O2 Nose Filters with 3M Filtration - Nose Filters for Allergies - Nasal Filter for Allergies - Nostril Dust Mask, Smoke & Allergy Filter (Size Small, Pack of 10)

I am glad I bought the different size. I was assuming my nostrils were a medium but turns out the large fit better. I have been sneezing so much, even after taking a lot of allergy meds. These things do help alot. My daughter’s boyfriend smokes weed at their house and it really makes my nose tingle and makes me sneeze. I wore these while over there and I couldn’t smell the weed. I took them out briefly to see if it actually smelled like weed and yep, it did! I stuck the filters back in. They take a bit of getting used to but it’s way better then sneezing

U used the other brand before, it was really effective for my allergy. But this one was hard to breathe, maybe too thick idk, I ended up using my mouth to take a deep breath occasionally still no relief after hours of use. Size was just right though…(

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.

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.

The small oval inserts don't seat or seal well in the nostrils, allowing air to easily pass by the filters. The surface area of the filter is incredibly tiny compared to traditional face masks. YMMV but I wouldn't trust these to prevent any toxic substance in the air from reaching your lungs. Not returnable. Made in China.

I bought these to help prevent snoring and a stuffy nose at night. I bought this specifically to try the sizes so I could order more if I liked them. For me, the small was a good fit. I don’t really have allergies, but I wake up with a clear nose every morning I wear these. No smell, which is nice. They keep my nostrils open so I feel like I’m breathing much better, too. Quality is fine to me, not super cheap but not super stiff and long-lasting either.

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!

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.
