I love this Vicks Humidifer.  You put the water in and let it run. It can be a little loud but nothing more than a little back ground noise. We have used this for three years and it has helped each and everyone of our kids.  I like that you can put the vicks little strips that omits a nice vicks mentholatum smell.  It really helps with colds. It is easy to clean and keep clean. Every once in awhile your suppose to clean it out with some vinegar but worth it to not clean filters and replace them. I tell everyone about it.
