How to choose an air purifier for an apartment: important points
An indispensable device in urban environments can be an air purifier for an apartment. Which device to choose from a wide range of products, an ordinary consumer can hardly say. In connection with the relevance of the topic, it is proposed to consider the basic principles on which the choice should be based.

The main types of filter elements
The most important components of devices designed to remove negative impurities from air masses are filters. The cleaning efficiency largely depends on their type. The most popular are the following varieties.
Mechanical
Mechanical filters are mainly used for pre-cleaning air streams. They are able to trap dust particles, organic and inorganic fibers, animal hair. Most often they are used to protect the internal parts of devices.
In this case, a polymer mesh, foam rubber or special fabric is used as a filter element. If the barrier for the penetration of large particles is not cleaned in time, then its effectiveness is reduced to zero. To remove dirt, you can use normal or washing vacuum cleaner.
Coal
In most cases, these filters are used as additional elements in cleaning systems. They cannot effectively trap light compounds, but they are capable of trapping unpleasant odors, gas impurities, esters, phenols and formaldehydes.
The principle of operation of the filters is that the molecules of substances are adsorbed directly on the activated carbon. However, different particles can be absorbed in different ways. Some are worse and some are better.
As it gets dirty, it is necessary to replace the filter parts. Their service life can vary within 3-12 months. You can buy an air purifier for an apartment with a charcoal filter for a relatively low price. However, they are more often used in combination with other analogs.
Electrostatic
Electrostatic structures are highly efficient. They perfectly clean the air from soot and dust, but not from toxic substances and volatile organic compounds. The filters are based on the principle of collision of charges of two polarities.
During operation, voltage is applied to the block consisting of metal plates. It makes it possible to form an electrostatic field. Dust as it passes between these plates is attracted to them. The filters are capable of capturing particles larger than 0.01 microns, so they are excellent for use in air purifiers from dust.
HEPA filters
The products are manufactured on the basis of branched-pore borosilicate fiberglass. They trap 85 to 95 percent of pollutants. As for the advanced analogs of TRUE HEPA, they help to clean the air by 99 percent.
Due to their high efficiency, the presented filters are widely used in medicine, industry and electronics. Of the significant disadvantages for consumers, one can single out the high cost of products.
Photocatalytic
Filtration uses a completely new technology called photocatalysis. Harmful impurities of organic origin do not remain inside, but decompose under the influence of ultraviolet radiation and titanium dioxide. As a result, harmless components are formed.
Photocatalytic filters are capable of breaking down the smallest particles that can only be compared with large molecules. The cleaning efficiency is not affected by the period of operation of the filter element, since there is no period of use.
How to choose an air purifier for an apartment: basic rules
An effective solution for living in a polluted city environment is an air purifier for an apartment. Every resident of a metropolis should know which device to choose from the whole variety of existing models, especially if the ecological situation in a particular region is not at a high level.

Summarizing
Within the framework of the article, it was considered which air purifiers are chosen for apartments and what should be considered when purchasing. However, you should not forget about the design possibilities. Devices should successfully fit into the overall interior, because in the conditions of modern life, aesthetic characteristics are highly valued.
