초록 ▼

A hood for directing smoke from a wood burning fireplace through a filter or catalytic converter enables a substantial reduction in pollutants released to the environment. In an exemplary embodiment, a hood includes a housing, in which an exhaust cleaner support unit supports an exhaust cleaner for reducing pollutants as smoke is directed from an intake opening of the housing to an exhaust opening of the housing. A rear surface of the housing and side surfaces of the housing abut three walls of the fireplace, reducing air paths behind or beside the hood to capture a substantial amount of the smoke from the fire. The front of the hood is tapered to direct the smoke toward the exhaust cleaner. Due to a mild suction effect from heating of the exhaust cleaner, the front surface of the hood need not extend all the way to the front of the fireplace, and air flow in front of the hood into the flue is not impeded.

1. An air pollution reduction unit comprising: a hood having an open top and an open bottom, the hood comprising a front surface,a rear surface, andfirst and second opposing side portions connecting the front surface to the rear surface, the bottom of the hood defining an intake opening;an exhaust cleaner support unit having an open top and an open bottom, the bottom of the exhaust cleaner support unit disposed on the top of the hood and the top of the exhaust cleaner support unit defining an exhaust opening; andfirst and second adjustable hood supports, each hood support extending from the first and second side portions, respectively. 2. The air pollution reduction unit of claim 1 wherein the front surface is inwardly tapered between the open bottom and open top of the hood. 3. The air pollution reduction unit of claim 1, further comprising first and second mounting brackets attached to the first and second extending arms, respectively. 4. The air pollution reduction unit of claim 3, wherein the first and second mounting brackets each comprise a ledge. 5. The air pollution reduction unit of claim 1, wherein the hood is an aftermarket unit configured to be installed in the fireplace. 6. The air pollution reduction unit of claim 1, further comprising a catalyst material for accelerating a chemical reaction to reduce the exhaust pollutants from the fireplace disposed in the exhaust cleaner support unit. 7. An air pollution reduction unit comprising: a hood having an open top and an open bottom, the hood comprising a front surface,a rear surface, andfirst and second opposing side portions connecting the front surface to the rear surface, where the bottom of the hood defining an intake opening;an exhaust cleaner support unit having an open top and an open bottom, the bottom of the exhaust cleaner support unit disposed on the top of the hood and the top of the exhaust cleaner support unit defining an exhaust opening; anda first flange at the exhaust opening, the first flange extending inwards toward the exhaust opening. 8. The air pollution reduction unit of claim 7, further comprising a second flange at the exhaust opening, the second flange extending outwardly from the exhaust opening. 9. The air pollution reduction unit of claim 7, wherein the side portions and the front surface are each tapered inward to form an upside-down funnel shape. 10. The air pollution reduction unit of claim 9, wherein the side portions and the front surface each extend downward from the exhaust cleaner support unit by about two inches.
