The Tier1 DPFS20X25X6M11-2PK is a 2-pack of pleated media air filters with nominal dimensions of 20" x 25" x 6" (actual size approximately 19.5" x 24.5" x 6"). It carries a MERV 11 efficiency rating, making it ideal for capturing particles as small as 1-3 microns, including pollen, dust mites, mold spores, pet dander, and fine dust. This filter is designed as a direct replacement for whole-house media air cleaners such as Aprilaire 201, Space-Gard 2200, and similar 6-inch deep pleated filter housings.

The Tier1 DPFS20X25X6M11-2PK is engineered to last up to 12 months under typical residential conditions, though replacement every 6-9 months is recommended for homes with pets, allergy sufferers, or higher dust levels. Since this product comes as a 2-pack, you receive a full 2-year supply of filtration. Regular replacement maintains optimal airflow through your HVAC system and ensures consistent MERV 11 particle capture efficiency.

Yes, the Tier1 DPFS20X25X6M11-2PK is specifically designed to fit Aprilaire/Space-Gard models 2200, 2250, and other whole-house media air cleaners that require a 20x25x6 filter. It is a cost-effective replacement for Aprilaire 201 OEM filters. The deep 6-inch pleated design provides significantly more surface area than standard 1-inch filters, resulting in better dust-holding capacity, lower pressure drop, and longer service life.

With its MERV 11 rating, the Tier1 DPFS20X25X6M11-2PK captures a wide range of airborne particulates including pollen, dust, lint, mold spores, pet dander, smoke particles, smog, and fine dust down to 1 micron. The electrostatically charged synthetic media enhances particle capture efficiency while maintaining strong airflow, helping improve indoor air quality for allergy and asthma sufferers without overworking your HVAC blower.

No. The Tier1 DPFS20X25X6M11-2PK features a deep 6-inch pleated design with expanded surface area specifically engineered to provide MERV 11 filtration without creating excessive static pressure. This deep-pleat construction allows the filter to capture more particles while maintaining proper airflow through your whole-house media air cleaner. For best performance, ensure the filter is installed with the airflow arrow pointing toward the blower and inspect it periodically for loading.
