We stocked up on some masks with vents so that the CO2 from breathing can be somewhat expelled to make it slightly more bearable to wear in a grocery store and now there is talk of them being outlawed! All along the CDC and others have concluded that masks are not all that effective no matter what kind one uses and at the start it was only recommended for those who HAD the virus in order to protect others. Then it changed to you had to wear a mask to protect others from you and you from others. Rarely do I see anyone who doesn't fiddle with their mask some of the time. They are uncomfortable, make you sweat, interferes with proper breathing and fogs up your glasses.
I just don't buy these polls that claim a majority thinks mask wearing should be made mandatory and come with some kind of penalty for those who refuse. I'll be glad when this madness is over and people can make up their own minds to wear a mask or not. I don't need nor want a nanny state!
I’m assuming that you know the masks with the exhalation valves are doubly useless.
The exhalation valve has no filter at all.
