Hubby & I can't breathe with all the other masks we've worn during this l-o-n-g pandemic, but he said "It's like not having a mask on!" He has COPD and emphysema and really struggles with surgery masks and N49! My question: Where may we obtain new filters & valve replacements?

I was having trouble breathing at the gym with a mask on. This makes it much easier and is very comfortable to wear.

During this pandemic I have bought many different types of masks and these masks are far more superior! Plus, you can’t beat the price.

Very easy to breathe with. Not sure how well it might protect one compared with a medical N95 mask. Well made and the valve can be opened or closed which is a nice feature. Good bang for the money.
