Why is it necessary to humidify the air?
GOST 30494-2011 states that the humidity level in the room should be from 45% to 60%. But in homes and apartments in the air often lacks the necessary moisture.
In winter and in the off-season, the batteries and domestic heaters dry the atmosphere, in the summer the microclimate is changed by the heat and the sun's rays penetrating from the street. Reduced humidity provokes rapid aging of the skin, leads to a decrease in immunity and negatively affects the respiratory tract.
The lack of moisture in the air affects young children the most. They show increased physiological sensitivity to dehydration and feel worse in a room with an overdried atmosphere.Babies have chapped lips, constantly blocking their nose and tickle in the throat. The risk of developing bronchitis and pharyngitis increases.
Types of Humidification Equipment
A wide range of products for humidification of air in residential, office and industrial premises is offered on the home appliance market.
Devices are divided into three types:
Sinks and climatic complexes also belong to humidification equipment, but at the same time they purify the air, and have additional opportunities to increase the comfort of the microclimate in houses and apartments.
Type # 1 - Ultrasound Modules
The ultrasound machine is considered universal and is suitable for servicing children's and living rooms, offices, industrial premises, greenhouses, shops, restaurants and cafes. It produces cold steam during operation.
The built-in piezoelectric element, activated by electric current, creates high-frequency oscillations and converts water into fog from microscopic splashes. The fan draws in dry air, directs it into a water cloud to enrich it with moisture, and then disperses it around the room.
The humidifier easily withstands intense loads and works normally around the clock. For operation, just pour liquid into the tank and plug the device into a power outlet.
Among the advantages of the device:
- the ability to maintain indoor humidity at a high level (up to 80%);
- minimum noise (average - 25 dB);
- low power consumption;
The main disadvantage is the demand for water quality. There are no filtering elements in the device. It is recommended to use only purified (distilled) liquid to fill the tank. Otherwise, white coating will form on the furniture and appliances in the room, and heavy salts and spores of microorganisms will appear in a couple.
Type # 2 - Traditional Humidifiers
The operation of traditional humidifiers is based on cold evaporation. The fan directs air masses to the porous filtering elements which are constantly in contact with water. Having received deep hydration, the air returns back to the room. In this way, it is possible to maintain humidity at 60%.
Aromatic compositions can even be added to the tanks of conventional air humidification devices.
Devices consume a small amount of electricity and are sold at an affordable price. Need to work in demineralized, distilled fluid. The use of tap water provokes a quick clogging of the filters.
Among the significant drawbacks of the modules is the pronounced noise background. Creates its built-in fan. For round-the-clock use in children's rooms and bedrooms, traditional devices are not suitable. Insufficient productivity makes them unsuitable for installation in greenhouses.
Type # 3 - Steam Devices
Steam models work on the principle of an electric kettle. A certain dose of water from the reservoir comes into contact with the heating element, boils and is freed from non-volatile impurities. Steam enters the room and moisturizes the air intensively. Using this type of technique, it is possible to quickly bring the humidity level up to 100%.
Hygrostat for steam humidifiers is an urgent need. Uncontrolled operation of the module can provoke dampness in the room and mold stains.
Cartridges and replaceable filters are absent in the model. This allows you to pour liquid of any quality into the container without fear that some elements will quickly clog or fail. On the one hand, this simplifies use. On the other hand, it causes additional problems in the form of microparticles deposited on various surfaces, forming an unaesthetic dust coating.
Significant disadvantages of the device:
- excessive energy consumption compared to other types of products (from 300 to 600 watts);
- high risk of contact with a jet of hot steam.
Some blame steam devices for a warming body that a small child could accidentally burn themselves in. But such a disadvantage is peculiar only to cheap models of unknown companies.
Reputable brands use heat-resistant modern plastic for the walls. Even in the process of boiling water, it only warms slightly and does not burn the skin when touched.
Type # 4 - domestic climate systems
The climate complex simultaneously performs two functions - naturally moisturizes the air and purifies it. A built-in fan drives air through the evaporator. The porous filter element is located in a container with water and constantly draws moisture up. On a wet surface, dust settles better, the evaporation process is more efficient and gives better results.
In terms of functionality, the complex to support the optimal microclimate is similar to air conditioning. But it is not mounted in one place, but is easily transported and placed in any part of the room. It has a number of additional comfort options. Individual models can heat / cool rooms.
Type # 5 - humidifier-sinks
The sink performs wet mechanical air cleaning thanks to the presence of filters. It consumes little energy and does not overmoisten the microclimate. It is not dangerous for children and adults. They can work using hydrofiltration technology (a curtain of water) or a cold “water bath” (disk rotation).
Let us briefly consider the principle of operation of the device as an example of disk washing. Inside the body of the sink, functioning on the principle of a water bath, there are plastic discs. During rotation, a special coating and relief trap water on the surface of the discs. As a result, a large water area is created. Discs are blown by fans, increasing the evaporation rate. The air is moistened and cleaned of pollen, household dust, animal hair and small particles of dirt.
The device with hydrofiltration technology provides humidification and cleaning by rotating the cone-shaped rod in the center of the liquid container. The work item lifts the water up and creates a veil of microscopic droplets. Passing through it, the air is freed from dust particles and saturated with moisture.

Selection criteria and customer recommendations
To properly buy a device for humidification, you need to know exactly the area of the room where you plan to use it.
Take a weak unit for a spacious room does not make sense. He will not cope with the tasks. Too strong a module in a small room will “eat” more electricity, but will not give any additional effect.
Steam humidifiers should be used only where, for objective reasons, an increased level of humidity is required. For rooms where elderly people or children live, this option is not recommended. Accidental contact with hot steam causes a burn and the use of the appliance leaves an unpleasant impression.
If you want to moisten the air in the bedroom or the nursery, you should choose the most quietly working appliances. Otherwise, fully rest and sleep will be extremely problematic. We talked about the pros and cons of a humidifier for a child and the features of choice in this article.
You will have to pay for all additional features. Therefore, you need to immediately decide which options are really useful, and what you can safely refuse. Auto shut-off when turning over, protection from running without water, an indication of replacing filters and night mode increase operational safety, but affect the cost of the device.
Whether to pay for the rotation of the module, touch screen and remote control, the user will have to decide for himself. If the budget allows, it makes sense to spend money on additional comfort. When funds are limited, you can do without these bonuses.
Next, we consider the main criteria that it is desirable to consider when choosing a household humidifier.
Power, service area and noise
The power range of household humidifiers on the market is 20-600 watts. For small rooms ranging in size from 15 to 30 m2 fit devices up to 100 watts. Larger rooms up to 50 m2 Used models with power ratings up to 150 watts.
In studios, living rooms and bedrooms from 80 m2 modules with power from 240 watts work successfully. Manufacturers usually indicate on the package what area the device can serve.
The noise level depends on the type of humidifier and its power. The optimum is considered to be 20-30 dB. Equipment with such indicators is suitable for round-the-clock work in nurseries, bedrooms and lounges. In living rooms and offices, the installation of devices up to 50 dB is allowed. We recommend that you familiarize yourself with rated quietest humidifiersmost popular among users.
Tank volume and humidification rate
For rooms up to 20 meters, a device with a capacity of 4-5 liters of water is enough. In rooms of size 30-40 m2 it is better to use 6-7-liter devices, and in apartments up to 60 m2 - appliances with a reservoir of 8-9 liters. Humidification speed directly depends on the size of the room, performance and power of the model.
In a 15-meter bedroom or a nursery, it quickly creates an optimal microclimate device with a capacity of 45 m³ / h. For a room of 80 m2 a module with an air exchange rate of 240 m³ / h is required.
Varieties of filtration systems
Each manufacturer of steam humidification equipment uses different cleaning methods.
Most often in devices there are filtration systems of the following types:
- ionizing (electrostatic);
- rough cleaning.
Carbon filter belongs to the class of adsorption purifiers. Contains activated carbon or zeolite. Quickly neutralizes all types of fumes, including tobacco smoke, eliminates unpleasant odors, volatile compounds and aggressive chemical fumes. Must be replaced every 2-4 months (depending on the manufacturer's recommendations).
If the carbon filter is left for a longer period, it becomes clogged with dust. Inside, an environment is formed that is favorable for the accumulation of bacteria and the multiplication of microorganisms. Such a filter no longer performs the cleaning function.
HEPA System performs fine cleaning. Removes up to 100% harmful substances and dirty impurities. Due to its high efficiency, it is suitable for use in medical and child care facilities. It is washing and replaceable. Sold at a higher price, but can be used throughout the year.
Ultraviolet filter cleans the air of fungal spores, allergens and pathogenic bacteria. It does not require laborious care and thorough processing.
Photocatalytic filter guarantees 95 percent cleaning. It removes toxic elements from water, neutralizes their oxidation and decomposition. Eliminates gases, impurities and harmful bacteria. It reliably serves for a long time.
Ionizing (electrostatic) filter delays charged particles up to 0.01 microns in size. Cleans from the smallest dust, aerosols and soot, but can not cope with the removal of toxic substances. It is usually used as an additional element complete with other filters. Sold at a low price and suitable for repeated use.
Coarse filter removes fragments of dirt and large particles of dust. When clogging, it needs to be washed with running water or cleaned with a household vacuum cleaner.
Availability of additional options
Indicator light helps in time to learn about the need to top up water. By eye, determining this point is quite problematic, especially in models with opaque tanks.
The need for replacement / cleaning of working containers, nozzles and filters is reported by a special indicator. Busy owners may forget that their consumables have expired humidifier needs cleaning, and continue to use the device, which no longer performs its functions at the proper level.
System protection against work without water and rollover auto power off increase the safety of the humidifier. If the owners forget to pour water, the unit does not overheat and does not burn out. When a child or pet accidentally touches or knocks over a humidifier, it will not cause a short circuit or fire.
Night mode - Actual option for units with natural humidification and devices with a large display and color indication. For the former, the fan is too noisy, and for the latter, the light elements burn too brightly. In night mode, the fan runs at lower speeds and makes almost no sounds, and the display and display do not light. The air is moistened with high quality, but there are no obstacles to sleep and rest.
Availability hygrostat allows you to control the level of humidity. As soon as the indicator reaches the norm, the device automatically turns off. It is activated again only when the humidity in the room decreases. This increases work efficiency and reduces electrical energy consumption.
Options such as lock when the cover is loose, improper assembly, improper location of the cartridge, etc. They guarantee that the model will begin to work only if all the replaceable elements are correctly installed.
It is convenient when the device rotates around its axis. In this case, the steam is sent in different directions and evenly spreads throughout the room, providing better air humidification.
Separate climatic complexes eliminate static electricity. Devices with this option are recommended to be placed in rooms with a large number of electrical appliances, household appliances and office equipment.
Home appliance manufacturers
Different types of steam humidification equipment are produced by many popular manufacturers of household appliances.
The Swiss company is considered the confident leader in this market segment. Plaston ag. More than half a century under the brand Boneco Air-O-Swiss She makes high-quality devices to create a comfortable and healthy microclimate in the premises.
The assortment line of the brand includes budget and premium traditional, steam and ultrasonic humidifiers, effective climate systems and “air washes”. Each model runs in several series. You can choose a product by color, shape, type of control and other technical specifications.
In second place in popularity are Italian Aircompfort and German Venta. They specialize in the manufacture of humidifiers and air purifiers, introduce innovative technologies into production and are actively working on creating original unit designs.
Air humidifiers and brands such as Electrolux, Philips, Dyson, Supra, Gorenje, Leberg, Polaris and Panasonic. However, these manufacturers do not have a narrow specialization, and it is problematic for them to compete with the first three.
