A white Thesslagreen ventilation unit sits in front of a wall-mounted duct run that passes through an open purifier housing and the "Nawilżacz V3 Humidifier", whose open case shows white cartridges. White plastic ducts with bends continue across the wall, and a visitor reads a leaflet beside a screen on the white stand.
