Would probably work well if they were bigger
I might order the larger size, if the other nose filters I bought from another company don't work. I agree with others in the fact that just round sizes can be tricky. I have more oval nostrils so air gets around them, but I'm not quite a narrow nostril person either. I have terrible allergies so anything that keeps me from running around with rolled up tissue up my nose is great. I bought the small and they are too small.. I can feel them sliding around, and my nose isn't even that big. I think the added scent is helping more than the filters because I KNOW they are loose. But... I'm not sneezing right now... and I'm not a tissue walrus so.  For now it's helping. If you buy them, unless your nose is tiny or you're a kid, I'd say buy medium or large.
