The Tier1 DPFS16x28x6M11 is a 2-pack of pleated HVAC air filters with nominal dimensions of 16" x 28" x 6" (actual size approximately 15.5" x 27.5" x 5.88"). It carries a MERV 11 rating, making it effective at capturing particles as small as 1-3 microns, including pollen, dust mite debris, mold spores, pet dander, and fine dust. This rating offers superior filtration compared to standard MERV 8 filters while maintaining good airflow in residential HVAC systems.

The Tier1 DPFS16x28x6M11 MERV 11 filter is designed to last 6 to 12 months under typical residential conditions, significantly longer than standard 1-inch filters. Since this is a 2-pack, you get up to 2 years of filtration coverage. Actual lifespan depends on factors such as household occupancy, presence of pets, local air quality, and HVAC runtime. We recommend inspecting the filter every 3 months and replacing sooner if it appears heavily loaded with debris.

The Tier1 DPFS16x28x6M11 is engineered as a direct replacement for Space-Gard and Aprilaire-style 6-inch deep media air cleaner cabinets that accept 16x28x6 filters. It fits whole-house HVAC air cleaner housings commonly installed on furnaces and central air systems requiring this specific size. Always verify your cabinet's required filter size before ordering to ensure proper fit and sealing.

The Tier1 DPFS16x28x6M11 features high-capacity synthetic pleated media supported by a sturdy beverage-board frame that resists moisture and warping. The deep 6-inch pleated design provides a large surface area, which allows for excellent dust-holding capacity, extended service life, and low pressure drop to protect your HVAC system from strain. The reinforced construction maintains structural integrity throughout the filter's service life.

Yes, the MERV 11 rating of the Tier1 DPFS16x28x6M11 makes it an excellent choice for households with allergy or asthma sufferers. It captures up to 85% of airborne particles in the 1-3 micron range, including pollen, pet dander, mold spores, smoke particles, and fine dust that can trigger respiratory issues. For best results, run your HVAC system's fan continuously or in circulation mode to maximize air turnover through the filter.
