Filtration technology: made of activated carbon and non-woven melt-blown filter cloth, five-layer filter system effectively keep away from PM 2.5 and a range of airborne contaminants.
1.The first layer: high efficient filter cloth filter the dust of micron.
2.The second layer: meltblown cloth to filter industrial pollutants, automobile exhaust, second-hand smoke pollen allergies.
3.The third layer: high efficient filter cloth filter benzene and a smaller function of filtering dust microns.
4.The fourth layer: activated carbon cloth filter density, smaller material.
5.The fifth layer: spunbond cloth, filter out all kinds of harmful substances.
Note: These filters do not block airborne coronavirus particles. They do, however, add an additional layer of protection to your standard cotton masks recommended by the CDC for the general public.6.The sixth layer: spunbond cloth
