Nano-fiber Filters (3 pack)
Orders ship within 1-4 days.
This product is for 3 filters.
The interchangeable nano-fiber filter inserts are compatible with our masks and consist of a layer of a nano-fiber material that fits in between the two layers of fabric, lining our mask.
The nano-fiber is made of world-leading material that consists of ultra-thin fibers 1000 times thinner than a human hair. These fibers form a spiderweb-like membrane that captures tiny particles.
Our filters have 100% filter efficiency at PM2.5 and 95% efficient at particle size PM0.3. They have been lab-tested in an independent lab in the USA.
