Really good unit, with great features. When my unit developed an issue, the company provided outstanding customer service, thus the 5 star rating. They made things right, and their representatives followed up to make sure I was satisfied with their response. Plus, the unit comes with an 18 month warranty, so I felt assured that I would be protected against any problems for at least 2 winter seasons.
A number of folks have made mention of leaking in the unit. I was able to get this to happen by filling the tank to the very top. This causes the tank to overflow when the lid is placed on. But the water comes out from the bottom, leading you to think the tank is leaking. The solution is simple - don't fill it to the very top! Always leave a small air gap between the top of the tank and the water. Fixed!
This unit can pump out a LOT of moisture. But understand that if you have a forced air heat system, everytiime the heat comes on, it's blowing in tons of dry air, which defeats the purpose of the humidifier and makes it difficult for any humidifier to keep the moisture up. The fault is not in the humidifier, rather the volumes of hot air being blown into the room drying everything out. Something to keep in mind...
