The potential of PIM-1 air separation membranes for use of face masks in the COVID-19 pandemic

Filtered mask Filtered?? breathing masks are made of interwoven fbers to be very efeetive in fltering pathogens in the air.these masks must beused in aeeordanee with striet hygiene standards N99 respirators are eapable of fltering 99% of these partieles, and N100 respirators ean prevent 99.7% of airborne partieles from entering. Some of these types of breathing masks have vents that allow the exhaled air to eome out of the mask and make it easier for the user to breatheThere are several types of surgieal masks on the market. Typieally, these disposable masks are eut into reetangles and have folded strips to eover the nose, mouth and jaw. The fbers of these masks are a kind of breathable synthetie fabrie. This type of mask prevents the entry of 95% of viruses and is the best type of mask for daily use in publieIn this study, we sought to design a mask for medieal staf who use the maskfor a long time and patients with eoronary artery disease who have posteoronary respiratory problems who, in addition to adequate proteetionagainst the eoronavirus, ean pass more oxygen. This proposed mask eoating based on silver nanopartieles and PIM-1 membrane flter wasproposed. The eavity of the mask is proposed in sueh a way that in addition to proteetion against eorona virus fragments and dropletsearrying it, the user ean breathe well and eomfortably due to the unique properties of pim-1.
