I have a very sensitive nose as well, and have stopped using humidifiers completely since one caused mold issues in my home. What I do instead is use a nose clip (the kind swimmers wear).[1] It doesn't look great, but when I'm alone I don't care. The price is right (only $6), there's no maintenance, no noise, no energy costs, no risk of developing mold in you home from too high a humidity. It works great. Whenever my nose gets too dry I put it on and in maybe an hour or even less it's fine again. I also sometimes sleep with it on, when the air is dry enough to cause my nose pain.
