PM2.5 Filters

PM2.5 filters filter out particles that are as small as 2.5 microns. Virus particles are even smaller than 2.5 microns. However by including a filter in your mask, whether it is a PM2.5 filter or another filter, you are adding extra layers of protection to your cloth face covering. Each of the PM2.5 filters are made of 5 layers of cloth, including two layers of meltblown 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.

• PM2.5 filters are not equivalent to N95 masks. N95 masks capture 95% of airborne particles larger than 0.3 microns. PM2.5 filters capture particles matter larger than 2.5 microns.

• PM2.5 filters can be used continuously for 16-24 hours, or for 1-2 weeks when used occasionally.

• Sold in packages of 2.
