They are perfect for daily respiratory protection against smog and other pollutants, which also makes them ideal for intensive physical activity.
If you are using our mask regularly and live in a heavily contaminated area, it is recommended that you replace the filters once a week. With lower wear, the N99 filter will last up to two weeks.
