Absolutely! The Posh Pollution Mask is constructed of 4 layers (see diagram above):
The outside layer is fabric of silk, cotton, or polyester. As air is inhaled, the outside layer filters out larger dust particles and contaminants.
The second layer is a melt-blown, non-woven material that filters micro particles as small as PM2.5.
The third layer is military-grade activated carbon filter fabric, originally invented by the British Ministry of Defense for use in chemical warfare suits. This woven cloth layer is virucidal and bactericidal, meaning that as air is inhaled, the components of the fabric deactivate or destroy viruses and also kills bacteria. The carbon filter fabric has an extremely large surface area (1,000-2,000m2/g), being predominantly microporous. This, combined with the strong electrostatic forces developed within the cloth, enable the cloth to be highly efficient at absorbing vapors and solvents.
The innermost lining is made of soft-to-the touch poly-cotton that feels smooth against your skin.
The color coordinated exhale valve allows moisture and air to escape, leaving the inside of the mask dry and eliminating fog on eyewear.
Yes! The mask may be reused for weeks to months, depending on the level of air contaminants it is exposed to. If inhaling through the mask becomes more difficult, it may be clogged with small particles. If this happens, wash it as directed below and hang to dry. If washing does not improve performance, it is probably time to replace the mask with a new one.
That is an exhale valve to allow breath and moisture to be released from the mask, increasing comfort level. The valve has an inner silicone flap that prevents air from being inhaled through the valve, yet allows the breath to be exhaled. This also helps prevent glasses from fogging.
The Posh Pollution Mask comes in Large, Medium and Small sizes,. Large fits most adult males, Medium fits most adult females, Small fits most children or adults of very small build. It is adjustable to fit a number of different head sizes by adjusting the curly coil back closure on the mask.
