Face mask filters PM2.5
PM2.5 Activated Carbon Mask Filter Replacement Pads for Face Masks
5 layers replacement filter to fit our face mask, 2 layers of non-woven fabric, 2 layers of meltblown cloth, and 1 layer of activated carbon, which can make your ordinary masks more protective!
Filters are compressed fibers and would not stand up to being washed. Filters last 5-7 days of casual use or 12-15 hours of consecutive use. It is a good idea to get more than one replacement filters.
PM2. 5 filters are shown to be effective in blocking the vast majority of airborne particulates, even the very smallest nanoparticles. The 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.
* Note: Please don't wash the filter because of the activated carbon
