High-Efficiency Safety After-Filters


Meeting or Exceeding OSHA/EPA Standards

Filter 1's Safety After-Filters are designed to attach to the Cyclotron Separator and will remove even sub-micron sized particles, meeting OSHA requirements for circulating filtered air as well as EPA standards when venting to the outdoors. As custom specialists, Filter 1 also provides after-filters as needed to fit various dust collection systems.

Heavy-Duty, Broad-Spectrum Filter Media

The standard filter media is 16oz. seared, felted polyester designed to hold large dust particles to the outer edges of the material, thus forming a filter cake which heightens filtering efficiency. Dust is easily removed by gently shaking the bags.
