Made from activated carbon and non-woven melt-blown filter cloth, the 5-layer filter system is designed to keep out PM 2.5 (fine particles) and a range of airborne contaminants.
Compatible with most face masks that have a pocket/space for filters and are easy to insert and replace.
When combined with a well-fitting mask, the filters can be used to protect the wearer from harmful dust particles, PM 2.5, vehicle exhaust, woodwork, pollen allergies and fumes.
First layer made of spunbod cloth and filters micron-level dust
Second layer filters industrial pollutants, automobile exhaust, second-hand smoke and pollen allergens
Third layer made of activated carbon cloth which also filters micron-level dust
Fourth layer offers filter density for smaller materials

Pack of 10
Individual filter dimensions: 12.1 x 8cm
Because the activated carbon in pm2.5 filters loses its potency over time, we recommend changing a filter after 2-3 weeks at the longest.
