Our Filters

Our replaceable nano-fiber filter inserts that are made specifically to fit our masks consist of a membrane that is made of a proprietary blend  of polymeric nano-fiber.

The nano-fiber is made of world-leading material that consist of ultra-thin fibers, about 1000 times thinner than a human hair. These fibers form a spiderweb-like membrane that captures tiny particles.

Our nano-fiber filters are made in the USA.

Our nano-fiber filter features:

• 95% Filter Efficiency at PM0.3
• 100% Filter Efficiency at PM2.5
• Tested in an independent lab based in the USA
• Test conditions:
• Flow: 32.2 liters/min, Resistance: 31.9 mm H20, Penetration 4.76% •
• Mean particle size (MPS) 0.3 ± 0.3 μm
