PF-i™ Filter Enhancement System for Outdoor and Return Air

The GPS Air PF-i is a self-cleaning filter enhancement system. The Opti-Lok™ technology improves an air filters ability to capture sub-micron particles, making it more efficient. The unit is designed for mounting inside ducts and air handling units upstream of system filtration.

The PF-i can enhance your current filters or be paired with GPS Air Opti-Lok filters to achieve optimal very fine particle reduction, with the removal performance of our proprietary MERV 11 filter being equivalent to a standard MERV 13 filter.

Protect your indoor air from pollutants and fine particles. Opti-Lok boosts your air filter’s performance, capturing even the finest sub-micron particles, for ultimate efficiency.
