<p>Apparatus (10) for purifying indoor air comprises a blower (14) for circulating air through a duct and removing particles and neutralizing a number of harmful gases through a process of molecular catalytic cracking of heavy hydrocarbons at ambient temperatures. Preferably, the apparatus includes a series of treatment elements including an ozone generator (20) for producing an oxidator gas, a bio-mass collector (24), a filter (26) coated with zeolite and surface modified hopcalite for removal of CO and NOx compounds, a filter (28) coated with calcium carbonate for removing carbon dioxide and hydrohalic compounds, a filter (30) coated with zeolite for solvents such as MEK and adsorbing water, and one or more filters (32, 34) for removing particulates in the air stream. The filters thus remove particulates and neutralize a number of harmful gases that may be present in indoor air.</p> |
