If the mask is worn daily a filter will last about 4 weeks. We recommend cleaning the filter every week (with warm water and soap) so it will last as long as 8 weeks. Once the filter is uniformly light brown, we recommend switching it with a new one.
The mask comes with an instruction manual on how to put it together but if you need further assistance feel free to contact us at firstname.lastname@example.org.
