KN95 masks are classed as a filtering face-peice respirator (FFR). These can also be called disposable respirators.

FFRs are subject to regulatory standards around the world. These standards are recommended by health authorities during a pandemic or emergency as the standards full-fill physical properties and performance that satisfy clinical health and safety requirements.

4. Inner protection layer - high-quality non-woven fabric: soft, breathable and thin.
5. Final fabric protection layer - non-woven fabric layer, complete filtering.
