摘要

The process comprises causing the air to circulate in contact with or through a cassette-type container holding an agent that removes pollution and/or odors and adds a perfume. The agent consists of a porous base of chalk, clay or potassium permanganate, containing 0.5-90 wt.% of calcium peroxide to extract pollutants. The perfume is added by a micro- or macro-porous substance impregnated with an essential oil or solution and an optional bactericidal or fungicidal product.
