<p>APPARATUS AND METHOD FOR CLEANING AIR An apparatus and a method for cleaning air carrying smoke, grease, ordors and other pollutants. The air having the grease and other pollutants, such as the exhaust air from a restaurant cooking grill, is passed through a filter box in which is mounted two pairs of planar filter members. The air is passed sequentially in halves through a lower pair of the filter members and thence through an upper pair of the filter members and out of the filter box. The filter members are continuously scrubbed by a scrubbing solution comprising cold water and a cold water detergent. The water cools the air and grease in the air is congealed, and it acts as a filter, and it removes the congealed grease from the filter members.</p> |
