Designed to work with your heating and cooling systems and enhances the air in every room, capturing particles and other allergy-aggravating irritants. Conventional filters capture pollutants mainly by trapping larger particles on the filter surface, which restricts airflow. The Lennox model #5423 draws particles as small as .3 microns deep inside the filter, allowing maximum airflow and filtration efficiency. The results are cleaner air, lower utility bills and longer filter longevity.
