I received a Pure Enrichment MistAire Ultrasonic Cool Mist Humidifier as a baby shower gift and after using it even just one night, it has made a huge difference. It's super easy to use and set up, it doesn't have a bunch of useless features, it runs all night and doesn't use up a whole tank of water, and it kept my sinuses and throat from getting sore at night. The mom who gave it to me swears by it for her baby and has several in her house now. The only feature I don't love is the bright power button, so I put a sticky note over it to keep it dark in my room.
