Users' feedback

Users quotes on Amazon.comMy wife has awful allergies and we use a humidifier in our room at night to help her symptoms. We decided to give this humidifier a try after seeing it posted on Amazon. The water bucket is easy to fill and the mist comes out cool and smooth to help cover the room with moisture. The humidifier runs all night without concern of running out water and is very quiet. We are thrilled this purchase turned out great and I look forward to a happy wife instead of cranky allergy wife."

Users quotes on Amazon.comI chose this machine to replace all my "cheaply-made" oil diffusers that are not able to handle everyday use. This machine is very well engineered and very quiet. The water tank is huge, and it diffuses our favorite oils nicely. The price was a very good deal and this machine is a "Big" step-up from the little diffusers that, just give out! We live in a very high and dry Rocky Mountain climate, and this machine adds the needed moisture to the air. Winter is coming and we will diffuse some Thieves oil to try to keep the flu and colds away. It also comes with a (2) year warranty if you go to the website. I recommend this product and Levoit as a company! "
