O2 Nose Filters with 3M Filtration - Allergy Nose Filter - Nasal Dilators for Sleep, Dust, Pollution & Travel - Anti Snoring Devices - Dust Mask (Trial Size, Pack of 4)

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.

I have a cricket farm and they smell. I got these in the hopes I wouldn’t have to wear a mask, but alas, they don’t work for me. Originally I bought the small because my nose is small and I can barely get a pinky tip into my nostril (think what you want or me, we all need to get inside our nose sometimes!) they were much too small, so I ordered a medium. These were also too small, because the shape of your inner nostril is not a perfect oval, or at least mine is not. A tight seal may be able to be achieved with a slightly larger size that may be fitted in there because skin and cartilage will make room for it. This said, if you do get them to fit snugly, they apparently pressed some sort of secret sensor inside my nose that sends a signal to clear whatever foreign object that’s in your nose out and my nose just started running like crazy and I had to keep pulling them out to blow my nose. You do NOT want to put these back in after you have to pull them out for excessive snottage. I wanted them to work so badly, but it is a no-go for me.

My husband said the sample case is good for him to find the suitable size.

We were hopeful this would help…my husband is a delivery driver on a dusty road. But they didn’t seem to do much. Maybe they help with minor things? Just not dust and dirt for us. We tried all the sizes too.

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

Work great

I was really hopeful that these would work, they’re surprisingly comfortable and I feel I could wear them all day. But the filters in them are very thin and flimsy…. I went to put them into my nose just to try them out and maybe my finger went through the filter part or something, because I went to remove them only a few mins later and the little cotton (or whatever it is) was ripped. Though, I didn’t notice that my finger went thru so I’m not sure what happened. Maybe when I flexed them to put them up my nose it ripped it? I’m not sure. But I feel like if my finger went thru it I would have noticed? SoI guess I’m not totally sure what happened. When I went to put them in my nose they were fine, took em out a few mins later and they were ripped. The only other alternative is maybe I breathe too hard and that’s what ripped them? Both are busted and seemingly in the same spot on both sides, so who knows. If they made them more durable and stronger filter part, I would totally try again because like I said, they were super comfy!

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.
