These KN95 masks are designed for disposable use and should be replaced after approximately four hours of continuous wear. Fit and breathability are ensured thanks to the butterfly hanging straps that fit neatly behind your ears for effective protection. Each single KN95 mask is wrapped and sealed to prevent contamination and ensure you receive a safe and hygienic product. When putting on an KN95 mask, be sure to avoid touching and contaminating the outside- grip from the outside and always wash hands before putting on a mask.
Please note: KN95 masks are NOT Niosh approved N95 masks. The CDC has recently stated that KN95 masks may be suitable alternative when Niosh N95 masks are not available.
