The Tier1 DPFS16X28X6M11DLX-2PK is a 2-pack of deep-pleated replacement air filters with nominal dimensions of 16" x 28" x 6" (actual size typically 15.5" x 27.5" x 6"). These filters carry a MERV 11 rating, making them effective at capturing particles as small as 1–3 microns, including pollen, dust mites, pet dander, mold spores, and smoke particles. They are designed as a direct replacement for media air cleaners such as Lennox X0583, Honeywell FC100A1011, and similar whole-house systems.

Each Tier1 DPFS16X28X6M11DLX deep-pleated filter is engineered to last 6 to 12 months under normal residential conditions, depending on indoor air quality, pet presence, HVAC runtime, and household dust levels. Since this is a 2-pack, you receive up to 2 years of filtration coverage. Homes with pets, smokers, or allergy sufferers may need to replace the filter closer to the 6-month mark for optimal performance.

This Tier1 filter is a cross-reference replacement for multiple OEM media filters, including Lennox X0583, Honeywell FC100A1011, Carrier FILXXCAR0016, Bryant, Day & Night, Payne, and General Aire 14161. It fits media air cleaner cabinets designed for 16x28x6 deep-pleated filters. Always verify your current filter's actual dimensions before ordering to ensure a proper seal within your air cleaner housing.

With its MERV 11 efficiency, the Tier1 DPFS16X28X6M11DLX captures 65–85% of airborne particles in the 1.0–3.0 micron range and over 85% of particles 3.0–10.0 microns. This includes pollen, dust, lint, mold spores, pet dander, dust mite debris, smog, and auto emissions. The deep 6-inch pleated design offers more surface area than standard 1-inch filters, resulting in better airflow, longer service life, and reduced strain on your HVAC blower.

To install, turn off your HVAC system at the thermostat. Open the media air cleaner cabinet door and slide out the old filter, noting the airflow direction arrow. Insert the new Tier1 DPFS16X28X6M11DLX filter with the airflow arrow pointing toward the blower/furnace. Ensure the filter seats fully against the gasket to prevent air bypass. Close the cabinet, record the installation date on the filter frame, and restore power. No tools are required for this replacement.
