xElevate Your Indoor Air with BNX TruFilter
The BNX TruFilter 20x25x4 is built for tight spaces and reliable performance in your HVAC setup. With an actual size of 19.5 x 24.5 x 3.625 inches, this slim filter fits standard 20x25x4 slots while delivering strong filtration. The media is electrostatically charged to help trap a broad range of particles without unduly increasing resistance to airflow, aligning with ASHRAE standards for initial efficiency and pressure drop.
Two key advantages stand out. First, a MERV 13 rating targets a wide spectrum of airborne contaminants, helping to capture many microscopic particles while maintaining steady airflow through your system. Second, the design emphasizes low air flow resistance, which can support efficient operation of your air conditioner or furnace and reduce strain on your HVAC system.
What to expect in daily use
- Better air handling in homes and small offices thanks to high-efficiency filtration
- Less dust and pollen circulating between room cycles, helping everyday comfort
