Air filters in the apartment. Supply ventilation with air filtration and heating

More and more people living in megacities or even in medium-sized cities are increasingly thinking about how to clean the air in their apartments from substances harmful to humans that can cause various diseases or allergic reactions. This problem can be solved by using one of the types of air purifiers, of which there are plenty today in specialized stores, for every taste and budget.

Which air purifier to choose for an apartment is a question that arises among all consumers who have decided to purchase this useful, and sometimes simply vital, device. Air purifiers, as a rule, are sold in specialized stores that sell climate control equipment, and they offer such a wide range that it is easy to get confused when choosing the right model. Therefore, before you go shopping, it is worth understanding all the advantages and disadvantages of devices that purify the air in different ways.

Main types of cleaners and their purposes

There are different types of purifiers on the market that use different operating principles, and each can solve certain air pollution problems better than others. The most important component in the design of air purifiers is the filter - the quality of cleaning the respiratory environment around a person depends on it. Having an idea of ​​the characteristics of filters and their capabilities, it will be easier to decide which one is more suitable for a particular case.

Devices with plasma (electrostatic) filters

Devices that purify air using a plasma filter, which creates an electrostatic field that attracts dust, have proven themselves well among consumers. The metal plates that act as a filter of this type are easy to wash, so they will not require replacement - this factor is also quite attractive to users.

The principle of operation of “cold plasma” - electrostatic air filtration

However, electrostatic devices are designed to remove a certain amount of dust from the air, which is 85-90%, and if there is too much of it, they may simply not be able to cope with it completely. Therefore, if better cleaning of the air masses of an apartment is required, for example, if allergy sufferers or people with asthma live in it, you should choose a device that includes several degrees of purification.

Devices – air ionizers

Ionizers are a complex consisting of several elements that carry out cleaning using different methods, so they are able to free air masses from various harmful impurities.

Air purification with this device is carried out in several stages:

• A powerful fan installed inside the device draws in contaminated air masses.
• Next, the air is pre-cleaned using a coarse foam filter, which traps large dust particles.
• Then, in the air entering the photocatalyst filter, chemical and toxic substances are destroyed, and unpleasant odors are eliminated.

• The germicidal ultraviolet lamp disinfects the air.
• Further, the plates in which the electrostatic field is created retain the smaller dust particles remaining in the air.
• Then negative ions generated in a special device are supplied to the air flow.
• The last stage of the process, disinfected and dust-free air, is supplied to the room through the outlet grille of the device.

The advantage of air purifiers of this class is that they do not collect dust inside themselves, so the filter does not have to be changed, which will help avoid significant costs for servicing the device. It will be enough to periodically wash the metal plates and vacuum the pre-cleaning filter. However, when using this type of air purifier, it is necessary to carry out wet or dry cleaning in the apartment as often as possible, removing dust from the surfaces that settles on them.

Devices with HEPA filters

If high-quality air purification from dust is required, then devices with HEPA filters are the best option. The HEPA filter module itself (from the English “High Efficiency Particulate Arrestance”, that is, literally “highly effective particle retention”) is a special configuration of fibrous material folded into an “accordion”, with gaps between the fibers not exceeding a few microns.

A fan installed inside the device draws in air masses, which, passing through the HEPA filter, are completely cleaned of even microscopic particles of dust, bacteria contained in it, as well as pollen of various plants by almost 100%. Therefore, this type of air purifier is perfect for apartments where people with a predisposition to allergic reactions live.

The device is cleared of accumulated dust using a vacuum cleaner once a month, and the filter module is usually replaced once or twice a year, depending on its contamination and the quality of air purification.

Photocatalyst cleaners

Photocatalytic air purifiers, like the HEPA filter, include several stages of cleaning, so they can cope not only with dust particles of various sizes in the air, but also with dust mites and mold and fungal spores. But these factors are one of the main reasons for the manifestation of allergies in various forms.

This type of air purifier necessarily has a catalyst and an ultraviolet radiation lamp in its design, but in addition, the device can be supplemented with an ion generator, plates that create an electrostatic field, or a carbon filter.

Polluted air enters the device body through a pre-filter dust filter installed at the inlet, and most of the large dust particles, as well as animal hair, are retained in it.

Next, it enters a chamber where two factors interact - a catalyst and ultraviolet light emanating from a lamp, as a result of which the process of photocatalysis occurs, during which toxic pollutants in the air decompose into harmless substances such as oxygen, water and carbon dioxide . Thus, virtually no dust deposits accumulate inside the device, so it does not require frequent filter replacement.

An air purifier, the operation of which is based on photocatalysis, is able to cope with the following negative factors:

• Phenol and formaldehyde fumes emitted from building materials from which furniture is made, for example, chipboard or fiberboard.
• Exhaust gas entering the apartment through gaps in window openings if the house is located near busy highways.
• Carbon monoxide and soot that can appear in the air when burning a fireplace or stove.
• Tobacco smoke and persistent tobacco smell.
• Dust containing various harmful microorganisms - viruses and bacteria.
• Allergens of plant, household or animal origin.
• Toxic organic compounds that can come from solutions and powders of household chemicals.

Thus, photocatalysis can be called one of the most effective ways to clean air from pollutants. In addition, a device of this class usually consumes a small amount of electricity, is environmentally friendly and safe, and requires minimal maintenance - cleaning with a vacuum cleaner once every six months.

The disadvantage of this air purifier is the excessive purification of air masses, that is, not only from harmful microorganisms, but also from neutral ones, since it is not able to distinguish between them. This factor can negatively affect the child’s immunity, so you should not get carried away with excessive cleaning of the rooms where children live.

Air purifier - ozonizer

An ozonizer is a device that purifies the air by releasing a small amount of ozone. Ozone is a gas, a derivative of ordinary oxygen, which in high concentrations is destructive to all living things, which is why it is used to destroy microbes and disinfect rooms. The gas arises as a result of the action of an electric discharge on oxygen, splitting it into atoms - this process is familiar to everyone, since it occurs naturally during a thunderstorm, and after it a characteristic ozone smell appears on the street.

The operating principle of the device is basically based on the natural phenomenon of the collision of oxygen in the air with an electric current, which occurs artificially in the ozonizer, resulting in the formation of ozone.

air purifier

There are different designs of ozonizers, which may differ from each other in some details, but each of the devices also has elements integral to them - these are ozone generators (they can also differ in design), a mains voltage to high-voltage converter and a fan.

This device is quite popular for use at home, as it can create a number of positive effects:

• Disinfection of air masses in a house or apartment from pathogens, including mold.
• Removing rooms from putrid odors.
• Purification of drinking water from chlorine and harmful metals.
• Cleansing foods such as fruits, vegetables and meat from antibiotics and chemicals.
• Disinfection and removal of odors from refrigerators.
• Ozone treatment of bedding, as well as underwear, shoes and even furniture.
• Cleaning mold from air conditioning filters.

However, despite all the positive qualities of the ozonizer, doctors warn against overdose of its impact on the air environment around humans. It is recommended to use it carefully in everyday life, strictly adhering to the instructions included with it. Some experts advise using this device only at times when there are no people in the house.

Air purifiers with carbon filters

Air purifiers equipped with carbon filters belong to the class of fine cleaning devices and are capable of purifying air masses of various impurities, including gases. Typically, such purifiers are additionally equipped with a pre-purification element, as well as such as a HEPA or photocatalytic filter, since carbon filters are not able to efficiently clean the air masses of environmental pollutants, which abound in urban apartments. In addition to additional filters, ultraviolet radiation lamps are added to this type of purifier, which are a good barrier to biological contaminants in the air.

Carbon filters can be filled with fine powdered activated charcoal, which creates high resistance to air flow. It follows from this that it is better to choose air purifiers with a filter that contain large granules. In addition, a corrugated carbon filter is more effective for air purification than a universal mesh filter, since it has a larger absorption area for small and large dust particles. Therefore, when choosing a device, you need to pay special attention to this fact.

Carbon filters in purifiers are changed twice a year, otherwise they themselves begin to pollute the air - this is one of the characteristic disadvantages of devices of this class.

You should not install devices with carbon filters in rooms with high humidity, since carbon absorbs moisture well, “sinters” and quickly loses its flowability and, accordingly, its cleaning properties.

Hydrofiltration or air washing

Purifiers that use hydrofiltration or air washing work as follows:

• Air masses from the room are drawn into the device using a fan.
• Next, they enter the zone where, due to special rotary impellers with blades of a special configuration, they are mixed with water until an almost dispersed mixture is formed, and are cleaned from various impurities that settle in the pan of the device. Next, the purified air is separated and directed towards the outlet openings.

• Typically, air washers have ultraviolet and photocatalytic cleaning functions that are activated when necessary. When they interact, the most effective result is achieved - the device removes viruses, mold spores and various odors from the air.
• In addition, an air ionization module can be built into the general purification - it is negative ions that make the air cleaner and fresher
• Purified and humidified air is supplied to the room.

Thus, such a device performs several functions - it humidifies the air in the room and removes small and large dust particles from it along with allergens, and also cleans it of foreign odors. The efficiency of air purification using such a sink is estimated at 85÷95%.

Humidifiers-air purifiers

An air humidifier is a device that creates an atmosphere in a room with the most comfortable level of humidity for a person by supplying purified steam. The device is configured by the owner himself, using the spray intensity regulator.

Humidifiers are divided into three types - ultrasonic, steam and traditional mechanical devices, but all of them also function as an air purifier. The operating principle of these devices is based on the evaporation of moisture or the formation of vapor as a result of ultrasonic exposure. Most household installations of this class are capable of not only humidifying, but also aromatizing the air.

• Ultrasonic devices are among the more modern options for humidifiers. They are equipped with a special ultrasonic membrane, upon contact with which water splits into tiny particles, thus turning it into cold or heated steam. Spraying of the formed steam is carried out using a fan installed inside the apparatus.

The device is absolutely safe in all respects, so it can be installed in a child’s room, especially since it operates almost silently. In addition, the humidifier is energy efficient and easy to operate.

air purifier for apartment

• Mechanical humidifiers are considered traditional and the simplest in design. A certain volume of water is poured into a small water tank located inside the device body, from there it flows onto special humidifying cartridges, through which air is driven using a fan built into the middle of the device. When humidifying the air, it is also cleared of dust particles. An important disadvantage of such devices for many consumers is the fairly high noise level during their operation.

• Steam appliances humidify rooms with hot steam, which is formed when water is heated to the boiling stage in a special insulated chamber equipped with a heating element with a non-stick coating. The disadvantages of such devices include very hot steam coming out, which can easily get burned, the noise of the humidifier during its operation, as well as high electricity consumption.

The positive qualities of a steam humidifier include the following:

- the ability to use it as an inhaler - some models of devices come with special attachments for carrying out such physiotherapeutic procedures;

— the device is undemanding regarding the purity and hardness of the water, so during inhalation you can safely add aromatic oils to it;

- the humidifier, with its high performance, does not require the purchase of consumables at all - ordinary water is enough.

• Devices with a combined design combine a humidifier and a room air purifier. The fan draws in dirty air, which enters the rotating plastic discs built into the device, located in a container of water. In this department, the air is purified and humidified, and dust precipitates. Therefore, such devices require periodic cleaning and rinsing. The quality of air purification when using this device is 85÷90%.

Additional functions of air purifiers

Most models of air purifiers and humidifiers are equipped with additional functions that simplify and make the operation of the devices as comfortable as possible. These include the following functions:

• Regulator of the intensity of the device.
• Remote control.
• Display for displaying information about operating modes.

• Detectors that determine the level of air pollution, with which you can select the correct operating mode.
• Aromatization and inhalation function.
• A timer that allows you to set the operating time and even carry out specific programming of modes.

Criteria for choosing an air purifier

So, having figured out what types of air purifiers there are, now you should determine what you need to pay attention to when purchasing a device.

• Any model of air purifier is designed according to its capabilities for a certain area of ​​the room, therefore, first of all, it is necessary to clarify this parameter.

In addition, you must immediately decide whether one or more air purifiers will be purchased, that is, the device will be moved from room to room or fixed permanently:

— If a separate purifier is provided for each room, then it is chosen exactly in accordance with its area.

— Provided that one purifier is used in different rooms, its power is selected according to the area of ​​the largest room.

— If you plan to clean a very small room, then you can use an air purifier designed for the interior of a car, since it has a fairly high power.

• The second question to be answered when choosing an air purification device is what types of pollution the air masses should be freed from.
• Next, it is advisable to immediately decide on the comfort of servicing the air purifier, that is, clarify which filter should be installed in it - a replaceable one or one that can be cleaned with a vacuum cleaner or rinsing under running water (the latter option will help to avoid unnecessary operating costs).

— If you decide to choose a non-replaceable filter, then you should purchase photocatalytic, plasma (electrostatic) air purifiers or ozonizers, ionizers, as well as devices with an air washing function.

— In the case where preference is given to a purifier with replaceable filters, you need to ensure that it is equipped with an ionization function. This factor is extremely important, since the air, going through the process of any filtration, loses not only harmful components, but also its beneficial qualities, that is, it becomes to a certain extent even dangerous for apartment residents, so it should be enriched with ions.

• The air purifier will work effectively if you clean it or change filters on time. Therefore, you need to decide on the amount of time that can be allocated for its maintenance.

— If the device can be monitored daily, then you can choose a purifier with an “air washing” function or humidification. In such models, water is changed or added once every two to three days, and its quantity is checked every day.

— The electrostatic air purifier must be serviced once a week - the electrostatic plates, which act as a filter, attract dust particles, are washed.

— If it is possible to service the device only once a month, then you should choose a photocatalytic purifier, an ozonizer, an ionizer, or devices with replaceable filters, for example, with a HEPA filter - it will be enough to clean them from dust with a vacuum cleaner once a month.

air purifier Ecology

• The next question that needs to be answered is how often will the device itself be used? It is advisable to use it constantly so that the air in the apartment is always clean.

— If the air purifier operates around the clock and you want to save on electricity, you should choose a device that consumes low power. This parameter can be found on the device packaging or in its data sheet.

— If the purifier will be used periodically, that is, turned off for a long time, then you should not choose a humidifier or “air washer,” since if there is water left in such a device and it is not cleaned in time, then the contents may “sour,” and this the smell will remain in the container for a long time.

— If the user is ready to strictly follow all the instructions included with the product - clean and dry the device in a timely manner, then you can choose any option with the required parameters.

• Next, you should decide on the functions that the air purifier should perform - this is the most important criterion when choosing it.

• Another important factor is the noise level of the air purifier. In order not to cause discomfort to all residents of the apartment, you should purchase a device that has a night mode function or even a completely silent model. Such air purifiers include photocatalytic ones, ionizers, and those without a fan or with a fan shutdown function.
• When deciding to purchase an air purification device, you must immediately decide on its installation location. On sale you can find floor, wall and tabletop options. It is better not to choose the latter if there is a small child in the house, or, as a last resort, pre-determine a place for him at a certain height that is unattainable for the baby. In addition, it is necessary to take into account the size of the device, since many floor-standing devices must be installed 150÷500 mm from the wall, and only such an arrangement will make it work effectively.
• It is recommended to make a list of all the necessary functions and features that an air purifier should have, and with a ready list of requirements go to the store or online shopping sites.

To maintain an optimal microclimate and guaranteed clean and, most importantly, safe air, an air purifier from dust for the home is an irreplaceable thing. Designed specifically to solve the problem of dry, dust-laden and odor-poisoned air, the devices should be used in every room where people visit, regardless of its purpose. It is, however, important to select appliances by taking a number of factors into account.

Room area and purifier - how are they related?

To ensure that cleaning the air from dust in an apartment does not turn into a quest called “Move the purifier from room to room,” you need to select a model in advance that can cope with cleaning and humidifying the air in each room. That is why the primary factor is the area of ​​the house, apartment or office.

The larger the room, the more powerful and productive the air purification device should be. Accordingly, in compact rooms it is advisable to use low-performance, small-sized models, including car air purifiers.

Types of cleaners: choice depending on functionality

To choose the right air purifier, it is important to determine the problem that needs to be solved and only on this basis analyze the functionality of the models on the market. There are several main types of devices with different sets of functions:

• air washers;
• purifiers with dry filters;
• ionizer cleaners.

Each device from the presented categories works as a dust absorber according to a special principle.

Some of the most productive are air washers. In addition to air purification, their task also includes humidification. The devices are presented in the form of plastic containers with water, into which the same plastic disks are partially immersed, blown by air generated from a fan. The blades catch particles of dust and dirt, immediately washing them away from the surface in the water of the container due to permanent rotation.

Almost every such air purifier/humidifier looks identical to other devices with a similar set of functions and differs only in fan power, blade dimensions and design. Some models are equipped with additional features.

Air washers have both advantages and disadvantages. The first include:

• Economical in operation (electricity consumption up to 400 watts).
• Silence.
• Easy to use and maintain.

The disadvantages include the slow operating process without the ability to connect express mode, as well as the risk of spreading bacteria, for which a warm and humid environment is ideal. The last point can be easily prevented if you clean the device in a timely manner, following the manufacturer's recommendations regarding maintenance.

Air purifiers with dry filters are another type of device for maintaining a normal, safe microclimate in a room. Each such dust catcher is characterized by high power ratings, which is often the determining factor in favor of choosing them.

The design of the units involves the passage of air flows through a filtration system under pressure due to an electric fan mounted in front of the grille.

There are several options for filters used to operate devices. These are preliminary coarse cleaning systems in the form of a sponge-mesh for particles ranging in size from 1 to 5 microns, fine cleaning systems in the form of a frame with material having microscopic holes and the latest HEPA filters that trap the smallest particles of dust and dirt.

The principle of operation of the device is in many ways similar to the principle of operation of a vacuum cleaner with a closed chamber in front of the filters. The advantages of the devices include productivity, express cleaning function in a short period of time and a wide range. Disadvantages include the high noise level during operation due to powerful fans and uneconomical power consumption.

Filter devices for air purification with ionization function are a modern solution for a home or apartment. The devices are capable of attracting even the finest dust, purifying the air simply by creating an electric field. The result is purified and neutralized air without unnecessary noise and energy consumption.

How to make the right choice

Based on the properties and features of the devices used for air purification described above, we can make a conclusion about which device is suitable in a given situation. Much depends on the tasks set, the requirements for energy consumption, the noise level of the device, dimensions and even design.

How to effectively get rid of dust

Despite the wide range of household appliances for cleaning premises, getting rid of dirt, allergens and simple dust particles in an apartment is not as easy as it seems. Even with the most thorough cleaning and disinfection of the air, the amount of harmful impurities can lead to allergic reactions, disruption of metabolic processes in the body and complex diseases. To prevent cleanliness and maintain a healthy microclimate, it is recommended to use household air purifiers, developed by manufacturers in various configurations. A classic air purifier is a multifunctional technique with several replaceable and stationary filter elements, each of which is configured to combat specific biological, organic and molecular bacteria.

Selecting cleaners based on characteristics and functionality

To combat dust and pathogenic bacteria, several types of household air disinfection systems are presented on the climate control market. Depending on air pollution and area rooms, you can buy one of the special mini stations:

• Electrostatic air purifiers. The operation of the device is based on the collection of microparticles through ionization and attraction of oppositely charged particles. If available ozonation the bactericidal effect of the installation is enhanced. The peculiarity of purifiers of this type is silent operation and safety, which allows the device to be installed in any room, including nursery and a medical ward. The effect of disinfection is the destruction of soot, smoke, large and small microorganisms.
• Air purifier with replaceable HEPA filter. A new generation air purifier that absorbs the most microscopic contaminants, up to 0.3 microns in size. Modern installations have a built-in humidification, ozonation and ionization system. The HEPA filter can be changed 1-2 times a year, as it becomes dirty. The result of air treatment has been noted by many users - allergens, microscopic particles of dirt, bacteria and other harmful impurities are removed. Reference: some household appliances in this series are created in a disposable version, without the ability to replace the filter if it gets dirty. This is indicated in the device passport, which is better to inquire about before purchasing.
• Photocatalytic climate filtration systems. Air purifiers of this series are among the most productive devices that clean and disinfect oxygen with a result of up to 99.9%. When the catalyst and UV rays, bacteria, viruses and microorganisms are collected and then broken down into safe carbon dioxide molecules. The entire process of washing the atmosphere takes place at the molecular level, which eliminates the accumulation of decay products inside the mechanism. One UV lamp can be replaced, which fails after 3-4 years of daily use. If you need to get rid of not only viruses, but also dust particles, you should choose multifunctional equipment with a carbon filter or wet cleaning of the space.
• Sinks.Air purifiers with function moisturizing combine two necessary actions - oxygen saturation with water molecules and cleaning the atmospheric layer from any kind of pollution. This technique is recommended for low levels of pollution, when you need to get rid of stench, pet hair and other organic matter, as well as maintain the level of humidity during the heating season .

An air purifier from dust should be selected according to the area of ​​the room and exclusively from trusted manufacturers who provide a guarantee on climate control equipment for at least 1 year.

In modern environmental conditions, it becomes impossible to ventilate a room using an open window, since the risk of penetration of carcinogenic compounds with street air significantly exceeds the expected benefits of ventilation.

And in a large metropolis the streets are so dusty that opening windows is simply unreasonable.

To overcome this impasse, an air purifier for the home was created.

Until now, many people are skeptical about this unique invention, trying to understand whether it is harmful to health. So what are home air purifiers, and which one is better to choose?

The principle of operation of the air purifier is the circular circulation of air - from the external environment through the purifier to the outside. The room is cleaned using built-in filters. The home air environment is characterized by the presence of carcinogenic substances (formaldehyde, benzene, nitrogen dioxide), mold, fungi, bacteria and dust impurities.

When the air flow passes through the air purifier, the harmful microparticles it contains are deposited on the filter of the device.

The biggest concern among people is the electrostatic air purifier. It converts oxygen into ozone, which in large quantities is hazardous to human health. However, manufacturers produce devices with low ozone emissions, which is absolutely safe. It should be remembered when choosing an air purifier, benefits and harms are distributed in a ratio of 95 to 5%. In general, air purifiers are not harmful to people.

Main types

All air purifiers are classified by filtration type:

• mechanical;
• ionic or electrostatic;
• photocatalytic;
• combined.

Mechanical air purifiers contain HEPA air filters and carbon filters. They perfectly purify the air from house and construction dust, cope a little worse with bacteria and allergens, but are ineffective against viruses and gaseous compounds. You can make such an air purifier with your own hands, using filters and a fan.

An ionic air purifier (electrostatic) operates using an electrode that charges neutral air particles and attracts them to itself. It copes well with allergens, dust mites, viruses and bacteria, but is not able to clean the room from toxic gases. In addition, the air purifier ionizer fills the room with freshness.

An air purifier with a photocatalytic filter purifies the air in the home using UV radiation. It is effective against any microorganisms, allergens, toxic gases, but is not able to cope with organic impurities.

A cleaner with a UV lamp completely kills all microorganisms and literally sterilizes the room.

Combined purifiers are characterized by a multi-stage cleaning system and include all of the above filters. With the help of these devices, the air is simultaneously disinfected, cleaned of organic impurities and ionized.

How to choose

When choosing an air purifier the following factors must be taken into account:

1. Room area. All devices have a different range of action: from 10 m2 to 150 m2. It is especially important to consider the area when choosing a device that contains an ionizer purifier, since the ozone concentration it emits is calculated for a certain range of action.
2. Noise level. Devices with mechanical cleaning are characterized by noise during operation, this is due to the action of the built-in fan. The quietest option is an ionic purifier.
3. Dust content. With the greatest accumulation of dust and organic impurities (animal hair), it is more advisable to choose an option with mechanical or ionic cleaning.
4. Allergic reactions. Purifiers with ionic and photocatalytic filters do an excellent job of removing any household allergens (dust mites, plant pollen). However, if the allergy is caused by animal hair, then the best assistant in this matter is a HEPA filter.
5. Smoke and smells. Devices with an ionizer and carbon filtration will help you cope with tobacco smoke and unpleasant odors.
6. Disinfection. Maximum air disinfection is achieved by using a UV lamp.

As a rule, the device is turned on daily for several hours or left overnight. Some devices are equipped with an air control function and operate according to the air atmosphere.

Electrostatic and photocatalytic purifiers do not require filter replacement, unlike mechanical ones. Therefore, before choosing an air purifier for your home, you need to decide on the frequency of its use.

Filters in air purifiers

The following types of filters are used in air purifiers:

1. Pre-cleaning. Conventional mesh filters, which are used at the first stage of cleaning, trap large particles of dust and animal hair.
2. HEPA filters. They are an accordion assembled on both sides with micro-holes. They cope with mold and fungi spores, animal hair, and dust mites.
3. Coal. Fights dust and absorbs odors using activated carbon.
4. Electrostatic (ionic).They work on the principle of ionization, provide a high degree of purification, and cope with microorganisms.
5. Photocatalytic. Purify the air using UV radiation. They completely disinfect the room from pathogenic bacteria and carcinogenic substances.

Air purifier operating instructions

The air purifier should be installed in areas where dust accumulates the most to operate effectively.

The device should not be adjacent to the wall, but located at a distance of at least 10 cm from it. For the purifier to work, you must plug it into the network and set the cleaning mode in accordance with the instructions.

Almost all modern models have electronic control and filter replacement indicators. The device's replacement filters must be replaced every 2 months. The ionizer plates should be wiped with a damp cloth at least once a week.

An air purifier for the home is a useful thing, cleaning the air space as much as possible. When choosing a device, you should take into account the area of ​​the room and its pollution factors.

The best option is a combined air purifier from dust, carcinogens, allergens and bacteria, which includes a multi-stage cleaning system.

One of the main parameters when choosing an air purifier is its performance - it determines how efficiently the device can work in a particular room.

To select a device based on performance, you should calculate the volume of the room (multiply the area by the height of the ceiling) and find a model that “processes” 2-3 times more air per hour - this is considered the best option. Many manufacturers indicate the maximum room area in the specifications; this parameter can be calculated using different formulas and for different types of premises, and therefore it is still advisable to choose a device based on volume, and not on area.

Purifiers can be equipped with various types of filters. It all depends on what contaminants need to be removed from the air:

• For mechanical cleaning (from wool, fluff, dust, etc.), preliminary, electrostatic, HEPA and NANO filters, as well as hydrofiltration, are used. The first two types retain large and medium-sized particles, HEPA and the hydrofilter are microscopic (the latter also humidifies the air), NANO works at the molecular level.
• A carbon filter is useful for dealing with chemical contaminants. In this case, it is especially important to change the filter on time - having exhausted its resource, it itself becomes a source of harmful substances. The ideal option is an air purifier with a filter contamination indicator.
• The UV lamp is designed to eliminate bacteria and viruses. Also, the efficiency of disinfection increases significantly if the purifier has an ozonation function.
• The photocatalyst combines the functions of all three types and is considered the most advanced to date, however, it costs accordingly.

For maximum efficiency, it is recommended to use several types of filters at once.

Purifiers are available with an automatic switch-on function, which makes the device independent of the user: it turns on itself, detecting contaminants in the air. Such models are as convenient as possible, because... can work unattended (although you still shouldn’t completely forget about the turned on purifier).

For constant use in apartments or other premises, air purifiers powered by a 220 V network are best suited. Battery or accumulator power is recommended when independence from outlets is needed (for example, when installed in a refrigerator). For cars and buses, models are available with 12 V power from the cigarette lighter socket.

Some air purifiers can not only filter the air, but also saturate it with negative ions that have a beneficial effect on health (ionizer), or pleasant aromas (aromatizer).

If there are small children in the apartment, you should choose a device with a child lock feature.
