N95 Mask with Valve: You can get an N95 mask with a Non-Return Valve (NRV) backed with unique filter media technology. The valve is designed in such a way that it helps you release your hot & humid exhaled breath quickly, preventing the building up of heat inside your face mask. The valve’s outer part is made from durable PVC plastic, and the inner part is of the soft silicon flap. When you inhale, the flap closes, restricting the flow of any outside particle entering your mask. On the other hand, when you exhale, the flap opens, letting the moist air go out, along with ensuring that no outside particle gets in. It helps your skin under the mask feel good and ensure that there is no humidity inside the mask that may cause your skin to itch. The mask ensures comfortable wearing and helps you stay cool and feels comfortable to wear for long duration continuously.
