DURATION OF FILTERS
Duration time for filters depends on the pollution level and the frequency of usage.
Generally speaking, to protect yourself from pollution or any airborne contaminant, we recommend to replace your filter every 2-3 days (if you are using it for several hours a day) or 18-24 hours of total use.
If you use it in a particularly dusty environment (eg. doing woodworking, gardening, etc) would be better to replace your mask with a new filter after you finish that activity.
