AprilAire 16 in. W X 25 in. H X 4 in. Synthetic Fiber 11 MERV Pleated Air Cleaner Cabinet Air Filter

Upgrade your indoor air quality with the AprilAire 16x25x4 Synthetic Fiber 11 MERV Pleated Air Cleaner Cabinet Air Filter. Engineered to fit AprilAire cabinet air cleaners, this pleated filter uses durable synthetic fiber media and a robust metal mesh support to deliver dependable filtration without sacrificing airflow.

At an 11 MERV rating, it effectively captures a broad range of common indoor pollutants—bacteria, pollen, dust, and mold spores—helping to reduce allergy symptoms and keep your living spaces fresher. Note: this filter is designed to address these particles and does not filter smoke or viruses. For smoke or virus-specific concerns, consider complementary filtration strategies in your broader air quality plan.

The design prioritizes both filtration efficiency and longevity. The pleated media increases surface area for more responsive filtration, while the metal mesh support prevents sag and maintains a tight seal within the cabinet. This combination helps extend the filter’s life and maintain consistent air flow through your system.

Designed for a precise, customizable fit, this filter is trimmable to align with your cabinet’s exact dimensions while preserving the integrity of the filtration media. It’s sold as a single unit and is ideal for homes, offices, and other spaces that use AprilAire cabinet air cleaners with 16x25x4 framing.
