sale presents a variety of types of cleaners that use different operating principles, and each of them is able to solve certain air pollution problems better than others.The most important element in the design of air cleaners is the filter - that it determines the quality of the human environment of the respiratory treatment.Having an idea of ​​the characteristics of filters and their capabilities, it would be easier to decide which one is more suitable for a particular application.

instruments with plasma (electrostatic) filter

However, electrostatic devices designed to remove from the air a certain amount of dust, which is 85 ÷ 90%, and if it is too much, then they can just to her fullnot cope.Therefore, if you want a high-quality cleaning of air masses apartments, for example, if there are living people with allergies or who are suffering from asthma, you should choose the device that includes multiple stages of purification.

devices - air ionizers

Ionizers are a complex consisting of several elements, conducting purification by various methods, so it is able to release the air masses from various harmful impurities.

Air purification device that is carried out in several stages:

  • inside the unit powerful fan draws in contaminated air masses.
  • Further, there is a preliminary air cleaning with the foam pre-filter, which traps larger particles of dust.
  • Then, in the air, gets into fotokatalizatorny filter destroyed chemical and toxic substances and odors.

  • germicidal UV lamp produces air disinfection.
  • Further, plates in which an electrostatic field is created, smaller hold remaining airborne dust particles.
  • then fed negative ions generated in a special device in the air.
  • last stage of the process, the last disinfection and cleaned of dust air is fed into the room through an outlet grille device.

advantage of air cleaners this class can be called what they are not collected within the dust, so it is not the filter should be changed to help avoid significant expenses for maintenance of the device.It will be sufficient to carry out periodic washing of metal plates, and vacuum the pre-filter.However, using this type of air purifier, you need a wet or dry cleaning of the apartment can be carried out more frequently, removing from the surfaces of deposited dust on them.

devices with HEPA filters

fan installed inside the device draws in air masses, which, passing through the HEPA filter, fully cleaned even microscopic dust particles in it of bacteria and pollenvarious plants almost 100%.Therefore, this type of air purifier is perfect for apartments, where there are people with a predisposition to allergic reactions.

The device is released from the accumulated dust with a vacuum cleaner once a month, and the replacement of the filter unit is usually done once or twice a year, depending on the contamination and cleaning of air quality.

Photocatalytic air purifiers as well as a HEPA filter, include severalpurification steps, so are able to cope not only with the different sizes of dust particles in the air, but also dust mites and mold spores and fungi.But these factors are a major cause of allergy in various forms.

Such kind of air purifiers is necessarily in its design and catalyst ultraviolet lamp, but in addition, the device can be supplemented by the ion generator, plates, creating an electrostatic field or a carbon filter.

Polluted air gets into the housing through the dust pre-filter, installed at the entrance, and it retained a large part of the large particles of dust and animal dander.

Further, it enters the chamber, where they interact by two factors - the catalyst and ultraviolet light from the lamps, so that there is photocatalysis process in which decompose toxic pollution in the air, to safe substances, such as oxygen, water, andcarbon dioxide.Thus, within the device hardly accumulated dust cake, so it does not require frequent filter replacement.

air cleaner, which is based on photocatalysis, able to cope with the following negative factors:

  • vapors of phenol and formaldehyde, allocated from the building materials from which the furniture is made, for example, particleboard or fiberboard.
  • exhaust gas entering the apartment through the gaps in the window openings, if the house is located near busy highways.
  • Carbon monoxide and soot, which can occur in the air at the firebox fireplace or stove.
  • Tobacco smoke and odor resistant tobacco.
  • dust containing various harmful microorganisms - viruses and bacteria.
  • Allergens of plant, animal or domestic origin.
  • toxic organic compounds, which can come from fluids and powders household chemistry.

Thus, photocatalysis can be called one of the most effective ways to clean the air of pollutants.In addition, the device of this class usually consumes a small amount of electricity is environmentally friendly and safe, requiring a minimum of maintenance - cleaning vacuum cleaner once a year.

disadvantage of this can be called excess air cleaner cleaning air mass, that is not only harmful organisms but also on the neutral because it is not able to distinguish between them.This factor may have a negative impact on the child's immunity, so do not get carried away too much cleaning of rooms, where children live.

Air Cleaner - Ozonator

Ozonator - a device that cleans the air by allocating a small amount of ozone.Ozone - a gas derivative conventional oxygen which in high concentrations is destructive to all living things, which is why it is used, and for the destruction of bacteria and disinfection of premises.Gas is the result of the impact of electric discharge on oxygen, splitting it into atoms - a process familiar to everyone, as it occurs in vivo during a lightning storm, and after its characteristic smell of ozone appears on the street.

operation principle is in principle based on the natural phenomenon of air oxygen collision with an electric current that occurs in an artificial way ozonizer, thereby forming ozone.

There are different schemes of ozone, which can differ in some details, but in each of the devices, there are inherent to these elements - is the ozone generator (they can also differ in design), the converter supply voltage in high voltage and fan.

This device is quite popular for use in the home, since it is able to create a number of positive effects:

  • disinfection of air in the house or apartment of pathogens, including mold.
  • Getting premises of putrid odors.
  • purified drinking water from the chlorine and harmful metals.
  • Cleansing products such as fruits, vegetables and meat from antibiotics, chemicals.
  • disinfection and disposal of odors refrigerating chambers.
  • ozone treatment of bedding, as well as underwear, shoes and even furniture.
  • Removal of mold in the air conditioner filter.

However, with all the positive qualities of the Ozonator, doctors warn against overdosing its impact on the human air.It is recommended to use it carefully at home, strictly adhering to the instructions attached.Some experts advise to do to use this device only at a time when there are no people in the house.

Air purifiers with carbon filters

Air, equipped with carbon filters, are a class of thin clearing equipment, and can clean up the air masses of different contaminants, including gases.Typically, these cleaners are equipped with an additional element of the pre-treatment, as well as such as HEPA filter or photocatalytic as carbon filters are not able to qualitatively clear the air masses from the eco-pollutants, which abound in a city apartment.Also additional filters in this kind of cleaners is added ultraviolet light which are good barriers to biological contaminants in the air.

Carbon filters can be filled with fine powder of activated charcoal, which creates a high resistance to air flow.It follows that it is better to choose the air purifier with a filter having in its structure large granules.In addition, corrugated carbon filter is more effective to clean the air than the net universal, because it has a large absorption area of ​​small and large dust particles.Therefore, choosing a device, this fact should be paid special attention.

carbon filters are changed in the cleaners twice a year, or they themselves are beginning to pollute the air - it's one of their typical drawbacks of devices of this class.

not necessary to install, with a charcoal filter equipment in wet areas as well as coal absorbs moisture, "baked" and quickly loses flowability and, consequently, its cleansing qualities.

cleaners that use gidrofiltratsiya or cleaning the air, work as follows:

  • Airmass drawn into the room by the fan unit.
  • Next, they enter a zone where by means of special rotary impellers with blades with a particular configuration are mixed with water to form a mixture substantially dispersed, and are purified from various impurities that are deposited in the tray device.Further, the purified air is separated and directed towards the outlet openings.

  • air sinks usually have a function and ultraviolet photocatalytic purification, which are included as needed.When they interact achieved the most effective result - the device removes air from viruses, mold spores and various odors.
  • addition, general cleaning can be integrated air ionization unit - that negative ions make the air more clean and fresh
  • purified and humidified air is supplied into the room.

Thus, such a device has several functions - it moisturizes the air in the room and removes the small and large particles of dust, along with allergens and cleans it from foreign odors.The effectiveness of air purification using a washing estimated at 85 ÷ 95%.

humidifiers purifiers

air humidifier unit is called, creating the atmosphere of the room with the most comfortable for the human level of moisture by applying the purified steam.Setting up the device is made by the owner, with the help of spray intensity regulator.

Humidifiers are divided into three types - it is ultrasonic, steam and traditional instruments, but they are a function and an air purifier.The principle of operation of these devices is based on the evaporation of moisture or vapors in the e by sonication.Most household installations of this class are able to not only moisturize, but also flavored the air.
