The Sports Masks with PM2.5 filters are great for runners and cyclists. They can be used by healthcare officials, construction teams, during public transportation, traveling, hiking, or when visiting polluted areas.
The PM2.5 filters with their activated carbon layer have the ability to protect the wearer from tiny particles smaller than 2.5 micrometers (µm) in diameter. 2.5 µm is about 3% the diameter of a human hair. The 5 layer PM2.5 filter has been shown to successfully filter out bacteria and viruses. They are also the best filters to prevent air pollution from entering the body.
These 5 layer sports PM2.5 filters are great for both outdoor and indoor activities to filter contaminated air from harmful particles such as dust, pollen, wood- or metal work, gardening, sanding paint.
