Abstract
An air filter for use with wood or coal stoves of the type having a plenum surrounding the firebox. The air filter includes a porous framework in the shape of a C-shaped channel which houses a filter pad. The outer and inner surfaces of the framework are porous and substantially open. The framework is preferably of a relatively stiff, but deformable, open weave material bounded along its edges by a circumferential frame. The inner surface defines an access opening through which the filter pad can be inserted. The air filter is sized to cover a recirculating air inlet of the stove. Magnetic strips allow the air filter to be easily and quickly mounted to the stove without modification.
Claims4
An air filter for covering a recirculating air inlet of a stove, at least a portion of the region of the stove defining the air intake being a ferrous metal, the air filter comprising:
- an elongate, C-shaped channel framework having a substantially porous outer surface, an inner surface, lateral sides and open ends, said inner surface having spaced apart, parallel, solid edges defining an open area extending the length of said inner surface, the portions of said framework defining said open ends being solid, said outer surface, said inner surface and said lateral sides having the same length, said outer and inner surfaces having the same width and said lateral sides having the same depth;
- a generally flat filter pad housed within said framework;
- and
- a pair of spaced-apart elongate magnetic strips mounted to said parallel, solid edges, said magnetic strips extending substantially the entire length of said inner surface for fastening the air filter to cover the air intake of the stove.
