The equations of multiple regression of air quality from factors affecting external sources of emission in the urban environment are obtained. A prototype of a forced air supply ventilation valve with air purification, placed in the outer wall of the building, using various sorbents together with a photocatalytic filter (a thin porous plate coated with titanium dioxide next to two UV lamps, UV-A range, 365 nm, 6 W each) was developed. Full-scale studies of five options for purifying the supply air were carried out. High quality of outdoor air purification from pollutants has the following options: shungite; zeolite; silica gel; photocatalytic filter, its purification efficiency was 96.39-99.98% for carbon oxide (II), 96.39-97.89% for phenol, 95.76-97.78% for formaldehyde, and 93.97-95.12% for aliphatic hydrocarbons (C1-C5). The results obtained can be used in multi-storey construction.
