FLTR masks (general use, FLTR95 sealing face masks, and NIOSH N95 respirators) are all designed and sold as single-use items.  It is not recommended to re-use these masks due to potential contamination after they have been worn. For any guidance with regards to masks used during the COVID-19 pandemic, we urge consumers to review information from the CDC.
