Air Mask: N95 Anti Pollution Mask | HEPA+ Carbon Filter ...
1. N95 masks – This basic air pollution mask filters 95% of air pollutants. It can filter out most pollutants, even PM2.5. The N95 air mask has a separate passage (or air valves) which lets out the air after exhaling. This not only prevents moisture and fogging under the nose-bridge and eyes but also makes it more comfortable to use.
