Good or bad studies???
Who is actually funding the studies?

It is your lungs. It you don’t take care of your self, who will?

I personally don’t like the idea, There are occasions where I have been working and fail to wear a mask and has to blow my nose. Not a pretty sight. I think a mask and dc does make a difference. I try to remember to wear one & run the dc and not to get lazy about it.
