Question from Irene
Hello, with people making do it yourself masks, I have seen that Blue Shop Towels are being recommended as they are considered to block small particles more effectively than any cotton, even if doubled. My concern though is whether they might have a level of toxicity if you are breathing through them. Can you let me know? I am in the process of trying to make masks for my family and I don’t want to put them in danger.
Lisa’s Answer
I looked at several different shop towels. Some claim to be made of polyester, some polypropylene, and some recycled fibers. None had a MSDS. What I really would like to know is if they are treated with anything. If you would like to call a company that makes them and try to find out the materials used as well as any treatments I could give you a better answer.
