The Tier1 16x20x1 air filter carries a MERV 13 rating, which is equivalent to FPR 10 and MPR 1500–1900. This high-efficiency pleated filter captures up to 90% of airborne particles as small as 1 micron, including dust, pollen, pet dander, mold spores, smoke, smog, bacteria, and virus carriers. It's an ideal choice for households with allergy sufferers or pets seeking improved indoor air quality without restricting HVAC airflow.

The nominal size is 16x20x1 inches, while the actual dimensions measure 15.5" x 19.5" x 0.75" to ensure a snug fit inside standard HVAC return vents and furnace slots. Each filter in this 6-pack features a beverage board frame with synthetic electrostatic pleated media, providing more surface area than flat panel filters for extended dust-holding capacity and longer service life.

Tier1 recommends replacing this 16x20x1 air filter every 90 days (3 months) under typical residential conditions. Homes with pets, smokers, frequent HVAC use, or occupants with allergies should inspect the filter every 30–60 days and replace it sooner if loaded with debris. With this 6-pack, you receive an 18-month supply, simplifying your maintenance schedule and ensuring year-round clean air.

No, despite its MERV 13 efficiency, the Tier1 16x20x1 pleated filter is engineered with high-loft electrostatic media and deep pleats to maintain optimal airflow. The pleated design increases surface area, reducing static pressure compared to dense flat filters. This allows your furnace or AC to operate efficiently while still delivering hospital-grade particle capture, helping lower energy costs and extend equipment life.

Yes, Tier1 air filters are proudly manufactured in the USA. This 16x20x1 filter is constructed with 100% synthetic electrostatic pleated media supported by a galvanized metal mesh backing and a sturdy beverage board frame. Unlike fiberglass filters, the synthetic media resists moisture and won't break down over time, ensuring consistent MERV 13 performance throughout the filter's entire service life.
