O2 Nose Filters with 3M Filtration - Nose Filters for Allergies - Nasal Filter for Allergies - Nostril Dust Mask, Smoke & Allergy Filter (Trial Size, Pack of 4)

I bought these to help prevent snoring and a stuffy nose at night. I bought this specifically to try the sizes so I could order more if I liked them. For me, the small was a good fit. I don’t really have allergies, but I wake up with a clear nose every morning I wear these. No smell, which is nice. They keep my nostrils open so I feel like I’m breathing much better, too. Quality is fine to me, not super cheap but not super stiff and long-lasting either.

The actual filter in these is really thin and doesn't filter fragrance or odors. I ordered sizing pack and found right size for me, but even though it "fits", it is uncomfortable. IF the design of the filter was as thick as the round plastic portion holding it then maybe these would be worth using. I did not notice any allergy relief. Not worth the money.

Appreciate the thought and creation of this item. Was looking forward to trying it out when out doing yard work with all the dust & pollen in the air. Worked a little, but unfortunately none of the sizes in the pack worked well for my narrow/long nostril shape causing them to either fold completely inward or leave half my nostril open defeating the purpose. Great item if you have proper oval/round shaped nostril openings!

My husband said the sample case is good for him to find the suitable size.

These are great for going to the dentist or getting a driver's license photo etc. or anywhere you have to remove your mask. I wouldn't want to wear them all day but great for a short period. Definitely recommend getting the sample pack to see what size works best

I was really hopeful that these would work, they’re surprisingly comfortable and I feel I could wear them all day. But the filters in them are very thin and flimsy…. I went to put them into my nose just to try them out and maybe my finger went through the filter part or something, because I went to remove them only a few mins later and the little cotton (or whatever it is) was ripped. Though, I didn’t notice that my finger went thru so I’m not sure what happened. Maybe when I flexed them to put them up my nose it ripped it? I’m not sure. But I feel like if my finger went thru it I would have noticed? SoI guess I’m not totally sure what happened. When I went to put them in my nose they were fine, took em out a few mins later and they were ripped. The only other alternative is maybe I breathe too hard and that’s what ripped them? Both are busted and seemingly in the same spot on both sides, so who knows. If they made them more durable and stronger filter part, I would totally try again because like I said, they were super comfy!

Work great

I bought the package with multiple sizes to see which one would fit. None of them stay in place. They just flip around in the nose, which means that they're not actually filtering any air, so their useless. Good idea, poor execution.
