Lennox X0445 Media Filter

The Lennox X0445 is a high-efficiency Healthy Climate replacement media filter designed for use in the PMAC-20C series air cleaner. This MERV 11 pleated filter provides a significant upgrade over standard fiberglass filters, utilizing an expandable accordion-style design to maximize surface area and minimize static pressure across the HVAC system. At a nominal size of 25x20x6, the X0445 effectively captures airborne contaminants such as dust, pollen, mold spores, and pet dander down to 0.3 microns without compromising airflow performance. This part is a direct OEM match for the X044501 and serves as a verified furnace filter replacement for the Aprilaire/Spacegard 201 media used in 2200 and 2250 housings. For field technicians, the Lennox X0445 media filter ensures a precise fit and robust filtration, maintaining indoor air quality while protecting sensitive blower components from debris buildup. Its synthetic construction and electrostatically charged fibers provide consistent particle capture throughout its service life in residential or light commercial applications.
