50pack PM 2.5 Activated Carbon Filter Insert Ship from USA …

Can confirm all 5 layers are are there! Ruined one from the pack just to make sure seeing as of right now there are many scalpers.It costs a bit more than the others, but having the peace of mind that all 5 layer filters were accounted for is more worth it to me

Before ordering I read most of the reviews for several different sellers and I noticed a common thread within a lot of them. That commonality being that many people had complaints of them either being scam sellers, being jipped on the total number of filters that they paid for, or the filters not having the correct number of layers that was listed in the description.That being said, when I opened my package, at first glance I thought that I too had been jipped because I ordered 20 filters but the package said 10pcs. However, upon further inspection I noticed that the zipper bag actually contained 2 packs of 10 and both packages do say 10pcs, but one of them was flipped around backwards, so on first glance it appears that it was just 10 in the entire zipper bag, although there are actually 20.Next, I decided to cut one open to make sure that they in fact had 5 layers like the description claimed. So I cut it open, and again on first glance it appears that there is only 3 layers. However, the front white layer and the back white layer are actually 2 layers on each side that are just stuck to each other. So after separating them (which took a bit of time because they initially didn't want to come apart), I can confirm that these filters are indeed 5 layers (2 white layers on each side and a charcoal layer in the middle).I am happy with this purchase and will definitely buy from this seller again when I need more.

Did the cut open test and found 5 layers and charcoal center. Just figured I confirm as I saw some reviews stating it didn’t.

Arrived in 2 days, pristine condition. These filters are exactly as described and pictured on the seller'spage. They will fit most cloth masks with pockets appropriately. Appears they are made with qualityand will do what they are made to do. I have purchased 15 more of these filters, since this review...

Holding these to my mouth I can not blow or pull air through them ... if air can't pass through it, how does it filter the air?

I have purchased PM 2.5 filters from other vendors and this particular one had some sort of plastic in betweem the white outer covers which made it impossible to breathe through. The filter is supposed to let air through, not prevent it from going through at all.

While the product description states Shipped from USA, don’t be mislead. These are made in China and do not come with a description of the materials used in the filter.

I bought this because they said they were made in USA! No its China so disappointed. They are not white filters the ones I got were gray!

Good quality
