O2 Nose Filters
O2 Nose Filters are a nasal dilator paired with advanced 3M filtration technology. The innovative electrostatically charged filters capture 90% of harmful airborne particles at PM10 and 65% at PM2.5.
The filtration efficiency of the O2 Nose Filters varies based on the size and speed of the particles. Testing has demonstrated 65% efficiency at PM2.5 and 90% at PM10.
