SUPERIOR '5' LAYER PROTECTION: It comes with '5' layers as shown in the image. PM2.5 name comes from these filters' original use as protection against Particulate Matter 2.5, the smallest and most dangerous form of air pollution. Airborne virions like the Coronavirus are even smaller than PM2.5 (the Coronavirus's lipid envelope is about 120 nanometers across). However, research has shown the material to capture nanoparticles of a similar size with a high degree of efficiency (approx. 95%), and lab tests show a PM2.5 filter with a properly-fitted cloth mask can reduce airborne particulates by as much as 90%.
PROTECTION WITH LESS STRAIN: The PM2.5 filter provides less strain on your heart. PM2.5 filters offer a high degree of protection, with significantly less inhalation resistance than a sealed n95/kn95 respirator. In laboratory testing, cotton masks + PM2.5 filters restricted inhalation by no more than 71 Pa, or less than 25% the max inhalation resistance of a NIOSH-certified N95 respirator (343 Pa).
PRACTICAL PROTECTION FOR WEEKS: Disposable PM2.5 filters are flat. and when used with our reusable face mask they take up less space than standard respirators. They never lose effectiveness, and you can use them continuously for 16-24 hours, around 1 - 2 weeks of occassional use (or whenever it becomes harder to draw a breath).
ATTENTION: Remember, no mask is 100% effective at protecting from viral transmission. The most effective thing you can do to stay healthy is wash your hands and practice appropriate social distancing.
