O2 Nose Filters with 3M Filtration - Allergy Nose Filter - Nasal Dilators for Sleep, Dust, Pollution & Travel - Anti Snoring Devices - Dust Mask (Size X-Small, Pack of 10)

UPDATE: Pollen season started more than a month ago in SW Ohio. I have been using one filter/day for about 2 months. My nose allergy symptoms have significantly decreased. I only use my allergy nasal spray at night, before bed; and, maybe once a week, I take an oral antihistamine for some whole-body allergic symptoms. Before the nose filters, I had to take oral antihistamine daily from March to the first frost, in addition to my allergy nasal spray. To check the efficiency of the filters, one day I decided not to use them. By midafternoon, my nose was bright red, itching, and running like crazy. So, the next day, before I put the filters on, I did a nasal rinse. I have not stopped using the filters daily since, and now things are much better, like before. I have been using both types of filters, the 3M and the Welder's version. Both work for me, with the 3M being more comfortable. I put them on as soon as I wake up, and I take them out right before going to bed, because I sleep with a CPAP. I do not know if people notice them, or if they are just being polite by not asking me about them. It does not matter to me. I will continue using them as needed. They are really a life-changing devices, for the better.My first time.I got the Trial Size, and like with the Welder's version, the XL is the winner.My review is a comparisson with the Welder version, which I tried for the first time yesterday, for more than 12 hours straight. I did the same with the 3M.The 3M version is softer, its "presence" in the nose is easier to ignore.Because of its softeness, the 3M version is a touch harder to accomodate inside the nose. I had to try several times, whereas with the Welder's version it was easier.Once properly set, it does its job of filtering what is supposed to filter. Same as the Welders' version.I am "sensitive" to one of my cats, and with either one of the filters I had no issues whatsoever.Both did not cause any irritation whatsoever inside my nose.One interesting observation: With the 3M version, I can see the filtration membrane moving back-and-forth as I inhale/exhale; whereas with the Welders' version I could not.So, my conclussion is: you cannot go wrong with either one. If you prefer the slight better comfort inside the nose, in spite of being a little harder to insert properly, go with the 3M.I am going to have both versions with me, for now.It is not Spring here in SW Ohio yet. That will be the next real test for me.Then, I plan to travel to the Caribbean (forever Spring) in the summer. Another real test for me.Then, at the end of summer, ragweed season. That is the nuclear test for me!!I will update me review then.

These are quite good. I have used other kinds, and these are comparative. I didn't notice when ordering that they are disposable. You can use them a few times. But for the very good price, I would say that disposable is fine. I ordered the "Find your size", which is very helpful.

They work very well just wish I could get a bigger pack

While the intention for this product is phenomenal, the result of using them is not. It is difficult to breath through these filters, and they would slant as you breathe in. I took these on a trip to Thailand, only to take them off less than halfway through the first day. My recommendation, use a mask instead. Much more comfortable and less complicated.

I'm allergic to cats, I've got 20. I don't like cats...lol. I'm outside "playing", yard work and projects. I live in FL. It's so hot and to have to use a respirator outside, with the humidity... Inside, the 3 cats that I have in my home, my eyes will get itchy but I don't sneeze or have to wear a respirator inside my home. They're so comfortable and easy to use. Where have these been my whole life? I started with the sample pack. I ended up getting the entire package of size medium. Getting the trial/sample package...I'm a 5' female that weighs about 90 lbs. I highly recommend these.

Comfortable, easy to breathe through--yet seem to help filter out stuff going in my nose. Great for airplanes or other crowed areas where you don't want to breath someone else's human exhaust.

I purchased these as an alternative to a full mask when traveling frequently for work. This was post-pandemic in 2023.Context - I am immunocompromised and travel for work to NY, Atlanta and LA regularly. I don't like to wear a full face mask as we all know now they can be a pain for various reasons but did want to try this as more discreet extra protection against germs/allergens when flying and navigating densely populated areas.Pros:Easy to place designMany sizes included - very important to use the right size (I have what I consider a "normal" size nose and wore a medium)3M filtration is top notchCons:ExpensiveNot reusable so once you find your size the others in the pack are useless unless you give them to someone elseLooks like you have something stuck up your nose / draws attentionBreathing felt abnormal entire time while using, you feel a slight blockage through your nose because its slightly impeding your airwayOverall I really love the concept and I am not too worried about the vanity of attracting attention by the look of it (My health>looks from strangers) BUT I don't feel this worked very well. I had to constantly mess with it to feel as though I could breathe normally thus I was having to put my hands in and up my nose area which defeats the purpose of protecting against germs.It is disposable too so the price is not justified for a 1x use product. Do not recommend.

I work in a factory that is very dusty, I hate wearing masks! These absolutely are better then a mask!!! Lifetime buyer!!
