These popular SAF-T-FIT® PLUS N1139 Particulate Disposable Respirator - N99 are made of an improved latex-free and humidity resistant material that can be easily molded to fit facial contours. The increased inner volume of the new design makes the respirator feel less oppressive, and makes speech easier while wearing it. The resulting increase in surface area improves performance and reduces breathing resistance.
The full sealing flange assures a superior facial seal for an exceptional level of protection. Exhalation valve minimizes exhalation resistance, and evacuates moist exhaled air faster for greater comfort. Valve design provides maximum frontal protection of the valve membrane.
Respirators have a NIOSH-approved N99 rating (99% filtering efficiency for oil-free solid and liquid particulates).
Humidity resistant material promotes longer service life
