Filters in air conditioners and their features

When choosing an air conditioner, it is important to take into account not only its power, but also what filters it is equipped with. The complete set of climatic equipment usually includes a whole set of filters to solve different tasks.

The most advanced models of air conditioners are equipped with purification systems that rid the air of almost all types of impurities, among the main ones:

• tobacco smoke;
• dust;
• poplar fluff;
• mold spores;
• microbes, including pathogenic ones;
• pet hair;
• toxic substance.

The quality of the filter affects the cost of the air conditioner. An expensive universal model is not always the best solution. The Sensei company recommends that when choosing a unit, take into account what types of contamination prevail in each particular case. In damp rooms, the priority will be to remove fungal spores, in the living room to clean the air from dust, in the production shop from toxic substances, etc.

Rough cleaning

The most important part of the filter set, which works as a sieve and gets rid of 95% of coarse dust, wool and down. Increases the service life of climate control equipment. It does not allow clogging of the split system itself, since dust larger than 2 microns does not enter the heat exchanger.

Mechanical filters themselves require periodic cleaning. You can find out about their status by using a special indicator. Its activation occurs on average once every 2 months, when the filter needs preventive maintenance and cleaning from accumulated dirt. In modern air conditioners, coarse filters should be cleaned at a frequency of 1-2 times a year.

Fine filtration

Filters that eliminate dust, bacteria, and various impurities up to 1 micron in size can have a base: carbon or polymer. As working tools can be used: ultraviolet, plasma technologies, electrostatic interaction. If there are several different filters in one unit, then the price of such a device is higher than the average.

Carbon filter. They contain activated carbon. They have a deodorizing effect, as they remove sources of unpleasant odors. They last up to 5 months. Their durability depends on a number of factors, including the main ones:

• environmental situation in the region;
• the proximity of motorways;
• the building’s location relative to the cardinal directions.

Zeolitic based on a porous mineral, excellent adsorbent. More efficient than coal-fired ones. They will last up to 5 years if periodically washed with clean water.

Electrostatic. They are based on the interaction of differently charged particles. They have an unlimited service life.

Plasma, destroying the spatial structure of toxic compounds, the structure of mold fungi, bacteria. They work for an unlimited time. Get rid of allergens.

Ultraviolet filters with an led light that disinfects the air and destroys viruses and bacteria.

Photocatalytic with titanium dioxide as a catalyst that accelerates the decomposition reactions of unsafe organics. They cope with both organic and mineral contamination. They work for a long time, as long as the functionality of the UV lamp is preserved.

Biofilters inactivate the microorganisms. The basis can be:

• Wasabi. It is obtained from a plant growing in the North of Japan and has bactericidal properties. Wasabi-filter removes formaldehyde, neutralize mites.
• Catechin is a natural antiseptic found in apples and green tea.

Filters containing flavonoids, have an antioxidant effect, that is, they destroy free radicals.

Filters with ascorbic acid. Manufacturers claim that vitamin C boosts the immune system and improves skin condition. Some experts believe that this is a marketing move aimed at increasing sales of budget air conditioners.

ULTRA Hi Density

A new generation filter that removes more than 90% of pollutants from the air, including dust, pathogenic microbes and toxic substance molecules. It has microcells for better air purification. A multi-layer filter with a special coating, created according to the latest technologies, copes with allergens, various organic compounds. It is found in the most advanced models of climate technology from the most advanced manufacturers.
