Cambridge Masks are non-disposable and can be used for up to 340 hours for the PRO mask and 90 hours for the BASIC mask.
The duration for which the mask will remain suitable depends on how polluted the environment is when you are using your mask (see table below).
The mask will need replacing after extended use to ensure proper filtration. Taking care of the mask by following the product care and washing instructions will help maintain the cleanliness of the mask, however, it will not extend the life of the filters as the pollution will be locked into them.
