Works well so far. One annoying feature of this humidifier is that it has to be turned off for a couple of minutes every time it gets refilled, so that the heating element won't overheat.

Honeywell makes a great humidifier. My previous Honeywell lasted over twenty years, that is why I purchased this one! This new unit is even easier to fill. I love it!

I don't like filters. Bacteria grows and if you don't keep up on the maintenance of the filter, you breath in the spores! This is the best buy for people who can't maintain filtered humidifiers. Bay City MI K Jonesy C Hamell

Panned to give as gift then found out they had one so kept for myself. So finally thought I would open and use it tonight and after putting water in it, it leaked out of the bottome everywhere! oncw I looked inside, I realized resevoir was completely cracked with piece missing. Poured out remaining water and pieces were falling out. Not sure if happened in warehouse or during shipping but it is totally useless to me now. Never was dropped or injured in any way after receipt so I am quite disappointed. If it worked I may be able to provide a fair review but will certainly be asking for replacement or refund.
