PM2.5 Activated Carbon Filter, 5 Layers Replaceable Anti Haze Filters, Protective Mouth Filter for Outdoor

I like that the product is easy to pack/carry and use along with any fashionable fabric mask of your choice, and it is a great value and alternative to the more expensive N-95 masks.

I love how good they are. Theu came in handy when California had fire. I will definitely be buying again to give to my family.

Perfect value for the money nice filters will buy again

Irem arrived quickly and undamaged. Just what I needed to add to my hangers.

Liked , insert for more protection
