ABSTRACT:
An air filtration system for a cooking stove collects exhaust air from the stove with a vent hood, filters grease, particles and odors from the exhaust air and returns the filtered exhaust air to the room in which the stove is used. Exhaust air is cleansed of particles and odors by an activated charcoal filter within a return air conduit leading from the vent hood to the room. An electrically operated fan draws exhaust air into the vent hood, through grease filters and the activated charcoal filter and forces exhaust air back into the room. Regeneration of the activated charcoal filter is provided at selective intervals of time to maintain the effectiveness of the charcoal, and cooling of return air is provided for.
