Breathe easier with the advanced filtration power of the Lennox X5422 20x26x3 MERV 11 Replacement Pleated Air Filter. This factory-original replacement is designed to support optimal performance in your Lennox PureAir PCO-20U system. With a MERV 11 rating, this high-efficiency filter captures particles as small as 0.3 microns - including allergens like dust mites, pollen, mold spores, and pet dander - making your indoor air cleaner and healthier. Its synthetic pleated media is engineered for a large surface area, which boosts dirt-holding capacity while minimizing airflow resistance. Built to match OEM specifications, the filter offers a snug fit and dependable performance. Though it can last up to a full year, replacement needs may vary based on your household conditions. The Lennox X5422 Pleated Air Filter is a smart and effective choice for maintaining air quality without sacrificing system efficiency.
