Humidifier is quiet, even on high speed. Tank is easy to fill and doesn't leak or drip when set back into base. Design allows for any possible "drips" when filling to fall into the water tray rather than outside of the humidifier. New materials for tank and base resist hard water deposits! Very easy to clean.

My experience so far.

I really like this model. It takes up less space. It is easy to use. I like that it is easy to refill with water. I'm waiting to see how it works when the outside temps go down. By that I mean will I have to refill the water holder more often. I need to know how often the filter needs replacement.

Run don't walk, you need this

I was getting very frustrated with how difficult it is to keep up with the complicated cleaning of the typical humidifiers and very concerned about getting sick because I couldn't keep up with the cleaning. Enter this product! I've only had it on for a half an hour and it already increased the humidity in my home by 10%. That's incredible. It is much quieter than you think, it's got a good size tank, I love the fact it has a UV light and the only regular maintenance on it will be flipping the filter at night and filling up the tank as needed. The tank and the base can go in my dishwasher for a weekly deep clean! I can't tell you how happy I am.
