Review on 🌬️ Revolutionary Adjustable Breathing Filters: Reusable and Washable for Superior Air Filtration by Onsommoshit Mathews

I bought these to help prevent glasses from fogging up. Yes No. still sweating I've heard people say that masks with a breathing valve are not good for fighting the virus because they allow germs to enter, so I don't wear them often. The quality is good but if you're looking for something that will help with breathing and fogging up your glasses I'm afraid to look elsewhere.
