PM2.5 Filters

To be used with our face coverings, these filters are sold in a package of 2.

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 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.

• 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 hrs or for 1-2 weeks when used occasionally
