re: #162 Wendell Zurkowitz ((slave to the waffle light))
I was lucky to be given a pair of FFP2 especially as Germany now requires medical-grade facemasks (no home-made or improvised ones) to be worn in all indoor public places and even some outdoor spaces (crowded downtown areas, parking lots, etc.)
According to 3M, the KF-94 is equivalent to the FFP2.
