Abstract
An air cleaner for use in a central heating and air conditioning system for a home or small building has a hollow shell that is configured to fit into the duct system associated with the heating and air conditioning system such that all or substantially all the air heated or cooled by the unit passes through the shell. Located in the shell is an ozone generator and an activated carbon filter. The activated carbon filter is located downstream of the ozone generator and substantially all of the heated or cooled air passes through the activated carbon filter. The activated carbon filter is sized to absorb a substantial portion of the ozone generated by the ozone generator.

An air cleaner for use in a central heating and air conditioning system comprising:
- (a) A hollow shell that is configured to be placed into a heating/air conditioning system in a manner such that a substantial portion of the air that is heated or cooled by the heating/air conditioning system passes through said shell;
- (b) An ozone generator that is located in said shell;
- (c) An activated carbon filter that is located in said shell downstream of said ozone generator;
- wherein
- (d) Substantially all of the air that is being heated or cooled passes through said activated carbon filter;
- and
- (e) Said activated carbon filter is sized to absorb a substantial portion of the ozone generated by said ozone generator.
A method for cleaning air that passes through a central heating and air conditioning system, comprising:
- (a) Placing an ozone generator in a duct through which air from said heating and air conditioning system passes;
- and
- (b) Placing an activated carbon filter in said duct downstream of said ozone generator, said activated carbon filter being sized to absorb between 50 and 90 percent of the ozone generated by the said ozone generator.
