Wide Compatibility:  The 20×25×1 air filter is a direct replacement for the original filters in furnaces, air conditioners, and heat pumps. It improves the operational efficiency of your entire HVAC system, purifies indoor air, and protects your family’s respiratory health. Actual dimensions:  19.50×24.50×0.75 inches

MERV 11 High-Efficiency Filtration:  SUIXINEYI uses MERV 11 synthetic filter media that meets the MPR 1000–1200 and FPR 7 filtration standards, capturing 95% of dust and effectively blocking pollutants such as pollen and pet dander to fully protect both residential and commercial spaces. The filter layer ensures smooth airflow and does not obstruct the unit’s air circulation.

High-Quality, Sturdy Construction:  Features an easy-to-install cardboard frame paired with a double-layer steel wire-reinforced backing panel. Compared to standard cardboard filters on the market that are prone to damage, this design offers significantly improved durability, resists bending and deformation, and withstands extreme conditions such as high and low temperatures.

Long-lasting, Consistent Filtration:  We recommend replacing the filter every 90 days to maintain optimal filtration performance; in environments with high dust levels or where the equipment operates frequently, replacement intervals may be shortened to 30–60 days.
