This is the second Pure Baby Humidifier I have purchased.  I had one for my forst child and still use it to this day.  We liked it so much we bought a second one for baby number two.  We have tried other humidifiers but found others were too difficult to clean.  These humidifiers are much easier to keep clean since the small parts can be removed and the opening on the tank is large enough to fit your hand and a sponge or brush for cleaning.  Our toddler loves the feature of the changing color of the lights.  Highly recommend
