Where I live, KN95 masks are readily available at stores where masks are being sold. KN95 is the Chinese standard of the U.S. N95 standard, the main difference being KN95 masks can be attached to one’s ears while true N95 masks must be attached with the two ribbons going behind one’s head.Where do non medical people get N95 masks? The only masks we wear here are cloth washables or disposables you can pick up at the grocery store. And, per public heath rules, we are to wear them entering church until seated when we may remove them. We must put them back on to go up and receive Communion, remove immediately before receiving, consume, and replace mask before returning to our pew.
Both N95 and KN95 block out 95% of the air.
