Protect Yourself from Airborne Particulates
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.
Common Particle “Dry” Sizes
Expected Filtration Efficiency vs Application
The eye can see particles down to about 40 microns in size, but there are many smaller and potentially harmful ones floating in the air around us.
O2 Filtration Efficiency
*About the Condensation Effect
Particulate sizes shown in the chart above are typically given as the ‘dry’ size. Pollen, mold, bacteria, and viruses constantly absorb moisture from the air around them, which can significantly increase their size by 80-1000%*. The technical term for this process is the Condensation Effect. Since moisture can increase the size of particles, it further enhances the effectiveness of the filtration technology in O2 Nose Filters.
For reference, the eye of a needle is 1230 microns.
In The News
‘Invisible’ air filter that you stick up your nose blocks 90% of pollution particles, allergens, and bacteria. It could help tackle the effects of pollution crisis that plagues modern cities.
Noses come in many sizes, and so do our filters!
