ABSTRACT:
An air filtering apparatus for purifying air. The air filtering apparatus includes an enclosure for coupling to ducting of a ventilation system. The enclosure has an interior defined by a top wall, a bottom wall, a pair of side walls, a first end wall, and a second end wall. A plurality of filters comprises a pair of wet filters and a pair of dry filters positioned in the interior. A pair of pump members supplies water from an enclosure reservoir to each of the wet filters. A supply assembly supplies water to the enclosure reservoir. A drain assembly drains the enclosure reservoir at preset intervals. A fan member forces exterior air through each of the filter members and outwardly through a duct aperture in the first end wall. A control assembly controls each of the pump members and the drain assembly to coordinate a purge sequence of the enclosure reservoir.
