DCapTO: Great news proving N95 masks not only work to prevent inhaling Covid & other viruses, but also trap viruses inside the mask & touching them doesn’t leave active virus on hands. BUT just bc that was same for surgical masks, DOESNT MEAN THEYRE SAFE! Infected air goes straight into nose/mouth from gaps

New study by Linsey Marr: “We aerosolized SARS-CoV-2 & pulled it through masks. After 1hr we were able to recover infectious virus from fabric masks but not an N95 or surgical mask. When we pressed artificial skin against the masks we found viral RNA but no infectious virus on the skin.” #MasksWork

Stability of Aerosolized SARS-CoV-2 on Masks and Transfer to Skinpubs.acs.org The potential for masks to act as fomites in the transmission of SARS-CoV-2 has been suggested but not demonstrated experimentally or observationally. In this study, we aerosolized a suspension of SAR...

Well-fitted N95s work! Not all N95s fit every face so you need to try a few. Here’s a simple video that explains the science behind N95 respirators. The mask fibers actually attract tiny particulates, even the super tiny 0.1 microns of Covid virus, and traps them so they don’t get in you. #Covid
