The masks themselves provide no more filtration than any fabric face covering. HOW ARE THE PROTECT FILTERS MADE? The ProTect Filters use 5 layers of filtering - one meltblown layer between 4 layers of non woven material - to provide high-level filtration. CAN THE MASKS BE USED WITHOUT FILTERS? Absolutely. The masks by themselves, though, provide no more protection than any simple fabric face covering. When your original ProTect Filter is used, there are three options: Keep using the mask, but without any filtering material (least protection) Use your own filtering material (degree of protection depends on material used) Use new ProTect Filters (high level of protection) The ProTect filters are designed to replicate the filtration levels of N95/KN95 masks, but are NOT certified by any government or independent health/regulatory body. As such, while they are a great option for day-to-day use in most settings (eg., shopping, office settings, etc), they should never be used as an alternative to medical-grade PPE (personal protective equipment) by medical personnel or by those providing care to at-risk individuals.
