Frequently Asked Questions

What are the exact dimensions and MERV rating of the Tier1 DPFS20X25X6M11DLX filter?

The Tier1 DPFS20X25X6M11DLX is a 20x25x6 deep-pleated replacement air filter with a MERV 11 rating. Its actual dimensions are approximately 19.88" x 24.75" x 6", designed as a direct-fit replacement for whole-house media air cleaners such as the Lennox X0581, Honeywell FC100A1037, and Carrier/Bryant housings that accept a 20x25x6 cabinet filter. This 2-pack provides a full year of filtration when replaced on schedule.

How often should I replace the Tier1 DPFS20X25X6M11DLX deep-pleated filter?

Tier1 recommends replacing the DPFS20X25X6M11DLX every 6 months under normal residential conditions. Homes with pets, smokers, renovation dust, or seasonal allergies may require replacement every 3–4 months. Because this product ships as a 2-pack, you receive a full 12 months of whole-house air filtration, keeping your HVAC system running efficiently and maintaining consistent airflow through the media cabinet.

What contaminants does the Tier1 MERV 11 DPFS20X25X6M11DLX capture?

With its MERV 11 rating, the Tier1 DPFS20X25X6M11DLX captures airborne particles as small as 1–3 microns, including household dust, pollen, pet dander, mold spores, dust mite debris, smoke particles, and lint. The electrostatically charged, deep-pleated synthetic media provides higher dust-holding capacity than standard 1" filters, making it ideal for allergy sufferers and homes with forced-air heating and cooling systems.

Is the Tier1 DPFS20X25X6M11DLX a compatible replacement for Lennox, Honeywell, and Carrier media cabinets?

Yes. The Tier1 DPFS20X25X6M11DLX is engineered as a cross-reference replacement for Lennox X0581 / X6670, Honeywell FC100A1037, Carrier FILCCCAR0020, Bryant FILBBCAR0020, Trion Air Bear 255649-103, and other 20x25x6 whole-house media air cleaner cabinets. It drops directly into the existing housing—no modifications, adapters, or tools required—while delivering equivalent MERV 11 performance at a lower cost than OEM filters.

Will the MERV 11 rating of the DPFS20X25X6M11DLX restrict airflow in my HVAC system?

No. The Tier1 DPFS20X25X6M11DLX uses a 6-inch deep-pleated design with expanded surface area, which allows MERV 11 filtration efficiency while maintaining low static pressure. Compared to high-MERV 1" filters, this deep-pleat construction reduces strain on your blower motor, helps preserve energy efficiency, and supports consistent airflow throughout the full 6-month service life of each filter.
