This unit works great. A few thoughts though. This will not leave a pool of water around the humidifier. You cannot see anything coming out of it. It works by evaporating the water off of the filter into the air using a fan. Other types use other methods and they tend to leave everything around the unit damp or even wet. This one does not. But because of that, there is a louder fan noise than mist-type units. We like the built-in humudistat feature and when the motor got really loud on the last one we had, they replaced the entire unit for free. We have two of these and we like them both very much.
