These products are devices for effective cleaning of the supply (sometimes extract) 
air indoors. Depending on the nature of pollution and the specified parameters of air purity the design of the ventilation filters is subject to change. According to the degree of filtration, the products are classified into the following types:
G3-G4 coarse filters (from 10 microns);
F5-F9 fine filtration (from 1 micron);
HEPA ultrafine cleaning (up to 0.1 microns).
A fabric made of synthetic fibers or a metal mesh is used as a filter material in coarse cleaning products. 
The structure can be in the form of cells (panels), corrugated cloth, etc. Fiberglass is used in products with a fine filtration degree. Structurally, these filters
can be made in the form of folded or pocket products.
