AIR PURIFICATION FILTER AND METHOD ABSTRACT OF THE DISCLOSURE The invention provides an air purification filter for use in kitchens, restaurants, living areas and the like. The filter is provided in a housing having an inlet and an outlet for the air, the air preferably being driven through the interior of the housing by a fan. A microporous filter is provided in the housing, through which the air is constrained to pass. The microporous filter is directly electrically charged to one polarity and particles in the air are charged to the opposite polarity upstream of the filter so that they carry a charge when entering the microporous filter. The particles are thus attracted to, and deposited on, the interior surfaces of the microporous filter as the air passes therethrough. Hence, the filter traps even the minute particles that would normally pass through it.
