Graphene mask, a new type of mask. In the key filter layer between the spunbond non-woven fabrics that constitute ordinary masks, the innovative application of a new type of graphene-polypropylene meltblown cloth material is formed.
The use time of graphene masks exceeds 48 hours, which is more than 12 times that of traditional masks. After 48 hours of continuous wearing, the filtration efficiency of the new graphene masks is only reduced by 4%.
