The 16x20x4 deep-pleat MERV 8 air filter packs extra filtration surface into a 4-inch frame, capturing dust, pollen, lint, dust mites, and mold spores while keeping airflow free-flowing. Its depth means fewer changes — typically every 6 to 12 months. Fits 4-inch filter cabinets and media air cleaners. Available as a single unit or case pack.
