This could have just as easily been posted to the Training section so excuse me if this is the wrong place.
I am required to wear a mask to work, and wear one daily when near other people. It is homemade, two layers of cotton with a pocket for a filter, I have been using synthetic shop towels in the pocket as a disposable filter. By all accounts this is a fairly good non-medical mask for daily wear.
I just recently got back into the gym after a eight week COVID-19 break. I also bought one of the new Under Armour sports mask for training. It’s three layers of synthetic fabric. It’s supposed to work a little like goretex, where it’s let’s out moist air, but prevents water droplets from entering, and it has some fabric in the middle which is describes as anti-viral. The masks have been backordered, but mine is supposed to come this week.
My question, I can’t find any third party sources that have tested this mask design, just various marketing materials from the manufacturer. I even did some scientific literature searching (I’m a PhD scientist, just not in the medical field).
Is this $30 mask any better than my $6 mask I bought from a local seamstress?
