This is the same high performance respirator as our SWTS01-N95, but with an exhalation valve to make it easier to breathe through in hot or humid work condition. Our unique exhalation valve offers maximum inhalation while providing minimal exhalation resistance. This feature and all those of our standard no.SWTS01-N95 combine to offer the proper fit and durability.
