Graphene mask, a new type of mask.In the key filtration layer between the spunbonded non-woven fabrics that make up the common mask, the innovative application of a new graphene-polypropylene melt spray cloth material is formed.

Graphene masks last for more than 48 hours, more than 12 times as long as traditional masks. After being worn continuously for 48 hours, the filtration efficiency of the new graphene masks is only reduced by 4%.
