Abstract (en)

[origin: WO0126781A1] The object of the invention is a method and device for processing indoor air. According to the invention, the air is directed in the form of air jets (a) against the surface (3a) of a liquid (3), such as water. The direction of the air is preferably implemented near the liquid surface (3a) as air jets (a) essentially perpendicular to the liquid surface (3a). In this way, detrimental ingredients, such as detrimental particles can be removed from the air. When water is used as the liquid, it is also possible to moisten or dry the air that is processed.
