Not working for me.
Not working at all. Actually worse than without in 2 different masks. Cloth and KN95.<br />That was money down the drain.<br /><br />I installed them in any way possible. Both ways don’t work. The mask seems less tight and feels like it lets more air through. Glasses fog up more now than without.<br /><br />I will change my rating or update if I find out I made a mistake.
