Air conditioners with fine filters for indoor air

The latest models of air conditioners are equipped with filter systems to remove dust, small particles of wool, pollen and even viruses. There are systems that can detect the smell of smoke. To choose climatic equipment for fine cleaning, you need to understand the principles of operation and types of filters.

Why do you need air purification

The indoor air contains dust, soot, microbes, bacteria. Household appliances, household chemicals, perfumes and cosmetics are sources of various chemical compounds floating in the air and entering the lungs when breathing. All this negatively affects people's health. Prolonged stay in a room with polluted air causes:

• headache;
• irritability;
• rapid fatigue;
• drowsiness;
• the development of asthma and allergies;
• decreased immunity.

In rooms with high traffic, the risk of contracting viral and infectious diseases is especially high.

To avoid these problems and create comfortable conditions for work or rest, it is recommended to install an air conditioner with air purification function.

Types of filters and their features

Split systems are equipped with two types of filters:

• rough cleaning;
• fine cleaning.

The first ones are installed in all models of any price category, so the consumer receives elementary air purification from dust in any case. An electrostatic filter is a fine mesh, sometimes covered with a nonwoven fabric. It copes with coarse debris, fluff, animal hair, thereby protecting the heat exchanger of the device.

The second category of filters is installed on more expensive air conditioners with a fine air purification function. The designs are varied. These air conditioners trap dust with particles of 0.01 microns, cigarette smoke, allergens, germs and viruses.

Carbon (deodorizing) carbon filter made from coconut. Retains small particles, odors, harmful chemical compounds.

Photocatalytic filter contains titanium dioxide, which acts as a catalyst. It catches unpleasant odors, viruses and even toxic impurities. Breaks down organic matter into carbon oxides, water and other non-hazardous compounds.

Air conditioners with outdoor air purification with an ultraviolet filter destroy almost all known harmful microbes and viruses and disinfect the air conditioner itself from the inside.

IN plasma filter an ionizer is installed, which creates a voltage of 4800 volts. Under its influence, fungi, viruses, bacteria, pollen, spores, etc. are destroyed. Larger compounds stick to the filter elements.

Catechin filter contains a natural antiseptic contained in tea leaves. Destroys 98% of all known viruses.

Wasabi filter disinfects air masses with the help of a specific substance contained in horseradish. Possesses a powerful bactericidal effect.

Filtration with silver ions destroys the internal structure of bacteria and absorbs their cells. Thus, microorganisms disappear completely or significantly reduce activity. The Nano Silver element is responsible for the constant production of ions.

Biofilter - a novelty in the production of air-conditioning units with air purification. Beneficial microbes live inside the cartridge, recycling 99% of dust and microorganisms.It consists of a prefilter for antibacterial treatment and large particles retaining, a bioderating filter to eliminate odors, an air filter that kills fungi, mold, and retains small particles.

Formaldehyde filter removes harmful volatile compounds, in particular formaldehyde, and unpleasant odors.

The premium air handling units are equipped with ionizers... Ionized air improves health, relieves fatigue, and helps to normalize metabolism. The room is kept fresh and clean for a long time. These air conditioners are ideal for children's rooms and for people suffering from chronic respiratory diseases.

In budget models, antioxidant filters are often installed, as well as those containing vitamin C.

Maintenance of air conditioners with air purification function

The electrostatic filter screen should be cleaned twice a month with active use. The frequency depends on the purpose of the room and the number of people who are constantly in it. Cleaning methods:

• a vacuum cleaner;
• rinsing with water.

You need to wash in warm water with non-aggressive detergents. Reinstall only after complete drying. Forced drying is prohibited, as the mesh deforms under the influence of hot air.

Fine filters do not need to be washed. The carbon cartridges are changed every 3-4 months.

After clogging, the photocatalytic filters are placed in direct sunlight. Deodorant ability is restored by 95%. The service life of such a filter is 5 years.

Many models of air conditioners have a filtration status indicator. It signals when a cartridge needs to be replaced. However, the sensor does not respond to actual contamination, but to an approximate lifespan, which is typically 2-3 months.

Examples of models from famous brands

Electrolux EASM-12 - floor air conditioner with air purifier. Works in ionization mode and provides antibacterial filtration. Works with low noise. Easily moves around the room. Not suitable for large areas. The cost of the model is about 30 thousand rubles.

Midea MSE-18HR - a model with a four-layer filter and a self-cleaning function, thanks to which the cartridge is replaced every five years. Works quietly. The price is 20 thousand rubles.

Toshiba Daiseikai N3KVR - provides two-stage plasma and photocatalytic filtration, contains an air ionizer. The self-cleaning function prevents moisture and mildew from accumulating in the indoor unit. Inverter control allows you to reduce the level of electricity consumption. It costs about 50 thousand rubles.

General Climate GC / GU-F10HRIN1 - equipped with a silver ion filter, bio-filter and air ionizer. The status indicator of the indoor unit informs about the need to replace the cartridges. Turbo mode allows you to set the required temperature in a short time. There is an automatic restart function in case of a sudden power outage.
