Particle Comparisons

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.

*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

This is the latest weapon in the war against city pollution — air filters so small they can be worn inside a commuter’s nostrils.

Providing a more discreet form of protection against dirty air than the large masks.

‘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!

Correct fit is essential for both long-term comfort and effectiveness. O2 Nose Filters are available in 5 sizes, Extra-Small, Small, Medium, Large, and Extra-Large, and the soft, medical-grade plastic conforms comfortably to all noses.
