The Lennox 52W41 is a genuine OEM 20" x 25" x 2" pleated air filter built to provide superior filtration efficiency compared to standard fiberglass filters, capturing finer particles including dust, mold spores, and pollen. A dirty or expired pleated filter restricts airflow, reduces system efficiency, and can cause your Lennox system to overheat or short-cycle. Replace this filter on a regular maintenance schedule to protect your Lennox HVAC equipment and maintain healthy indoor air quality.
