@Jessicam6946 Jessica, that is just not true. 2-ply or 3-ply masks perform quite well. Fit is actually most important. BTW - K95 masks are constructed of fabrics and synthetic non-woven polypropylene fabric. https://t.co/ABQKevvYnF
@KevinELemaster1 @DACDAC4DAC According to "the studies", a 1% gap renders them ineffective. https://t.co/H1UJbTRCRV
@Maw42478295 @fluffymason @SenSanders You are not wearing one 'correctly'. Proper fit testing is difficult and then even a 1% gap in an N95 mask causes it to be ineffective. Perhaps this is why even in countries where these types have been mandated, the s

@pauloesco @shanewaring @denise_dewald @GenBlair But again, masks that are not N-95 are much better at protecting others than they are at protecting the wearer, and there’s nothing wrong with that! https://t.co/jUtQkRxnHk
