After two weeks of running our HVAC system with these installed, the difference in our indoor air quality is undeniable. The BNX TruFilter MERV 11 filters use electrostatically charged synthetic media that manages to trap microscopic irritants like pet dander, dust mites, and mold without choking our airflow. It is rare to find a filter that balances high-grade filtration with such low resistance, but these perform beautifully.
