O2 Nano Mask

With this cutting-edge technology, the O2 Nano Mask effectively stops 99% of PM2.5 particles, dust, and other air pollutants Pollen, dander, and other allergens Bacteria and other germs Harmful gases Smoke (including from wildfires) and other fumes

The O2 Nano Mask Filter is a 5-layer 
protective mask, which stops 99% of PM2.5 particles, including dust, and other air pollutants, pollen, dander and other allergens, bacteria and other germs, harmful gases, smoke (including from wildfires) and other fumes with its five-layer protection and hypoallergenic hydrophobic nanofilter.

Our filter has achieved 99% particle removal efficiency, based on EN143 European certification standards and third-party testing.

The O2 Nano Mask sports a refreshingly minimalist design with a focus on comfort. It’s made to fit in with your everyday life from your commute to your vacation and everywhere in between. The machine-washable O2 Nano Mask skin comes with three recyclable and replaceable filters that last up to 60 hours each, depending on air quality conditions.

Each O2 Nano Mask filter can last up to 60 hours of total use in a moderate AQI environment. As a general rule of thumb, the filter for the mask should be replaced once breathability starts to noticeably decrease. The filter will continue to function, though a fresh filter will provide more comfortable breathing. 

We’re currently in the process of obtaining N95 certification (July 2020). According to our extensive testing, the O2 Nano Mask is capable of removing over 99% of EN143-defined PM2.5 particles which is even beyond the required standard.
