It filters pretty well.... if it fits your nose.

I have a wide nose bridge (Italian style?) and I find myself having to position it very carefully to be sure there aren't large open-air gaps up there (went so far as to use a dental mirror to test it out).

Supposedly there's only one size, but the japanese sites show 3... if only I read kanji.

If you have a small nose buying these is a good idea, but if you're wondering "will this fit?" I'd suggest going with 'breathpure' nose filers. though not currently sold on amazon. They're cheaper, uglier, and come in a variety of sizes for your under or over sized schnoz.

I decided to try this product because it is often annoying wearing a full dust mask. Especially during the summer months when it is so hot that the mask starts getting wet. This product works OK so long as there is not too much dust and you remember to breath through your nose and not your mouth. However, I wanted to use this product while woodworking. There turned out to be too much dust and it clogged the filter too quickly. So it is back to the full mask.

To those complaining that a round filter won't fit securely in a teardrop-shaped nostril: nostril shape varies by race. I'm thinking that maybe asian nostrils are rounder inside than caucasian nostrils. The lady in the photo seems to have fairly round nostrils, anyway. This product was designed by a Japanese company, and I'd guess it sells largely in asian markets. So, yeah, I wouldn't be too surprised if caucasians have trouble making it fit. And if there's even the tiniest gap for air to leak through, all the air will squeeze through that gap, bypassing the filter. I've seen pictures on the web of a flexible filter from Bio International Japan (the same company?) that might work better.

This is a great concept. The filter is barely visible when in place, which makes it possible to wear in public without attracting strange glances (unless you are already attract them--this won't fix that). But, for me at least, they don't seem to be shaped right. I'm not a nasalogist or anything, but it seems that the nasal passage is teardrop shaped (take a look sometime). So, it's really difficult for a round filter to seal everything off--I haven't been able to pull it off successfully and I don't have a very big nose.

That being said, even with only 80% coverage, I did notice some improvement. So, I do recommend at least trying them--especially if you have perfectly symmetrical nasal passages.
