Do you need a humidifier in kindergarten. Pleasant microclimate, health and comfort - air humidifier for children: which one is better? Main categories and characteristics of models

According to modern sanitary standards, relative humidity in preschool institutions should not be lower than 40-60%. In practice, in winter, in groups, humidity often does not exceed 25%, which is comparable to dry air in the Sahara Desert. In Russia, the heating season lasts for half a year, which means that all this time children in kindergartens are forced to breathe insufficiently humidified air, because the higher the temperature in the rooms, the drier the air.

Experts say that dry air is dangerous and can cause considerable harm to children's health. The fact is that the mucous membranes of the respiratory tract of a child are in daily contact with a huge number of pathogens. However, not always a meeting with the causative agent of the disease leads to the development of infection. Mucous membranes are able to trap and destroy bacteria at the site of their introduction - this is how local immunity manifests itself.

What happens to the body of a child who is forced to spend a lot of time in a dry microclimate? Insufficiently humid air leads to drying of the mucous membranes, and, therefore, to a violation of local immunity. Dried mucus is an ideal breeding ground for microorganisms, and, therefore, the cause of bronchitis, sinusitis and otitis media.

In addition, under the influence of dry air, the susceptibility of the mucous membranes to allergens and dust increases, and the child's risk of developing allergic pathology increases - up to asthma.

Excessively dry air kindergarten dries out delicate baby skin, thereby not only creating discomfort for the baby, but also reducing its natural protective properties.

Compared to adults, young children are more in need of the right microclimate, because due to a more intensive metabolism, the child's body produces more heat. A dry atmosphere contributes to increased sweating and loss of fluid from breathing, which, in turn, leads to thickening of the blood and even disruption of the kidneys.

If we take these factors into account, it becomes clear that a humidifier in a kindergarten today is not a luxury, but a reasonable concern for the health of children. Experts do not recommend installing steam humidifiers, but ultrasonic devices will be the best option for DDU.

To date ultrasonic humidifiers are considered the most effective and safe. Their action is based on the following mechanism: water from the tank is supplied to a plate that vibrates with high speed, where it splits into small splashes. Tiny droplets form a cloud through which the fan drives the surrounding air. In other words, an ultrasonic humidifier generates mist at home. The device works almost silently and is safe for both children and adults.

Good afternoon, today the parent committee offered to buy a humidifier for the kindergarten. All were accepted with a bang. What worries me is how safe this device is. I am afraid that this will lead to an increase in diseases of the lungs and bronchi. After all, children will breathe all this air after humidifying the rooms, and in the water it may not be known how many microbes, salts, and some other impurities. In addition, they want to buy this humidifier for the entire kindergarten, which means transferring it from group to group, and I'm afraid this will lead to even more viruses in the water, which children will then get with moisture. On the Internet I found not only positive but negative feedback from using these devices, for example: - you are right about bacteria and impurities in the air from the humidifier. Salts, from the mist of the humidifier bonds, penetrate into all the cracks. They also accumulate in the lungs, and when you stop using the humidifier, they irritate and dry the mucous membranes for some time. There are already plenty of bacteria in the poured water. Most of them are relatively harmless iron bacteria, but there are enough dangerous pneumobacteria. Duty officer, bacteria are different, and far from always they will smell when the device is operating. Oz humidifiers cannot be cleaned sufficiently, especially the tank, and any cleaning of them is a very inconvenient task that can ruin them. The mucus from the tank cannot be completely cleaned, no matter how hard you try. Dezavid in the bonds of the humidifier can not be poured. - My friend had a humidifier, they actively used it, her daughter began to have attacks of obstructive bronchitis, after 2-3 attacks the humidifier was removed, there was no more obstruction ... I, too, am somewhat afraid of washing and a humidifier, maybe well, nafig excess humidity ... Ventilate more often, since our city is small, the environment allows ... - A couple of weeks after buying an air washer and installing it in the nursery, the child began to have yellow snot. Then green. Then with blood. Then 38.8, some kind of infection, we are treated with antibiotics. My husband has bronchitis and antibiotics. I am 37 weeks old, I have a cough, what to treat - I don’t know yet, I’m calling the doctor tomorrow. So I’m sinning on a humidifier, we didn’t have such health problems before it! My husband didn’t get sick at all like this - we began to sleep better with a humidifier, but then we coughed right away (((and a day later the snot went very strongly and immediately green ... So I’m thinking of linking it together or just a coincidence. And a lot of similar reviews. The most worrying thing is that this idea was voiced by a mother whose son coughs in the kindergarten until he vomits and loses his breath ... But she proudly declares that they have this device at home and the son breathes normally at home, so it’s the fault of coughing in the kindergarten "This is the absence of this device. But looking at her son, I have doubts, because no one else in the group coughs like that, and in general, other children almost do not cough. I ask you to clarify whether it is possible to use this device in kindergarten or I'm not afraid for nothing purchase of this machine?. Thank you in advance -- Thank you for your attention.

Special points to consider when choosing purifiers and humidifiers for child care facilities.

What you need to know about air and cleaning devices when choosing equipment for child care facilities?

• Air disinfection devices are mandatory for installation only in medical offices. The installation of air purifiers in kindergarten groups is recommended by sanitary doctors, but is not mandatory. Therefore, most often, their purchase is carried out by parents.
• Devices must have certificates of conformity. Registration certificates for products medical technology are optional when installing appliances in bedrooms and playrooms.
• When choosing an air purifier, it must be taken into account that a large number of children in one room complicates the task of air disinfection. Choose devices with a large margin of performance.
• The rate of spread of infection and the severity of the disease depend on the number of viruses that have entered the human body and the readiness of the immune system to resist pathogens.
• Air purification devices can reduce the concentration of pathogenic microflora in the room atmosphere by several times. These devices have long been used in healthcare settings and significantly reduce the risk of transmission of infections. But there are no devices that can 100% clean the air from viruses and bacteria in a room where people are.
• During epidemics, air disinfection devices can significantly reduce the likelihood of the spread of the disease, but it is equally important to ensure a healthy atmosphere in rooms where children stay for a long time throughout the year. This will enhance the body's defenses. Viruses attack everyone, but not everyone gets sick, and those who get sick carry the disease in different ways.
• Dirty air of the streets of the city and especially the premises weakens the immune system. Clean air enhances.
• Rospotrebnadzor determined the following parameters of the air environment for preschool children's organizations. (SAHPIN 2.4.1.3049-13) The air temperature in the game room is not lower than 21 C. In the bedroom, it is not lower than 19 C. Relative humidity is 40-60%. The air exchange rate is 1.5-2.5. Airing 10 minutes every 1.5 hours. The concentration of harmful substances in the air in rooms with permanent residence of children should not exceed the maximum permissible concentrations (MAC). These rules are not always respected for various reasons. This is especially true for ventilation and maintaining the desired humidity.

What air purification devices can be used in kindergartens and schools?

• medical bactericidal ultraviolet irradiators - recirculators.
• medical photocatalytic air purifiers
• household and industrial air purification devices, including ionizers.
• domestic and industrial air humidifiers.
• medical humidifiers with the function of volumetric disinfection.

Each type of instrument has its own advantages and disadvantages. Read more below

Germicidal recirculator or UV irradiator closed type.

A bactericidal recirculator or closed-type UV irradiator is a medical device for air disinfection in the presence of people. Used throughout hospitals. The most popular and in kindergartens. The action is based on ultraviolet irradiation of the air passing through the chamber under the action of fans.

Very simple to perform. They consist of a housing, ultraviolet spectrum lamps, a fan, power supplies and controls. As a rule, they have a lamp operating time counter. Thanks to the protective screen, ultraviolet rays do not go outside the device. Lamps must be replaced after 8000 - 9000 hours.

Irradiators OPEN are distinguished by the absence of fans and the absence of a protective screen in the case. The action is based on direct irradiation of the entire volume of air in the room in the absence of people. It is not advisable to use such devices in children's institutions.

Advantages of bactericidal recirculators

• It has long been used in medical institutions. There are certificates of "Roszdravnadzor" for all devices
• High level of consumer confidence.
• Easy to maintain.
• High rates of air purification from viruses and bacteria
• Ultraviolet rays can neutralize some toxic chemicals.
• When air is irradiated, the ion balance is restored.

Cons of bactericidal recirculators

• It is necessary to change the lamps after 8000-9000 hours. (1 year continuous operation)
• Do not remove dust, aerosols, mold spores and some bacteria from the air.
• Low efficiency in air purification from toxic chemical compounds.

Bactericidal recirculators from different manufacturers practically do not have significant differences. All use standard 15 and 30 watt lamps and commercially available fans for system units. The main differences between devices of different brands are the price and case design.

Photocatalytic air purifiers.

Photocatalytic purifier is relative the new kind devices used for air purification and disinfection in medical institutions, in industry and at home. The principle of operation is the oxidation and destruction of microorganisms and toxic chemical compounds on the catalyst under the action of ultraviolet rays. They have a wider spectrum of action than UV recirculators. Cleaning is done in the presence of people. All photocatalytic cleaners have dust filters.

Advantages of photocatalytic air purifiers.

• Used in medical institutions. Some devices are certified by Roszdravnadzor.
• High rates of air purification from viruses, bacteria, mold spores.
• They clean the air of most toxic chemicals.
• They clean the air from dust and aerosols.
• When air is cleaned, the ionic balance is restored

Cons of photocatalytic air purifiers.

• Dust filters should be changed every 4 to 12 months. (depending on model)

spraying disinfectant solutions in the presence of people - comparatively new way combating airborne infections. The technology is simple and effective. Water containing active ingredients is sprayed with an ultrasonic humidifier. Silver ions or ozone dissolved in water are used as a disinfectant. To date, Roszdravnadzor has allowed for use in medical institutions only devices using silver ions (humidifiers "Aquakom") The effectiveness of this equipment has been confirmed by numerous clinical studies.

The main advantage of these technologies is that the processing is carried out simultaneously in the entire volume of the room.

The second significant advantage is that these devices are able to maintain the required humidity in the room.

The disadvantages include the need for daily maintenance - adding water.

How are medical devices different from household ones?

• Medical devices have certificates confirming their effectiveness against the tested types of bacteria and viruses.
• Medical devices tend to have lower performance than household devices for the same price.
• Household appliances have more cleaning levels.
• Household appliances have a more modern and high-quality design and a more modern control system.
• Both household and medical appliances are safe to use around children.

How to choose a device for a specific room?

• The air purifier can only effectively purify the air in the room where it is installed.
• The performance of the device must correspond to the volume of the room. Manufacturers of medical equipment recommend a single passage of the entire volume of air in the room through the recirculator in one hour. But in kindergartens, the population density is very high. More than in hospitals several times. Therefore, it is worth increasing the air circulation rate. The more air passes through the device, the lower the concentration of pathogens in the air will be. According to various estimates, the optimal rate of air circulation through the device is from 1 to 3. Ie. the entire volume of air must pass through the device one to three times per hour. For example. The volume of the game room is 100 cubic meters. We need a device with a capacity of 100 to 300 m3 per hour.
  
• Two devices with a capacity of 50 m3/h. located in different places of the room is better than one per 100 m3 / h.
  

Mobile or stationary.

• This can be dangerous as the appliance is within reach of children. Children can try to play with it. The device is not very stable, and mercury lamps are installed inside most recirculators.
• We know from experience that a mobile device does not actually move during operation. When buying, many expect that the staff will move it from room to room after the children, but this does not happen. The device is in one corner, and is not always turned on, because. they forget to turn it on after the move.
• The mobile device takes up a lot of space.
• A mobile device is more expensive than a stationary one. Often for the same money you can buy two stationary ones.
• The air disinfection device is NOT instantaneous. He needs time to clear the air. It is better that the device works constantly.
• As experience shows, disinfection devices that no one moves or touches work most effectively, i.e. on the principle of "Enable and forget".

How often should the air disinfection device be switched on?

The air cleaner must operate continuously in the presence of people. People breathe continuously and exhale viruses and bacteria with the air.

The best option would be to install a device with a weekly timer. The device itself will turn on in the morning and turn off in the evening, skipping weekends. And you will need to approach such a device only to replace lamps or filters.

Unfortunately, most medical devices do not have daily or weekly timers, and only a few can be operated from an external timer. It is better not to turn off such devices, otherwise they will forget to turn it on.

Unfortunately, almost all children who start going to kindergarten get sick. Usually in gardens does not circulate and clean the air(only periodic, often insufficient, ventilation through the windows). Stagnant air, stuffiness, heat, elevated levels carbon dioxide- an ideal environment for the rapid spread of bacteria and viruses.

For a child to breathe not less than 20 m 3 / h of air, respectively, with an average number of children and staff in the group - 20 people, the minimum air exchange rate is 400 m3/h. Due to natural ventilation through slots in transoms and vents (inflow no more than 5-10 m 3 / h through 1 window) it is impossible to provide even the minimum inflow rate. Hourly full ventilation of the room open windows, especially in the cold season, is dangerous for the health of children. Usually, the premises of the gardens are ventilated only while the children are out for a walk - 1-2 times a day, in cold and hot weather for only a few minutes, so that the air in the room has time to warm up / cool down by the time the children return.

How can this problem be solved?

1. Install supply ventilation (ventilators) of sufficient capacity, equipped with filters with the maximum level of air purification

Supply ventilation constantly supplies fresh air into the room. In the cold season, you can turn on the air heating up to comfortable temperature. The ventilators are equipped with fine air filters that do not let air into the room. tiny particles dust, pollen, viruses, allergens, bacteria, carcinogens, exhaust gases and other harmful substances, as well as odors. The internal walls of the device are heat and noise insulated.

In this way in the kindergarten fresh clean air, rich in oxygen, at the right temperature will constantly enter. Air exchange will improve: forced ventilation stimulates the extraction.

Why will children get sick less? Bacteria, viruses and other harmful substances will not linger in the room. Due to the constant air circulation, the supply of clean air, the normalization of the level of CO 2, the overall microclimate in the room will become healthy. Children will feel better and have stronger immune systems simply by breathing clean, fresh air. For children's institutions, we, first of all, offer a breatherRoyal Clima Brezza with a medical class of supply air purification, which has successfully established itself in the market.

2. Take advantage of the air washer

In winter, the absolute moisture content of the outdoor air is low, and when the radiators are running, the relative humidity drops to a minimum. Why is low humidity dangerous? Mucous membranes, which have the function of counteracting harmful viruses and bacteria, lose their effectiveness several times, which contributes to the development of infections and respiratory diseases,According to SanPin with the requirements for the work of preschool educational institutions, relative humidity in rooms with children should be 40-60%. However, during heating season humidity itself. does not rise above 20-30%.

Help solve this problem air washer, which not only increases the level of humidity, but also cleans the room from dust, pollen, unpleasant odors. In sinks, unlike ultrasonic humidifiers, the traditional principle of water evaporation is used, so they are completely safe. The sink is easy to use: it is enough to regularly add water to it and periodically wash the drum.

3. Buy an air purifier

The cleaner is designed for continuous prevention against infectious diseases. It protects the room from all infections, allergens, toxins, harmful substances and odors. There are many air purifiers on the market, but for kindergartens we recommend Tion Clever, the class of cleaning and disinfection in which it complies with sanitary standards. We do not consider the purchase of an air purifier to be mandatory. for all kindergartens - this is advisable if the administration does not allow the installation of ventilators (in this case, the purifier is essential for the relative normalization of the microclimate).

At Tion Clever No ultraviolet lamps - accordingly, there are no risks associated with them (harmful radiation, risk of mercury leakage, the need for special disposal of the lamp). Due to the low noise level - quieter than the ticking of a clock - the purifier can be placed in the bedroom.

The disinfector will attract all bacteria, viruses, spores to its filters, and purify the air from all types of contaminants. Viruses and bacteria of all types are not only disinfected on filters with an efficiency of 99.9%, but are completely destroyed. This is a sterile system whose filters will never become a source of infection regardless of operating time.

Installing a purifier or sink- a simpler event, since such a device only needs to be hung on a wall or placed on the floor, and plugged into an outlet, and for ventilator settings need to drill a hole in the wall. This procedure does not require approval.

Devices work most effectively in combination. Supply unit saturates the room with fresh, clean air. The air washer maintains an optimal level of humidity and cleans the room from dust. The decontaminator at a deeper level cleans and sterilizes the air in the room. These devices will create a favorable microclimate in the kindergarten and significantly reduce the incidence of children.

Description of the problem

Humidity is one of the main parameters of air, which has a significant impact on humans. Insufficient air humidity leads to a loss of moisture by a person, resulting in drying of the skin, dryness in oral cavity, headache, the children's organism is especially sensitive to humidity. At a low level of humidity, the child's mucosa becomes covered with microcracks, making it easier for bacteria and viruses to enter the child's blood. In an insufficiently humidified room, dust circulation occurs much more intensively. The necessary humidity cannot be obtained in our climate, especially in winter, when the air humidity can drop below 20%, so there is a need to use a humidifier.

Contrary to popular belief, batteries are not the cause of dry air. The relative humidity of the air decreases during heating due to the fact that the maximum possible moisture content of the air increases, while the mass of water vapor in the air remains unchanged.

Given the frequency of ventilation and the size of the premises in kindergartens, it is impossible to achieve the required air humidity by such obsolete methods as frequent wet cleaning or hanging wet rags on radiators. A regular home humidifier will also not provide sufficient performance.

Standard Conditions

According to SANPIN 2.4.1.3049-13, the optimal air humidity in kindergartens and schools should be 40-60%.
Solution options
Ultrasonic humidifiers are ideal for use in kindergartens and schools. Specify the required performance of the humidifier with our specialists.

• Such humidifiers have a number of advantages:
• Easy to install, maintain and operate;
• They have a compact size, harmoniously fit into the room;
• Have no external moving parts, safe for children;
• Economical consumption of electrical energy;
• It is not safe to use steam generators in children's rooms, since the temperature of the steam is quite high and it is necessary to provide protection against getting it on children.

Humidification systems high pressure in kindergartens, it is inconvenient to use, since there is not enough space for placing nozzles and a high-pressure piping system.

An ultrasonic humidifier is installed anywhere in the room, the mist is sprayed from the device by a fan, water is poured into a special tank. The humidifier operates from a 220 V network. To start working, it is enough to fill water into the humidifier tank, plug the device into the network, set the required humidity and turn it on.

In humidifiers, it is desirable to use non-hard water. Prolonged use of untreated water hardness leads to the formation of limescale, and requires regular cleaning ceramic discs. The use of untreated water leads to premature wear of the ceramic resonators and the ultrasonic emitter.
