200Pcs PM2.5 Filters 5 Layers Activated Carbon Filters,Adult for Outdoor Activities Replaceable Anti Haze Filters Breathing Insert

It’s definitely not 5 layers like it says. I cut one open, only 2 layers. Top and bottom layer only. Don’t waste your money.

I got 19 PM2.5 Activated Carbon Filter instead of 20. Why?

The product is very, I mean, very comfortable, hope it gets me protected from the virus.

I am in healthcare and feel that a face covering that can hold a filter is better than a face covering alone. These were good quality and value for the $$$.

Works well. Small but aren’t they all?

These are what I was looking for! They it very nicely into my mask and have no odor associated with them.

I've got several cloth masks with pockets for filters, and this pack of 20 will do me nicely for a long time! So glad I found them.

These are great and fit nicely in appropriate masks. Provides an extra level of protection, which is important to me.
