NBDIB 100PCS Adult Activated Carbon Filter Insert Replaceable Anti Haze Face Filter Paper

This little carbon filter really does the trick. I past by smokers, and this carbon filter keeps most of the smoke out from my mouth. I sometimes use two, when walking, for double protection, under my face mask. You get 100 of them for a great price. Will last for months.

Great product. I put them in my washable masks.

I have ordered these a couple times and they always arrive on time and do what they're supposed to do. They are a little hard to fit into one of my masks, but that is an error of the stitching on the mask, I believe, and not on these filters.

Adds an additional layer of protection, especially for cloth masks which are not recommended for use without a filter. Easily fits into any mask with a built-in pocket. Cheap enough to be disposed of after just one use. Or you can wash the mask with the filter inside to extend the life for an extra wear.

These mask I sorts add a 5 layer additional level of protection for my face masks. Te help protect me from others and others from me. It has to help to some degree. Easy to use. Makes masks better and more efficient.

Good size, good quality and durable. Easy to insert and dispose of. Husband is very comfortable all day while working at his job sites. Hope this vendor last....

convenient
