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)

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.

If your confused on size to get, as a 6ft and 210 pound white male I would get the large size. It works wonders as a welder. Its appearance is very discrete. It took me some time to find the right nostril size for me. Its cheap and relatively inexpensive. As for comfort, it does dry out the ends of my nostril after some time and can be irritating. Its easy to use as it sits on the end of the nostril but not inside the nose.

DO NOT BUY THESE. TERRIBLE PRODUCT DESIGN THEN WONT REFUND FOR THE CRAPPY PRODUCT. GUESS CAUSE THEY KNOW IT SUCKS. Would turn or move flat against the wall of nostril. Would not stay correctly. Kind of pointless if I have to adjust it a million times.

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.

Good for riding dusty trails. Catch a lot of dirt and dust, fit well, easy to use. Comfortable, can still smell through them, function as they should.

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’m a welder and these helped out a lot!
