10 Pack Filter Replacement for Face Masks - Includes 4 Valves
Easy to breath thru carbon filter. Glasses don't fog up. Once you attach it to the mask, it is comfortable to wear all day, indoors or outdoors.
I like the masks cause they don't really let my glasses fog up while I am wearing them.
all items arrived on time and is accurate
I have been buying COVID-19 related products for over 6 months now and have not been disappointed once. If you contact customer support, a real person writes you and that is always a big plus. All products were terrific. I will be back for more unless we get rid of COVID-19 - Fingers crossed!
High quality filters for the mask I purchased
