Nose Filters with 3M Filtration | Nasal Dilators for Pet Dander, Allergy Relief, Dust, Travel, Pollution and Snoring | Clear Breathable Nose Plugs | Size Medium | Pack of 10 Nostril Vents

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

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…(

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.

Unfortunately, the sizing of these O2 Nose Filters seems not to be considered properly—they don’t fit everyone. The filtration itself is probably great, but they didn’t fit my nostrils and felt uncomfortable to wear. It’s disappointing because the product seems useful, but the “one size fits all” claim didn’t work for me

First off I'll start by saying I have always been on the smaller end of anything size wise facially. Glasses, Headphones, Hats, Beanies, Sunglasses, etc.. as an adult I fit kids and small adult item standards. I realize things such as nostril size can be different so based off of other female users who seemingly offered a similar situation I sized up from my normal guess of adult xsmall or small nostrils and went with medium. I even double checked them to my pinky tip making sure they weren't lurking there under my eye wildly flaring and far wider than I had ever realized, but nope they seemed pretty standard and maybe on the smaller side for nostril opening so I went with medium. WELL... Umm I am about to grab a cloth measuring tape at this point out of sheer curiosity because I actually burst out laughing when these things almost disappeared into my nose. I'm not sure how you'd go about measuring for a complete and accurate sizing but for the price point on some little nostril shoes I think the company should totally integrate an instructional tutorial of some sort. These, however, fit my very petite 9 year old daughter who still fits size 7-8 us size kids clothing. I'm not sure what to think at this point. The packaging is attractive. The product seems well made. It's all sealed and packaged nicely. I really would love to be able to give these a fair shot.
