These disposable N95V NIOSH masks are equipped with a low-resistance exhalation valve that helps reduce hot air buildup and makes breathing easier in hot and humid environments. They effectively filter 95% of solid particles and liquid aerosols that do not contain oil. Lightweight and comfortable, they are equipped with an anti-particulate respirator. Metal- and latex-free, they are made with half-face sealing foam, and their shape is moulded for greater comfort. Please note that H-Series masks are not intended for medical use.
