We're on our second one of these. The first one we used for so long that the plastic in the back eventually gave out. And the second one has only very minor changes over the first one. I like the warm mist version, makes more sense for the time of year you typically need a humidifier (in most states). I like this this one has an internal humidistat so that you can pick the humidity that you want and set it and it will shut on and off when it's within a certain range of that humidity level (but you can't be too picky, it's a bit of a range.) I think this is the only one we've had that has worked pretty well with shutting on and off like it should. Oh, and I love that it doesn't use filters. Costs much less to use that way. Ease of Cleaning We typically need to take it apart once a year and remove the build up. This is so much better than other ones we've used that constantly need to have build up removed.
