These are the filters for our re-usable mask range. The filters can be easily placed inside these masks with the hidden inside pocket.
Each filter should be replaced after 8-10 hours of use or when breathing becomes difficult. Our masks can also be used without the filters and they can be removed at any time.
The filters and masks received a 95% particle filtration from empirical studies. Please contact us if you would like to see the certificates of the product.
