Experts have found that medical masks lose their effectiveness when they become wet. This vulnerability is reported by the Daily Star.
According to experts, water restricts the flow of air and thus reduces the effectiveness of masks. Experts recalled that this vulnerability can create more problems in the fall, when more precipitation falls.
As explained by the former representative of the world health organization (who) program to fight cancer Carol Sikora (Karol Sikora), moisture makes masks porous, so all types of masks are vulnerable in wet weather.
Professor of genetic epidemiology Tim Spector (Tim Spector) advised to change masks more often in the fall and make sure that they remain dry.
