[QUOTE="RDKirk, post: 75140476, member: 326155"] That primarily applies to the masks with exhalation ports. Although physics do matter. Obviously if someone sneezes or coughs hard enough in a mask held on by elastic bands, the explosive force may be enough to stretch the elastic, deform the shape of the flesh, and force part of the exhalation outward...a partial failure. But that bit of exhalation is going to be vastly less in volume than it would have been without the mask, and it will have been considerably slowed so that it won't travel as far. Edit: Let me also add that we've got thousands of doctors, nurses, and staff working every day in covid-19 wards--absolutely 100% contact all day long with the covid-19 virus--wearing N-95 masks, and the percentage of illness among them is remarkably low considering they come into extensive contact with multiple active covid-19 infectious patients every day. Given that few lay people face 100% daily exposure (maybe 2% of the people we come into contact with on a busy day shopping will be infectious), an N-95 mask worn properly will provide satisfactory protection. It would take some heavy stacking of the odds against a person to get nailed. [/QUOTE]
