For example, I dislike rigid cup-shaped N95s, though Miller says many men prefer that style "for reasons I don't understand." Aaron measures various numbers for each mask: Filtration efficiency, on his own face. The initial cost for elastomerics aimed at the medical market typically ranges between $40 and $80. They cost much less per hour of use and an American College of Surgeons, revealed costs could be cut by about 90% by switching from N95s to elastomeric respirators. We also consider Project N95 a trusted supplier of the Powecom and N95 masks. Using this guideline, a rotation of just five respirators could last you 25 days, Miller notes.
