NanoStop 5 Layer PM2.5 Mask Filter Insert - (1PK/10pcs)
What is PM2.5? This refers to "Particulate Matter that are 2.5 microns small" which also tells you the size of the particles stopped completely by the filter. Even though the coronavirus lipid envelope is technically smaller than this, research and lab tests show that PM2.5 filters in conjunction with a cloth mask will reduce breathing airborne particulates by at least 90%. PM2.5 filters, along with our NanoStop mask offers a high degree of protection with less inhalation resistance than a sealed N95/KN95 respirator.
Our disposable PM2.5 filters are made with FIVE layers of protection, including [Supermicro Satin (layer 1); Meltblown cloth (layer 2); Activated Carbon cloth (layer 3); another Meltblown cloth (layer 4); and Graphene Cotton cloth (layer 5)]. Each Filter is recommended for about 24 hours of continued use (about a week of occasional use).
