O2 Nose Filters with 3M Filtration - Allergy Nose Filter - Nasal Dilators for Sleep, Dust, Pollution & Travel - Anti Snoring Devices - Dust Mask (Size Medium, Pack of 20)

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.

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.

One day, I was so deeply tormented by nats flying into my nose that I had a eureka moment and thought it would be super cool if there were “nose filters”. I searched this phrase in Amazon and these came up.I love them! My air quality is fine and I don’t have allergies. I only wear the filter at night to keep flying bugs like nats from flying into my nose. I wish they sold the X-Large in larger quantities.My only issue is that the filter’s fibers become loosened over time and end up tickling the inner part of my nose causing me to sneeze. This is when I change to a new filter but I wish that they were more durable bc they only last for a day.

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!

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