This thin light but durable paper is a mask saver to me. I use N94 daily and it it pricey to change mask every day. This thin layer inside help protect my mask from touching my skin and lips create stain and dirt. It does make my mask last longer or at least i can wear my mask more than one time without having pimples or break out issues!
Mask Saver (20EA)
It fits airqueen type of mask and is useful if you’re concerned about getting acne. Perfect for my oily skin.
I like that it is breathable and since it protects any type of mask from makeup, I can reuse the mask.
