A Game-Changer for Allergy Sufferers!
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!

Scam
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 after two months in the high pollen season in SW Ohio. I am glad I found these filters!
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.

Poor execution and sizes
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.

Worth it for allergies
I genuinely feel like they make a difference. I have really bad allergies, and there are only so many places that I can filter the air. My dog also sleeps in bed with me. I've started wearing these at night, and then if I am outside on days when the pollen count is high. Occasionally I'll wear them out other places as well as needed. The filter is relatively thin, yes, but they still can trap stuff. They aren't going to trap everything, but even if it traps 90% that is a massive difference for people with allergies (I'd guess its more than 90%). You are technically supposed to throw them away after 8 hours, but I will rinse them with hypochlorous acid and let them dry and reuse them a couple of times. So far it hasn't been an issue. This isn't the type of filter that will trap gasses, so you'll still be able to smell everything through it. If your issue is fragrances (like plug in air fresheners) it won't do you any good. I'm sure it would help some around smoke/fires, but you'll still have some particles get in. It also won't protect you from viruses the way an N95 would. It probably decreases the total count, but don't rely on it. If you are doing it for allergies, you'll want to make sure you start wearing them before you're allergies get bad. If you get congested and have a runny nose, that will just ruin the filter (or at least you'll need to be rinsing and drying regularly. Definitely buy the sample pack first to find your size. Yes its expensive for essentially one working pair, but it will be worth it. And overall I do find them pretty expensive for what you are getting. I can't see these things costing more than 5 cents a pair to make, but in my eyes spending $10 a month or so to be able to breath is worth it. If you have the right size, its comfortable and easy enough to use. But that is why you need to try the sample pack. I personally don't have issues with them falling out. Totally separate bonus though, if you have trouble breathing through your nose when you sleep, these will open your airways up enough (assuming you aren't congested). If you don't need them when you sleep (or only need them at certain times of the year), but you other wise snore, pop the filter out and just use it to open up your airway.

Nose filters
I am highly allergic to pollen! I will say this is the best $10 I’ve ever spent. Today was the first time I’ve been able to be outside for a long period of time without sneezing, or problems breathing. I ordered a medium and fits great!!

Didn’t work for my nose
Couldn’t get them to fit properly, they would cock sideways and made my nose itch. Cool concept but didn’t work for me. Maybe just how my nose is

Works well
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
