Abstract:
1. A fireplace including an air filter, the fireplace comprising: a combustion chamber enclosure having at least top, bottom and rear panels and defining a combustion chamber for the combustion of fuel; an outer enclosure including a plurality of panels that define an inner volume sized to receive the combustion chamber enclosure, the plurality of panels being positioned relative to the enclosure to form a plenum defining an air passage that extends around an outer surface of at least the top, bottom and rear panels of the combustion chamber enclosure, the air passage having an air intake into the air passage and an air exhaust out of the air passage; and a filter disposed within the air passage below the combustion chamber to limit the exposure of the filter to heat generated in the combustion chamber; wherein the fireplace is configured for the flow of intake air into the air passage through the air inlet thereby causing the intake air to pass through the filter to remove airborne contaminants from the intake air, and is configured for exhausting the filtered intake air out of the air passage through the air exhaust.
