and Low-Pressure Drop Air Filters

Using our revolutionary nozzle design, the Ultra-Breathable and Low-Pressure Drop Air Filters are produced with both microfibers and nanofibers. This design system creates an open structure nonwoven with finer fibers that increases air permeability without decreasing filtration efficiency. The Ultra-Breathable and Low-Pressure Drop Air Filter provides superior breathing comfort and is washable up to 100 time.

Available Ultra-Breathable Polypropylene (PP) Air Filters:
  • ASTM F2100 Level 1, 2, 3
  • ASTM F3502 Level 1, 2
  • N95
  • N99

and Biodegradable Air Filters

The Compostable and Biodegradable Air Filter is made with biobased material which is both ASTM D866 certified as well as EN 16785-1 certified.

Our nozzle design processes bio-based polymers with significantly low Melt Flow Rate (MFR). This advanced nano technology has allowed us to commercialize our compostable air filters providing an affordable and eco-friendly option for our clients.

Available Compostable and Biodegradable Air Filters:
  • ASTM Level 1, 2, 3
  • N95
