I am sure its not good for you. I have been doing this 35 years and been wearing them for almost as long. Depending on what I am doing depends on how long I wear the mask. Some days 8 hours, other days not at all. Its a trade off for my line of work. Never had a breathing problem. Yet. I think they are charcoal with a particle filter over it. They are garbage after 40 hours in open air and are not for virus. Honestly though, unless you are walking into a high contamination zone I don't see an issue.
I did not know that but its probably worse. Its almost impossible to keep a good seal on your face when working. If you have a beard, faggedaboutit.
Prevents some paint, fumes etc... Yes
Prevents virus particles... No
Excessive mask wearing harm?
What are the everyday blue throwaway masks made of?
