This filter is designed to work with your heating and air conditioning unit removing particulates from the air stream, protecting your equipment and your health. Conventional filters capture pollutants mainly by trapping larger particles on the filter surface, which restricts airflow. The Lennox X1152 filter draws particles as small as .3 microns deep inside the filter, allowing maximum airflow and filtration efficiency.
