ABSTRACT:
An air purifying and moistening device comprises a suction section having an air entrance opening, filter means at said opening and a motor-driven fan, an air purifying section including at least an ultraviolet radiation sterilization lamp, and a water ducting section within which the sterilized air is brought into contact with the water surface before it is discharged into the room. The water supply is a water trough or water tray with a large surface area of substantially stagnant water volume, which trough or tray is covered with a removable cover plate at a distance above the water surface. A casing forms a substantially closed air passage channel part of which is formed within said housing and another part of which is formed by the water surface, the lateral walls of the trough and the cover plate above said water surface. The exit-side of the air passage channel is formed as an air exit opening of said trough, which is restricted by said cover plate at the top, by the lateral walls at both sides, and by the front wall of the trough at the bottom.
