TruAir Ultra provides NIOSH-approved P100 class protection, filtering at least 99.97% of aerosols below PEL. The TruAir Ultra mask is loaded with comfort and fit features to help ensure compliance, with a facial seal that conforms comfortably and securely to facial contours and adjustable, latex-free head straps that hold the mask snugly in place. A standard vent helps reduce hot air buildup, making breathing easier and reducing worker fatigue. Gateway Safety, Inc.,, (800) 822-5347. Booth 835. Circle 323
