How Effective Are Cloth Masks?

After this Covid-19 outbreak, there is a great increase in the use of cloth masks, but unfortunately cloth masks do not have proven protection against viruses or particles because they do not meet any standards. In other words, there is no measurement result about how much a 0.3 micron virus or a 4 micron cement dust filters. For this reason, since there are no test results, it is not possible to talk about the filtering feature of cloth masks.
