摘要

An arrangement for filtering and moistening air comprises an air-mist mixer (6) connected to an atomizer (5) in the air stream of the air to be cleaned and a foaming device (8) arranged in front of the outlet of the housing (1) of the arrangement. The foaming device contains platinum or copper as a catalyst. The dwell time and contact time of the air-mist stream in the foam and with the catalyst surface of the foaming device is measured so that hydrogen peroxide is completely decomposed up to the outlet of the housing.
