PM 2.5 mask filters (60 filters total)

THESE SHIP SAME DAY IF YOU ORDER BEFORE 4PM (6) ten packs * I work in the ER and I use these everyday due to the N95 shortage many of my coworkers have been using these as an alternative and we have not gotten sick.So we ordered 2000 Be sure to wash your hands before and after mask removal because particulates can be on the outer surface of the mask which is why you should wash it after each use.
