Number of Germs on the Inner Layer of a Cloth Mask

Abstract

The effectiveness of cloth masks is determined, among other things, by the filtration ability of the type of material used and the number of layers. There is still little information about the effectiveness of using cloth masks in terms of the number of germs and the length of time they are used. The study aimed to determine the number of germs present in 3-kind cloth of masks made from different types of materials and different durations of use.
