Rating : - Great humidifier
We've had this humidifier for 3 years now and it still works. I've purchase 2 different brands before this one and I love how quiet it is. I believe I've had this so long because of the cleaning I give it after 24 hours of use. I clean it out with distilled water and white vinegar and that helps keep the mold from growing into a problem. A definate must have!
