WE HAVE THE GOODS - FILTERS
These replaceable PM2.5 Face Mask Filters are designed to provide extra protection to face masks that have a pocket for filters.
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.
When they reach their full capacity, PM2.5 filters lose their effectiveness in trapping air pollutants so they need to be changed regularly.
The first layer is made of spun bond cloth and filters micron-level dust
The second layer filters industrial pollutants, automobile exhaust, second-hand smoke and pollen allergens
The third layer is made of activated carbon cloth which also filters micron-level dust
The fourth layer offers filter density for smaller materials
Fifth layer made of spun-bond cloth
