This vaporizer does a good job of humidifying the air as long as you follow the directions. Unfortunately, mine can "spit" water a good 1' on occasion. I dealt with this by placing the unit in a foil turkey cooking pan. It does use a lot of power because it's continuously boiling water. On the other hand, it can definitely help heat a room along with raising the humidity so you can lower the heat in the bedroom and it balances out.
