Very easy to use. Not heavy and easy to fill. Top just lifts off to fill, and reset it back on. Not noisy. Sits on a dresser and does not leak. Had one for years and just ordered another one. With the changing weather here, one bedroom door wouldn't latch correctly. Bought one for that room and the added moisture has the door working properly again.

Great product!

This product was easier to use than I anticipated. Easy to fill and clean. I love the adjustable control. I start it on high a few minutes before bedtime and then turn it to a lower setting at bedtime. We wake up breathing easier and less congestion. Highly recommend!

Best humidifier ever!

Second one I've purchased (baby tipped the first one and water went down in the fan and killed it. Lesson learned.) it works like an essential oil diffuser-- small vibrating plate causes "fog" which is blown by a fan out a chute at the top. Every surface can be cleaned; no hiding spots for mold, no nasty filter to replace. It does put out a lot of moisture so don't set it near or on anything that cannot get damp ( wood, leather, etc) in all, a fantastic little machine.
