Mold, dust, pollen, even airborne pathogens...don't take a chance with those single strap, paper thin "dust masks". For true protection, use our N95 Dust Mask (Moldex) two-strap respirator with exhale valve. The exhale valve keeps the inside of the mask cool and it eliminates fogging of your eyewear. Outside mesh netting holds the shape of the mask so it won't collapse. Seals easily and comfortably without a metal noseband. Contoured design with Softspun® lining assures all-day comfort. Certified under NIOSH 42 CFR84 to have a filter efficiency level of 95% or greater against particulate aerosols free of oil. Approval No. TC-84A-0328. Box of 10 masks, specifically fitted to women or men with smaller faces.
