FIELD: air purification.
SUBSTANCE: inventions group relates to the field of air purification by means of electrostatic devices. The device includes a metal case, in which at least one air intake hole and at least one air outlet hole are made. An electrical circuit is located inside the housing, including at least a fan, an electronics unit and an electrostatic unit, a pre-filter, at least one adsorption-catalytic filter, and at least one precipitator filter. The adsorption-catalytic filter and the filter-precipitator are made in the form of hollow cylinders, one of the ends of which is made closed. The filter-precipitator is located inside the adsorption-catalytic filter. The electrostatic block is located perpendicular to the air flow, and the precipitator is located in such a way that its axis is parallel to the air flow.
EFFECT: efficient purification of the air from the foreign large and small particles contained in it, such as dust and aerosols, is provided, and the accumulation of an electrostatic charge in the device case is prevented.
