The inventive device operates as follows.

The device is installed indoors and fixed on the wall so that the receiving hole 2, located in the housing 14, coincides with a previously made hole in the wall that connects the room to the street. A sealing ring with insulating material, which is a structural element of the body, is tightly adjacent to the wall and thereby prevents the possibility of a "temperature bridge".

The control unit 13, when the device is turned on, drives the asynchronous motor 17 and opens the shutter 24. The fan unit 10, consisting of an asynchronous motor 17 and fan impeller 11, creates a pressure difference due to which air from the street passes through the hole in the wall and the intake hole 2 getting inside the device. Then the air passes through a rough cleaning through filter 5, fine cleaning through a filter 6, filtering from odors through a charcoal filter 8, as well as volatile organic compounds using a photocatalytic filter 7. After that, the cleaned air enters the room through the outlet 12. If on the control unit 13, when the temperature is set higher than the temperature of the incoming air, a ceramic heater 9 is switched on automatically, raising the temperature of the incoming air to the required level.

The housing of the device 14 is made in a rectangular shape with a sequential arrangement of all elements. High quality air treatment is achieved through several cleaning levels through filters 5, 6, 7 and 8, a ceramic heater, as well as an integrated ultrasonic humidifier consisting of a piezoelectric emitter 21, tube 20, nozzle 19, water level sensor 22, centrifugal fan 26 and ultraviolet lamp 29.
