HUNTER QLS03-RD Ultrasonic Personal Air Humidifier (Red)

I purchased this item because of its high rating by Consumer Reports. It's simple design makes it easy to operate and maintain. The fact that it uses any regular 20 ounce bottle means there's no concern for bacteria growing inside. Bottle shows signs of pink stuff? Just throw it away and put on a new one. Opens easily so you can wipe the inside clean. Just yesterday I went to walmart.com to purchase another one but they only listed ones available from other merchants, which means I would have to pay shipping. As soon as walmart.com has them back in stock I'm buying another one.
