The disposable PURE-MSK mask provides greater than 95% filtration efficiency for airborne particles and contaminants down to 0.3μm, including aerosolized particles, bacteria, allergens, mold, pollutants, fine dust, cigarette smoke and fumes.

At 4.38g, PURE-MSK is lighter than a sheet of paper so you won’t even notice you are wearing it. The unparalleled air permeability of the nanofiber material also makes breathing easier.

PURE-MSK combines thoughtful design while maintaining superior comfort and filtering efficiency even after 24 hours of use. PURE-MSK masks are the ideal solution no matter where you go or what you’re doing, especially when social distancing is simply not possible: traveling on the subway, bus, train or plane, watching a sporting event or concert, visiting a museum, or otherwise in a crowded space.

Frequently Asked Questions

Q: Is PURE-MSK an N95 Mask?

A: PURE-MSK was tested to verify conformity to NIOSH standards. PURE-MSK met all test method acceptance criteria for prequalification. PURE-MSK particle penetration and air flow properties exceeded NIOSH performance requirements for N95 certification.

Q: Does this mask filter Coronavirus (COVID-19)?

A: Pure-MSK is tested to filter >95% of airborne particulate matter.

Airborne viruses usually travel on aerosolized droplets of water, which are very large, between 5-15 microns. PURE-MSK filters >95% of particulate matter down to 0.3μm and completely filters particulate matter down to 2.5μm.

All products offered by Nano Air are made using innovative nanofiber technology which delivers superior filtration efficiency, permeability and breathability.

How To Wear a Mask
  • Remove the mask from its packaging and place over the bridge of the nose and beneath the chin.
  • Hook each strap around the back of the ears for a secure and comfortable fit.
  • Press and form the nose piece firmly with both hands so that mask molds to the contours of the upper part of the face.
  • With both hands again, cover the entire mask and adjust to fit the lower half of the face to ensure minimal air leakage.
  • Do not use if the inside of the mask is contaminated.
  • Do not crush or deform the mask for risk of compromising the integrity of the protective membranes.
  • For safe disposal, do not touch the surface of the mask after wearing and dispose of promptly.
  • If you are a pregnant woman, a child, a senior citizen, a patient suffering from respiratory tract or cardiovascular disease and feel uncomfortable breathing when you wear the mask, please discontinue using immediately and consult your doctor or other specialist if necessary.
