O2 Nose Filters with 3M Filtration - Allergy Nose Filter - Nasal Dilators for Sleeping - Nose Filters for Dust - Anti Snoring Devices - Dust Mask (Size X-Small, Pack of 20)

I and a welder and blowing black snot is frustrating and unhealthy theses do not completely filter out all the metals but they do the most they can! You can visibly see the black it prevents from being inhaled. No black boogers and no sinus issues. Every welder should try & used these!

I have a cricket farm and they smell. I got these in the hopes I wouldn’t have to wear a mask, but alas, they don’t work for me. Originally I bought the small because my nose is small and I can barely get a pinky tip into my nostril (think what you want or me, we all need to get inside our nose sometimes!) they were much too small, so I ordered a medium. These were also too small, because the shape of your inner nostril is not a perfect oval, or at least mine is not. A tight seal may be able to be achieved with a slightly larger size that may be fitted in there because skin and cartilage will make room for it. This said, if you do get them to fit snugly, they apparently pressed some sort of secret sensor inside my nose that sends a signal to clear whatever foreign object that’s in your nose out and my nose just started running like crazy and I had to keep pulling them out to blow my nose. You do NOT want to put these back in after you have to pull them out for excessive snottage. I wanted them to work so badly, but it is a no-go for me.

Not comfortable enough that you can get a child to wear them. Guess I will have to buy a larger pair and show him how it’s done.

A little pricey but overall great for welding. Kept the soot out of my nose

I was to get these nasal filters because I thought I had found a product that would actually work. However I was really disappointed with this. First of all the design is incredibly uncomfortable they do not stay in your nostril. You have to have a really wide nostril for the filters to fit. Even when I shoved them in halfway up my nose they still would not fit so they were basically a complete waste of money because you cannot wear them I am shocked that they had good reviews and I would recommend something different. Either invest in a mask to wear over your face or invest in some sort of allergen blocking nasal gel I have bought a great allergen blocking nasal gel from Amazon they have many different types but for me it’s a great product because it does seem to cut down on the allergens entering my body and I noticed that when I wear it I do not get the symptoms that I normally would if I wouldn’t wear it for example when I don’t wear it my nose will run I will get a headache I will get congested and I’ll feel tired when I put it on in the morning. After bathing and having my nose Celine rinsed it is really really effective for me especially with my problems and sensitivities to mold

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.

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 designMany 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 notchCons:ExpensiveNot reusable so once you find your size the others in the pack are useless unless you give them to someone elseLooks like you have something stuck up your nose / draws attentionBreathing felt abnormal entire time while using, you feel a slight blockage through your nose because its slightly impeding your airwayOverall 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.

First off, these are not a replacement for proper PPE during welding, heavy metal grinding, painting, etc. But these are perfect for quick jobs that you otherwise wouldn't bother breaking out the respirator. They feel a little weird at first and take a little bit to get lined up in your nose, you look like your digging for gold trying to put them in...but once in place, you forget they're there!I ordered the medium and large, and honestly like the large better. They seem to be easier to line up. I measured my nose with calipers and the medium is the recommended size.Overall super please with these and will definitely keep ordering them!

Tutto ok

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

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