100 Pack Activated Carbon Filter Insert 5 Layers Fabrics Cotton Effective Non-Woven Filters (Adult Size)

To start, ALL 30 filters were in the package, and sealed in two groups of 15. I bought these to insert into our filter sleeve of our current cloth masks, and they cover our noses and mouth just fine. They aren't bulky, and I did the "candle blow" test, with great results. I highly recommend these, and I plan on getting more, if needed.Fun fact: I have a big head 😂, which is always a factor in buying things like this 😉

From artists, I've got several fashionable cloth masks with slit to insert filters. So I decided to purchase this filter insert. The items are professionally packed in original form, in a plastic bag and then in a box. Each filter are thick and do contain active carbon filter on top of additional layers. If you want to be fashionable (to make your statement) but at the same time would like to have a maximal protection, these filters are great choice. The shipment came right away. It is made in China, but shipped from US, I think.

This is the first time I will be using this filters. They arrived on time and most likely I would have rated it with 5 stars if all the filters were in the package, but that was not my luck. At this point I won't return them because I don't want to wait for a replacement and honestly I would get them from a different buyer.Again, make sure you get everything you paid for.

This is an easy to use filter and it last about 2 weeks before replacing. Depending how often you use them

I have not gotten COVID so I'm giving it 5 stars. The price is right and they fit nicely in the cotton mask with pocket that I purchased also on Amazon so thank you!

While this product is not N95 capabilities, coupled with two layers of quilting woven cotton, it’s better protection than not having any. Thank you for the quick shipping. They arrived as advertised.

This barely covers my nostrils and mouth which means if the mask moves at all, even a 1/2" it will be offset and I'll have no filter protection. They should have said this was for children.I plan on cutting some in half and gluing to the bottom of a full filter to get more height. Other than that, the material and thickness are great.

Great for my cloth mask with insert pocket!Excellent service! Shipped and arrived quickly!
