FILTRATION TECHNOLOGY:  Made of activated carbon and non-woven melt-blown filter cloth, this product has a five-layer filter system to effectively keep away from PM 2.5 and a range of particles in the air.

10 IN A PACK:  The filters are hygienically sealed in pairs in clear cellophane wrappers.  We recommend changing your filter weekly. 

PM 2.5 FILTERS:  Get more use out of your fabric masks, by replacing the filters periodically. They can be used with home-made fabric masks or with pre-made purchased masks that have a slit inside.  Compatible with majority of dust masks available in the market.
