How long does the mask last for?

The Cambridge Masks are re-usable. The masks have a lifetime of 360 hours for the PRO and Non-valve masks, and 90 hours for the BASIC masks. This is approximately 3 - 6 months of use depending on the pollution rate or AQI in your area. Nonetheless, we recommend that you replace your mask after 6 months of use.
