摘要

Room air filter arrangement (1) comprises units (65, 73) for sucking in and/or expelling air in a housing (3) and a unit (35) for producing a flat liquid stream (37, 39) acting as a filter in the flow path of the air inside the housing. Preferred Features: The unit for producing the flat liquid stream produces a fluid film and the flow path of the air passes through the fluid film. The fluid is water. The units for sucking in and/or expelling air in the housing are fans. A collecting device collects condensate which deposits on an outer surface of the housing.
