While these are small, when placed on my face before inserting it into my mask, it did fully cover both my husband and my own nose and mouth. It was a little difficult to breathe through as we pressed it against our faces, but when inserted into our masks, it was easier. I did cut one open to make sure that it did in fact have 5 layers and it does--none of which are made of a plastic material like other fake filters are made of. Since one of these could last for a week, I ordered a few more because we are both in education and will be expected (as of now) to report to our schools in the fall. Full disclosure, these do have a sticker on them that says, "Made in China", but frankly, so are many other products that we all use in our day to day lives.

Nice and thick, just slip in the sleeve of your mask and off you go. Lasts for one week each.

This filter provider more protection

They look like they do in the pic. The multi pack is a good way to go. This was a good value at the time I was looking. I saw a lot of reviews for other products about the filters having terrible, toxic odors. These did not have such reviews. I might’ve paid a bit more per filter but was ok with it given my lungs are already compromised.

These are very nice. However there's some slightly small side, which means you have to center them perfectly in order to breathe through them.

Love these filters that fit inside my cloth masks made with a pocket for the filter. I feel safer going out with these filters to protect me from Covid-19. I only use one in the middle of my mask. I will be ordering more.

It is thin. I thought it would be thicker and be big length and width. Not sure it is safe being smaller size. I will try using two side by side.

I reluctantly purchased these thinking they couldn’t possibly be that effective. I’m happy to say I was wrong. These make wearing a mask so unbelievably comfortable. Usually I rip off my mask when I get into my vehicle. With these, I often keep on my mask while driving. I don’t know how to maintain these, or the number of times they can be used before discarding. Will need to do some research on this. But I am happy with the product.
