Hello. This listing is for a lot of FIVE (5) Pairs of 2097 Particulate Charcoal Filters - EXPIRED.
If the hazard is mold, or if you are arc welding, then we would suggest the 3M 2097 P100 HEPA Filter that has a layer of charcoal. Active mold growth produces Volatile Organic Compounds (VOCs) that won't be absorbed by the 2091.
Purchased from a distributor overstock. Filters are expired and priced accordingly.
