Over 95% Filtration Efficiency

PURE-MSK filters greater than 95% of particulate matter down to 0.3µm in size, including: 

  • Aerosolized particles 
  • Bacteria, allergens, and mold
  • Pollutants and fine dust
  • Cigarette smoke and fumes 

PURE-MSK’s nanofiber physically blocks these particles with impossibly small nanofiber pores measuring 0.2μm in size. As illustrated below, pollen is 100x larger than the pores, ultrafine dust is more than 10x larger and cigarette smoke is more than 3x larger so the filter effectively blocks these particles.  


Nanofiber Magnification


Air Permeability

PURE-MSK nanofiber has very high air permeability due to consistent pore size which results in a very high ratio of pores to surface area. The average PURE-MSK pore size is 50x larger than an air particle allowing for ease of air flow and better breathability.

Light & Comfortable

PURE-MSK is so light it can be worn comfortably all day long! At 4.38g, lighter than a sheet of paper so you won’t even notice you are wearing it.
