The Tier1 DPFS16x28x6M11DWR-2PK is a 2-pack of pleated air filters with nominal dimensions of 16" x 28" x 6" (actual size typically 15.5" x 27.5" x 6"). It carries a MERV 11 rating, meaning it captures airborne particles as small as 1-3 microns, including pollen, dust mites, pet dander, mold spores, and fine dust. This makes it an ideal upgrade for allergy sufferers without restricting airflow in your HVAC system.

The Tier1 DPFS16x28x6M11DWR filter is designed to last up to 12 months under normal residential conditions, thanks to its deep 6-inch pleated media with extended surface area. Since this SKU comes in a 2-pack, you get up to 2 years of filtration coverage. Homes with pets, smokers, or high dust levels may need replacement every 6-9 months for optimal HVAC performance.

This Tier1 filter is engineered as a direct replacement for whole-house media air cleaners requiring a 16x28x6 filter, including select Aprilaire, Lennox, Honeywell, and Bryant/Carrier housings that accept this size. Always verify your cabinet's actual filter slot dimensions before ordering. The pleated galvanized steel-free beverage board frame provides rigid support to prevent bowing or air bypass inside the cabinet.

Yes. With its MERV 11 electrostatically charged synthetic media, the DPFS16x28x6M11DWR captures up to 85% of particles in the 1-3 micron range and over 90% of particles 3-10 microns. This includes common allergens like pollen, pet dander, dust mite debris, and mold spores, making it an excellent choice for households with allergy or asthma concerns. For even higher filtration, Tier1 also offers MERV 13 options in the same size.

No. The deep 6-inch pleat design of the DPFS16x28x6M11DWR provides significantly more surface area than 1-inch filters, which allows for high dust-holding capacity with low initial pressure drop. This means your HVAC blower doesn't have to work harder, helping maintain energy efficiency and system longevity while still delivering MERV 11 filtration performance throughout its 12-month service life.
