Description
PM2.5 filters filter out particles that are as small as 2.5 microns. Virus particles are even smaller than 2.5 microns. Whether it is a PM2.5 filter or another filter, you are adding extra layers of protection to your cloth face covering. Each PM2.5 filter is made with 5 layers of cloth, including two layers of melt-blown cloth and one layer of activated carbon cloth to provide excellent filtration. Typically used to prevent the inhalation of air pollution particulates, PM2.5 can help increase effectiveness of non-medical face coverings.
Please note: PM2.5 filters are not equivalent to N95 masks or KN95 masks. N95 masks capture 95% of airborne particles larger than 0.3 microns. PM2.5 filters capture particles matter larger than 2.5 microns.
