Level 3 vs N95 mask that doesn't fit : DentalRDH
May 08, 2014·And I have purchased some different types of masks that are comparable to N95. I am taking them to the mandatory fit test for one office next week. I ordered one from maskandshield. Com and am waiting on the bellurus 3d custom made mask that you can wear over the level 3 surgical mask to have a custom seal.
