How many layers are your FLTR95 Sealing Face Masks?
print icon

FLTR95 Sealing Face Masks, both white and black, are made with 5 layers of protection.  Together, they provide excellent filtration that is comparable and often exceeds most KN95 masks.

The 5 layers are as follows:

1, Non-woven Polypropylene fabric
2, Melt-blown Polypropylene fabric
3, Hot-air ES Cotton (Polypropylene & Polyethylene)
4, Melt-blown Polypropylene fabric 
5, Non-woven Polypropylene fabric

 

FLTR95 masks are tested to the Chinese industrial standard (GB 2626-2019: Respiratory Protection - Non-powered air purifying particle respirator), which is the same test standard as regular KN95 masks produced in China. FLTR95 masks, however, have also passed the US NIOSH approval standard for a particulate respirator, 42 CFR Part 84, and ASTM F2100 Level 1 testing: Standard Specification for Performance of Materials Used in Medical Face Masks, providing additional assurance as to the quality of FLTR masks.
