Query: DO NOT BUY!!!

I have owned at least 5 humidifiers and I believe this is the worst! The water in the bottom turns yellow and yucky stuff floats in it after one night of running...It's a pain in the rear to clean!!! and doesn't come clean very well at all! And to top it off, I've owned it for 3 months and it sounds like the motor is giving out already...when I put it on high it starts up good and then in a few seconds, it's barely running! And it doesn't feel like it's putting much cool mist out into the air either....Poor choice for a humidifier...don't waste your money!
