PM 2.5 Mask filters can be inserted in the back side of your BB Lines mask. These are not washable filters and should be used with your discretion for cleanliness. Typically these should last a week of normal consumer wear (not professional healthcare). 


Sold by the single filter at this time. 


These filters are 4 layers with activated charcoal sourced from the US. 


NOTE: BB Lines does not accept returns on filters or masks due to sanitation risks. These masked are to be used at the consumer's discretion only.
