This Tabletop Humidifier is perfect. I bought 2 of these for my home and keep one in the master bedroom and one in the living room.  They keep my home free from static.  I just use tap water (we have a well) and I don't see any white residue anywhere in my home. The air is fresh and smells clean. And the different colors that glow from the humidifier are beautiful to watch as they change and blend one into the other.   My pets and loved ones no longer get shocked which makes them happier with me, and so I greatly recommend this lovely Humidifier.
