Exhalation Valve helps reduce heat build-up inside the respirator. NIOSH approved for at least 95 percent filtration efficiency against certain non-oil based particles. Designed for particles produced by applications such as grinding, sanding, sweeping, sawing, bagging, or other dusty operations. This respirator can also help reduce inhalation exposures to certain airborne biological particles, but cannot eliminate the risk of contracting infection, illness, or disease.
