The Tier1 MERV 8 16x25x1 air filter has nominal dimensions of 16" x 25" x 1" and actual dimensions of approximately 15.5" x 24.5" x 0.75". This pleated filter is designed as a direct-fit replacement for standard 16x25x1 HVAC systems, furnaces, and air handlers. Always verify your system's required filter size before ordering to ensure a proper fit and optimal airflow.

The Tier1 MERV 8 16x25x1 filter is rated to capture particles between 3.0 and 10.0 microns, including household dust, pollen, dust mites, lint, mold spores, and pet dander. With its MERV 8 rating, it provides reliable whole-home air filtration suitable for most residential HVAC systems without restricting airflow. For allergen or smoke reduction, consider upgrading to a higher MERV-rated Tier1 filter.

Tier1 recommends replacing the MERV 8 16x25x1 pleated air filter every 90 days under normal conditions. However, homes with pets, smokers, or high dust levels may need to replace it every 30–60 days. Regular replacement maintains HVAC efficiency, reduces energy costs, and ensures consistent indoor air quality throughout your home.

The Tier1 MERV 8 rating is equivalent to a MPR 600 and FPR 5 rating, making it a solid mid-tier filtration option. It captures up to 90% of large airborne particles 3.0 microns and larger. This MERV 8 filter is ideal for standard residential use, balancing efficient particle capture with low airflow resistance to protect your HVAC blower motor.

The Tier1 MERV 8 16x25x1 pleated filter is compatible with virtually any HVAC system, furnace, or air handler that uses a standard 16x25x1 filter slot. Its electrostatically charged synthetic media and beverage-board frame provide rigid support for consistent performance. Check your existing filter's nominal size printed on the frame to confirm compatibility before purchasing.
