GecterAdult PM2.5 Activated Carbon Filter 5 Layers Replaceable Anti Haze Filter Paper (100pack)

Does what is says, nothing wrong with it. It came on time with no damage

purchased this to go with reusablePurchased this filter to go with reusable fabric face mask with a slot to add filters. As its PM 2.5 it should suffice again particles of 2.5 microns but the filter itself is just too small to cover your mouth and nose. Depending on type of mask you put this filter in, it may be completely useless. Information and description of this product doesn’t explain recommended masks which makes it bit of a gamble (i.e. trial and error). It is not expensive therefore nothing to cry about but if you are looking for a filter to place in your favorite mask then I would recommend purchasing masks that gives you protection against viral/dust/pollutants instead especially considering these difficult times.

Not as expected

Very Good

Second time buying. I bought my first pack in July and I still have some but I don’t want to run out. They don’t cover my entire mask but it covers my mouth & nose just fine, it covers just enough of my nose which is my nostrils not my entire nose which is fine as long at it covers my mouth & nostrils. I definitely like having another barrier added to my mask, makes me feel more protected, my masks alone are too thin of a layer. They’re breathable.

These are exactly what they say they are. I sacrificed one and cut it open just to verify that it did in fact have the 5 layers it claimed to have, so I’m happy with that. Only reason I didn’t give this a 5 is that they aren’t very wide in length. They fit easily inside masks but it doesn’t really cover the width of your mouth if you were to heavily cough or sneeze. Having said that, I will continue using and probably buy again.

These filters are so comfortable. I think they basically can be used for any type of masks. I have the blue paper masks that I use with these filters. The filters protect your face, & also allow you to breathe freely. I really like these fillers. They keep the mask from breaking my face out. I make sure that I center the filter in the middle of my mask. Great purchase.

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.
