>>The homemade cotton masks captured 50% of 0.02-1 micron particles, compared with 80% for the surgical mask. Although the surgical masks captured 30% more particles, the cotton masks did surprisingly well. The researchers concluded that homemade masks would be better than nothing. > >>Data shows that DIY masks made with a single layer of cotton clothing or a tea towel can remove around 50-60% of virus-sized particles. This means they perform worse than surgical masks and FFP2 (N95) masks. Wearing the homemade masks for 3 hours had no significant effect on the filtration efficiency. > >[https://smartairfilters.com/en/blog/diy-homemade-mask-protect-virus-coronavirus/] > >Sollte die Dinger nach einmaligem tragen natürlich abkochen.
