The Nu-Calgon 4940-45 PermaFilter measures sixteen inches by twenty-five inches by five inches and is designed for HVAC systems. This filter uses static electricity to capture airborne particles effectively. Air is drawn through a series of specialized fibers, generating an electrostatic charge that attracts and holds dust, pollen, and other pollutants. The unique filtration process ensures improved airflow while maintaining high levels of cleanliness.
The PermaFilter is a long-lasting option that never needs replacing. With a simple wash, you can restore its filtration capability for continuous use.
