BREATHE PURE WITH 'MY' PARTICULATE FILTERS
Each Particulate Filter in 'MY' Mask Series 3 lasts for 42 hours. Once it reaches a threshold of 42 hours, we highly recommend you remove the filter from the inner mask slot and carefully dispose the used filter in the garbage can. The outer layer made of activated carbon and copper is highly sustainable and washable. It lasts for 6 months (180 days) with just 1 wash cycle per week.
