My daughter's room gets really dry in the winter. I decided it was time for a new humidifier. I was tired of cleaning and hunting down replacement filters for my old one. I did a quick search of reviews online and came across this humidifier by Hunter. It is considered CareFree because it has a permanent filter you never have to replace.
CareFree does not mean you do not have to maintain and keep it clean during use. I recommend to dump the whole thing out and wipe it out 1-2 times a week. If you do not do this, the water inside will start to turn yellow and tiny pieces of particle will start floating in it. I believe this is the anti-bacterial material that coats the permanent filter.
The humidifier seems to work well, the water level does go down so you can see it must be going somewhere. It is a little noisy, but not any louder than any other humdifiers I've tried/used. It has a neat nightlight feature that they call NiteGlo. It casts a blue light through the water, which I found to be calming and my daughter found comforting. Of course, the light went out just this week and we have had it for about a year now. I have to look into how to replace it.
I would recommend this humidifier. It is easy enough to maintain, it is nice not to have to buy and change filters at all, I like the NiteGlo feature, and it is cool mist.
