Review on Efficient Home Humidifier: Powerful 2.1Gal/8L Large Room Whole House Top Fill Humidifier | Covers 500 sq.ft. | Quiet Operation | Runs up to 48 Hours | Auto Shut-Off | Easy to Clean by Chelsea Garcia

At first I was skeptical about this product considering there are so many similar humidifiers on Revain and the only difference between them is the name on the front of the unit. Accordingly, I was skeptical. The product exceeded my expectations when I first received it. However, the device stopped working after about 8 days. It produces practically no fog and switches off automatically after about 10-15 minutes. My guess is that the pump has failed and can't pump enough water from the reservoir to continue producing mist, and so it thinks the device has run out of water.
