Weddingstar PM 2.5 Disposable Mask Filters 5-Layer Carbon Technology - 50 Pack

The mask sizing chart on the product description chart was totally inaccurate so the kid's size I received is much too small for my 10-year old. Another thing I didn't like was that there was no data like the threads per inch and an ASTM rating. Without those factors, the buyer will not know the percentage of micron-sized particles that are blocked. All the nice words in the product description are worthless without some solid data.

When put in the mask horizontal as it's designed, the filter shape slips within the mask so that at any given time your mouth or nose are only covered by the fabric of the mask.When put in vertical (which is what we settled on until the 3D filters we ordered arrived), the mask is a bit misshapen but it affords coverage of mouth and nose. It stays a bit more secure in this direction but it leaves the sides of your mouth under the safety of the fabric of your mask alone.Total WASTE of money.

These filters have an unpleasant odor but diminished after soaking in alcohol and allowed to dry. Hard to breathe through. Air does not flow freely through them.

While I am not able to rate this product for the purpose intended, I can say it is very comfortable and seems to be made of good material. If it will prevent one case of the common cold or the flu, it will be worth the small effort to wear it. I bought it in the hope that it will provide some protection from CoVid-19 Delta variant as many people I am around refuse to wear their masks. I no longer feel that this purchase makes it more difficult for professional medical people to get their personal protection equipment as this product is available in many colors and patterns.

I had had trouble finding masks that fit my 8 year old grandson well. Weddingstar did the trick. They fit snuggly against his face, are comfortable and stay put. Most retail shops near me have stopped carrying masks since kids will be able to get vaccinated soon, but we never know where COVID will mutate next and I feel better having these inserts for extra protection as flu season hits the schools and science guarantees us there will be new strains coming.

My only problem is my glasses fogging. I can't quite get the nose clip to work well. It's so pretty (yes pretty) and well made. I only wish my glasses didn't fog.

These filters fit okay in the masks that we purchased that have slits in them. It slides out occasionally if the mask is not being worn. It also is difficult to talk when the filter is in place as it’s stiff and not very flexible. It seems to provide an extra layer of protection which I appreciate.

I put these in the masks that are in the same company brand, they're a bit to small (don't cover the whole face while in the mask, just more like the nose/mouth area). Paired with the same branded mask however, when I went on a plane twice for the holidays for 3 hours, I didn't get sick. So I guess it works? Or at least me being healthy/vaccinated and stuff with this mask was enough to keep me safer then most.

Should include with mask purchase as well. Its nice to be able to buy for replacement but when I purchase the mask orginally itd be nice to have 1 or 2 come with it.

I purchased these filters expecting them to be from the company Weddingstar..There not.Its got the 2.5 marking on them.But there a knock off.Chinese brand.Can't even tell u the name of them.Now with comparison to actual Weddingstar filter , they are the same size , different color of grey from Weddingstar filters.slight differences u can see once u put the filters side by side.Now do they work as well as Weddingstar filters lets hope so.Just becareful.Knock offs are out there.When u go on the page , it does say Weddingstar, but they are not.It doesn't say it anywhere on the packaging. Just Asian writing ..No Weddingstar logo's.Amazon thx u. 👍

I think for the price these are pretty goodPROS: They are individually packaged which are great. They do add extra layers to your mask. Obviously no mask can 100% guarantee you from catching any virus.CONS: They are a tad too small. As in as soon as I insert this to any mask and put that mask on. This filter will only cover part of your nostril and to your bottom lips. I don’t have a big head and the distance from my nose > mouth isn’t far apart. So it might not fit you so well.Just start with the minimum order. And if it works for you than order more. But should just order 10x first. Just in case it doesn’t fit you.

This is really thick. Like if you put it in cloth mask, you'd feel like things are sticking out. Honestly disappointed.The reason there are so many positive reviews I think is because I tried twice to leave a negative review and amazon rejected them. Don't buy it. There are alternatives on amazon that i bought last week that's much thinner and actually feels nice.

I Just purchased 2 pack and when I checked my purchase history, it showed as shipped from CHINA!DO NOT BUY!
