Abstract (en)
[origin: US4410339A] An air washing apparatus consisting essentially of two separate cyclic units. In the first cyclic unit, air is sprayed with a fluid consisting of water and a halogen. The spray removes impurities from the air, and brings the impurities into the fluid supply from which the impurities are removed in the second cyclic unit, by treating the fluid with ozone. After treatment, the fluid is returned to the fluid supply where the halogen in the fluid supply removes any ozone present, and thereby renders the fluid safe.
