> KN95s are easy to get and probably work a bit better than cloth masks (though probably worse than proper N95s).
ISTR recently seeing that 90% of "KN95" masks independently tested do not meet the published requirements for the rating, so, I'd hope that is worse than N95 (the requirements are slightly different, but substantively similar), though still probably better than cloth masks.
