- The Replacement Filters are disposable supplies and cannot be washed.
- We recommend changing the filter once or twice a week, depending on the amount of outside exposure. If a mask is worn for casual activities at private or limited exposure areas for 8 hours a day, the filter should be changed once a week. However, if the mask is worn in areas with a large amount of open exposure for 8 hours a day, it should be replaced twice a week. The PM2.5 filter’s air resistance will increase over time as the spunbond fibers accumulate airborne particles, making it noticeably more difficult to inhale. When this happens, the filter should immediately be removed and replaced.
- 1 pack contains 10 carbon filters.
- Mask is not included in this listing. Please check out our linen mask collections.
