O2 Nose Filters with 3M Filtration - Nasal Screens for Allergies, Dust & Smoke - Drug-Free & Latex-Free Nose Filters - Invisible Allergy Protection (Large x 10)

I’ve tried so many allergy products over the years, but these nasal filters are one of the few that actually help. They’re small, comfortable, and surprisingly effective at blocking out pollen and dust. I could breathe freely without the usual itchy nose or watery eyes. The design is clever — once you insert them properly, you can barely feel them, and they’re not noticeable to others. The pack also comes with plenty of replacement filters, which makes it convenient and cost-effective. If you have seasonal allergies or live in a dusty area, this is definitely worth trying. It’s a simple solution that really works!

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.

I wish I discovered this sooner. Even if they are only a 1/3 as effective as a mask, they are infinitely more effective if you don't wear a mask at all. They are only a minor inconvenience compared to the mask. You need to get a trial pack and experiment with sizes. I got lucky with a nearly perfect fit. They could use the in-between sizes so total of 6 instead of 4, that's the only gripe at this point.

Great in theory, but poor execution. 1. There should be a size in between the large and medium. Theres a big difference in the two which is unfortunate. That would be the PERFECT size 2. The filter essentially had a hole 3. Hard to adjust both sides correctly without one folding over if adjustments are needed I finally got both sides to fit in correctly, but the filter was coming apart and sticking out of my nose. Not cool. If you wiggle your nose it may move and it’s hard to get both sides back in without one side folding over. Tried all of them so many times. The biggest could work, but it pushed my nose out and looked weird.

I have had a "runny nose" my whole life. I carry a handkerchief or tissues at all times, and frequently I am subject to sneezing 10 or 12 times in a row. When I work in my shop I wear an N 95 mask and I realized I don't sneeze, or have my nose run, in two places, when I am wearing the mask, or in the shower. So when I found these little filters that go in your nose I decided to try them. I read the reviews and learned it might be uncomfortable wearing them and everybody has a different size nose. After some research I ordered the sizing package from O2 because I could try the product and learn what size I needed. First size. If you order these you will find 4 sizes, for me it was the medium that worked best but the large actually fit more snugly but they were just too uncomfortable to wear for long periods. I found that after adjusting to feeling like your nose is dry and you want to get out whatever is in there, I could wear the medium size all day. But here is the bottom line. I have not sneezed for three days and my nose rarely runs anymore as long as I wear the filters. This was frankly a small miracle. I am looking forward to wearing them on airplane flights.

They are perfect for this challenging time and wearing them doesn’t freak out others on the street or in the shop ;) easy to breath

Great 👍stuff

Not sure if this works, people unfortunately see it and ask about it and it doesnt stay all day so you would touch it with your hand and that is not good

I am now satisfied with these but you should basically ignore the fitting guide. These are meant (apparently) to be fully inserted in the nostrils with the plastic half-ring tight against your septum. For me - as soon as i tried fitting them this way it wasn't long before at least one of the filters would turn side-ways in one of my nostrils resulting in ineffective filtration. There doesn't seem to be anything to grip them and keep them in place when fully inserted. However - what i noticed was is that there is a groove in the design of the filters. I found that by inserting them at the very edge of my nostrils i could get this groove to slot in-between and grip the cartilage at the entrance of the nostrils. I have demonstrated this with some pictures that i have added. Once slotted in place at the entrance of the nostrils they stay put (at least for me) but ONLY if you purchase a size one size larger than actually fits you. I initally bought the medium size - which was about the right size for me and although these slotted in ok and were comfortable there was still enough 'play' in them to eventually work themselves loose, (but not always). I then bought the large size - at first i found them uncomfortable as they really did stretch my nostrils but i soon got used to this. I also found them MUCH easier to breath through than the medium set as my nostrils were being forced wider. The extra size kept them firmly in place and they have not come loose since. The only difficulty is in the initial fitting as the larger size takes some practice to slot into place. Although they are more noticeable when inserted at the entrance of the nostrils they are still far less noticeable than walking around with a face mask on all the time. Once used i then remove them and clean them with an alcohol wipe and store them in the provided carrying case. I keep using the same set until they begin to darken and then i switch to a new set. I have also noticed that if i breath in through my nose and out through my mouth i get less 'runniness' in my nose. It is a real pain having to remove them to blow your nose. All in all i am now happy with them and i will continue to use them - i hope this review has been helpful.

Really difficult to fit in the nostrils in the way that prevents it from falling off.
