The ProTeam 107315 Super Coach Pro Series HEPA Filter (2 pk) is a genuine OEM exhaust filter designed for use with ProTeam's commercial backpack vacuums. As part of ProTeam's Four Level Filtration system, this HEPA media filter captures 99.97% of particles as small as 0.3 microns, including dust, pollen, pet dander, and carbon dust, significantly improving indoor air quality during vacuuming. It serves as the fourth and final stage of filtration (exhaust stage), preventing fine particles from being expelled back into the air and protecting the vacuum’s motor from dust damage. The filter is easy to install and replace—no tools required—simply twist to unlock, remove, and snap the new one into place.
