Therefore, it must be periodically monitored. This indicator should remain at the level established by sanitary and hygienic standards.
Therefore, the residents of the house face the question of how to determine the humidity in the apartment. Various methods are used for this. Even without special devices, everyone can measure the level of humidity in the room. Existing methods will be discussed in detail below.
How to Maintain Relative Humidity at Home
We have already decided how to measure the state of humidity in the room, it remains now to figure out how to restore the optimal level of humidity.
If the humidity is low
Ventilate the room. However, this method cannot always significantly improve the state of the home microclimate, since in summer the outdoor air can be dry.
Also, when airing in the traditional way, dangerous microbes, allergens, dust, harmful gases and unpleasant odors can enter 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).
High-quality ventilation is also important when airing rooms. A valve can provide fresh air to the room, but it will not be enough to ventilate a room in which more than one person lives. The air passing through the supply and exhaust valve is not heated and is not cleaned.
A breather will help you easily deal with 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, purifies it and supplies it to the room.
Wet clean regularly rooms.
Set up an aquarium at home. Keeping fish in an aquarium at home can also affect the humidity of the air. But remember that you need to take care of the fish and keep the aquarium clean.
Can be placed on window sills or near radiators containers with water.
Humidifier - a good option for the home. This device will cope with the dryness of 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, it will help not only track the data on the state of the microclimate in the house, but also 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 other side of the coin is too much moisture in the air.
- Do not dry clothes in the apartment. The best thing to do is on the balcony.
- After taking water procedures, when the humidity in the bathroom can reach up to 100%, need to ventilate. With high-quality ventilation, it will be enough to open the door to the bathroom and the window closest to the bathroom or turn on the breather.
- You can buy special moisture absorption device. The principle of operation of this device is opposite to the process of air humidification: a built-in fan drives humid air through the device. An evaporator is also located inside, which turns moisture into condensate, which flows into a special container.
If you make a 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 favorably affects the skin, protects it from drying out and premature aging.
Optimum air humidity in the apartment for a child
The level of humidity in the apartment in which the child lives is a very significant indicator. The state of health of the baby and the peace of his relatives depend on him.
The fact is that the child's body undergoes a thermoregulation procedure in a special way, so dry air can adversely affect it. The air that a baby exhales has 100% humidity and body temperature. If the humidity of the surrounding space is low, the child will have to spend a lot of internal fluid to humidify the air. The loss of water in 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 to follow.
To maintain this level, any of the following methods can be used:
- 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 the children's room is not at all a difficult task, and the presence of undeniable advantages makes every parent strive to achieve it.
Calculation methods for determining moisture
Having received the readings of the aspiration psychrometer, it is necessary to calculate first the absolute humidity, then the relative readings. They are used for domestic purposes.
p, blockquote 17,0,0,0,0 —>
Absolute indication formula: A = F1 - a (t1 - t2) P.
p, blockquote 18,0,0,0,0 —>
- A - humidity (absolute);
- F1 - saturation and elasticity of water vapor at wet bulb readings;
- a is the psychrometry coefficient (it is affected by the air flow rate supplied by the fan);
- (t1 - t2) - temperature difference between dry (t1) and wet (t2) thermometer;
- P - air pressure (determined by a barometer).
p, blockquote 19,0,0,0,0 —>
After calculating the absolute values, a relative indicator is found. To do this, the absolute amount found is divided by the saturation and elasticity of water vapor, taking the readings of a dry thermometer. Then the result obtained must be multiplied by 100. This will be the relative indicator of air humidity.
