Medical Face Mask-PTFE Filter, New Filter with New Feeling.
Gemtier PTFE mask's filter is PFTE mebrance, it has much better breathablity, more durable protection and reduce fogging.
BFE of the meltblown mask will become lower when the wearing time increases (such as 1 to 2 hours), and its wearer will feel more unbreathable when the water vapor in the exhaled air gets the meltblown wet. For the hospital staff wearing the protective
goggles and the one wearing the nearsighted or farsighted glasses, the fogging happens a lot for the meltblown masks. Because of PTFE's excellent breathability, after securing the nose clip, most of exhaled heat are vented out directly through the PTFE face mask, which can reduce fogging on the wearer's goggles or glasses.
