The air inevitably contains dust, tiny particles, harmful allergens. It is not useful for a healthy person, but for asthmatics and allergy sufferers it is completely dangerous. Special devices are used to purify the air in the room. It is necessary to choose such a device according to certain criteria.

The principle of operation of the air cleaner

Air purifiers are designed to purify the air from unwanted impurities and substances. They do not provide absolute sterility, but they clean the air to a large extent.

air cleaner

The mechanism of operation of the device is quite simple. Inside the device are special filters. The purifier sucks in the air flow that passes through these filters. Cleaned air comes out of the device. The degree of purification is at least 80%. This figure mainly depends on the type of filters used.

Air purifiers may have additional features. They provide getting rid of pathogenic microbes, better air purification and humidification.

Advantages and disadvantages of devices

Air purifiers are in demand not only among allergy sufferers and asthmatics, but also among healthy people. The advantages of such devices are enough:

  • Quality air purification. If you have allergies or asthma, it is especially important that the air is free of dust and pollen. Cleaners do a great job of this.
  • Getting rid of unpleasant odors.
  • The possibility of additional air humidification, which is especially important during the heating season.
  • Low power consumption. Air purifiers have low power, rarely exceeding 50 watts.
  • Compactness. The devices reach half a meter in height, but usually no more than 20 cm in depth. Some devices provide for wall mounting.

Air purifiers have some disadvantages:

  • Noise during operation in some modes. During sleep, many devices provide an almost silent night mode.
  • The need to add water to the reservoir. If the device works around the clock, then you have to add water several times a day.
  • The water tank and fan fins should be cleaned regularly. This should be done every few days.
  • The need to replace and clean the filter. This involves additional costs.

Filter cleaning

Most of the shortcomings are associated with the need to maintain the device, but such care is important for high-quality air purification.

Types of air cleaners

There are several types of air cleaners. The classification is based on the presence of additional functions in the device and the type of filter used for cleaning.

Types of air purifiers suitable for asthmatics and allergy sufferers:

  • Air purifiers. The air flow in such devices is cleaned by the aquatic environment. The design of the device implies the presence of an internal drum with special plates. They attract unwanted particles and harmful impurities that pass through the water and remain in it. In addition to cleaning the air, such devices provide humidification.
  • Humidification devices. Such devices are extremely effective, as they provide a decent degree of cleaning (from 90%) and maintain the optimal level of humidity in the room.
  • Cleaner-ionizer. During the operation of the device, negative ionic particles are formed in large quantities. They eliminate harmful substances, including various allergens.
  • Devices with a HEPA filter. Such a cleaning system is most attractive for people with asthma or allergies. These filters provide a purification rate of 99%.
  • Cleaners-ozonizers. The operation of these devices is based on the synthesis of ozone. This ensures the elimination of toxins and disease-causing microbes.
  • Devices with a photocatalytic filter. In addition to air purification devices provide its maximum disinfection. This effect is provided by a photocatalyst interacting with ultraviolet light.

Air purifiers not suitable for asthmatics and allergy sufferers:

  • Cleaners with electrostatic filter. The attraction of harmful substances is provided by electric discharges. The degree of purification of such devices is at a minimum level (80%), therefore, for allergy sufferers and asthmatics, this option is inappropriate.
  • Appliances with charcoal filter. Among the advantages of this type of cleaning is the elimination of unpleasant odors and low cost. The disadvantage of the device is its low efficiency. The carbon filter does not provide protection against dust and allergens, so this option is not suitable for asthmatics and allergy sufferers.

Floor Air Purifier

Air purifiers can vary in type of humidification. This function can be based on the following principles:

  • Cold evaporation. Humidification is achieved by passing air through a special sponge with antibacterial impregnation.
  • Hot steam. Humidification is provided by the evaporation of water, achieved by the action of temperature. Water is heated by two electrodes. When the temperature reaches the boiling point, the heating will automatically stop.
  • Ultrasound. This option is the most attractive, as it cleans the air efficiently, simultaneously moistening it.

Some devices allow you to adjust the level of humidity. Adjustment can be manual or automatic.

Depending on the power of the device and the possible area of ​​​​use, air purifiers are household and professional. Devices of the first type are used in small rooms: apartments, private houses, offices. Professional devices are designed for larger areas.

Additionally, the device may be provided with the possibility of using aroma oils. They are added to the atomizer so that the air in the room is filled with a pleasant aroma. With allergies or asthma, this supplement should be used carefully.

Criterias of choice

Despite the small functionality of air purifiers, when choosing them, many criteria must be taken into account. The following parameters have meaning:

  • Room size. In case of allergies or asthma, it is advisable to put such a device in all rooms in which a sufficiently large amount of time is spent. If one device is purchased, then the service area should be selected according to the size of the largest room. In this case, the cleaner can be rearranged and it will be effective anywhere in the apartment (home, office).
  • Air exchange. This aspect is important for high-quality air purification. The appliance must pass air through the filters at least twice per hour. This parameter must be correlated with the size of the room. It is important to calculate its cubic volume and multiply by 3.
  • Air washer available.
  • Number of cleaning steps. In this regard, there are three classes of equipment — budget, medium and elite. The first option provides for 2-3 levels of cleaning, the second — up to 6 steps, the elite — up to 9 steps of cleaning.
  • Number of fans. Usually a device with 1-2 fans is enough, but with severe allergies or asthma, their number should be 4-5 pieces.

  • Filter type. For allergy sufferers and asthmatics, it is advisable to choose devices with a photocatalytic or HEPA filter.
  • Possibility of regulation of humidity of air.
  • Additional functionality. The air purifier can be equipped with indicators, timer, child protection, backlight, remote control. Automatic shutdown can be provided, the presence of an LCD display that reflects the main parameters.
  • Noise level. This parameter is extremely important if the device will be in the bedroom. Some purifiers provide a special night mode.

When buying an air purifier, you should consider the totality of all factors. The right device will provide maximum cleaning. Additional functions allow you to make the air even cleaner and normalize its humidity.
