Review: 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!
Review: 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.

### ⭐⭐ Review
*by B***S on 22 January 2024*

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 design Many 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 notch Cons: Expensive Not reusable so once you find your size the others in the pack are useless unless you give them to someone else Looks like you have something stuck up your nose / draws attention Breathing felt abnormal entire time while using, you feel a slight blockage through your nose because its slightly impeding your airway Overall 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.
