Duke University in the United States has conducted research on 14 different protective masks.
Analyzing the protective properties of the masks, scientists said that the protection of the mask type N95, used by health workers, is ideal for the pandemic, reports Qadin.Net with reference to publika.az.
In addition, layered surgical and homemade cotton masks have also shown good performance in preventing droplets from the mouth and nose.
Experts say that bandanas, necklaces and masks do not have protective properties. Although it looks good, according to scientists, bandanas and masks are not suitable for use. It has even been claimed that people who wear necklaces can spread the virus more than those who do not wear a mask: "Necklaces reduce the size of large droplets from the respiratory tract and make them more comfortable to follow."
