Frequently Asked Questions

What are the exact dimensions and specifications of the Tier1 DPFS20X25X6DLX 2-Pack air filter?

The Tier1 DPFS20X25X6DLX is a deluxe pleated furnace and HVAC air filter with nominal dimensions of 20" x 25" x 6" (actual size approximately 19.88" x 24.75" x 6"). This 2-pack is designed as a replacement for whole-house media air cleaners and features a heavy-duty beverage-board frame with a high-capacity pleated synthetic media designed to maximize dust-holding capacity while maintaining low airflow resistance in your HVAC system.

What is the MERV rating of the Tier1 DPFS20X25X6DLX and what does it capture?

The Tier1 DPFS20X25X6DLX carries a MERV 11 rating, which captures airborne particles as small as 1 micron. At this efficiency level, the filter traps dust, pollen, pet dander, mold spores, lint, dust mite debris, and smoke particles. This makes it an excellent choice for households with allergy sufferers or pets, delivering cleaner indoor air without over-restricting airflow through your furnace or air handler.

How often should I replace the Tier1 DPFS20X25X6DLX filter?

The Tier1 DPFS20X25X6DLX is engineered for long-lasting performance and should be replaced approximately every 6 to 12 months under normal residential use. Since this 2-pack includes two filters, you get a full year or more of filtration coverage. Homes with pets, smokers, high dust levels, or ongoing construction may need to replace the filter closer to the 6-month mark for optimal HVAC efficiency and indoor air quality.

Which HVAC systems and OEM filters is the Tier1 DPFS20X25X6DLX compatible with?

The Tier1 DPFS20X25X6DLX is a direct replacement for several popular whole-house media air cleaners, including Honeywell FC100A1037, Lennox X6673, Carrier FILXXCAR0020, Bryant, Payne, and Day & Night media cabinets that use a 20x25x6 filter. Always verify the actual filter dimensions of your current filter before ordering to ensure a proper fit in your media cabinet housing.

Does the Tier1 DPFS20X25X6DLX require a specific orientation during installation?

Yes, the Tier1 DPFS20X25X6DLX must be installed with the airflow arrow printed on the filter frame pointing in the direction of airflow—toward the furnace or air handler blower. Incorrect orientation reduces filtration efficiency and can cause the pleats to collapse under airflow pressure. Slide the filter into the media cabinet with the arrow facing the correct direction, then secure the cabinet door to ensure an airtight seal for maximum performance.
