Nice product

Although this one is bigger than I anticipated, I still like it. Had I known how large it was, I would have chosen the 1 gallon size instead. That's the only negative thing about this. Other than that, it runs quietly, the mist is fine, and it seems like it will be easier to clean than many of the others out there.

Quite and Efficient

I purchased this humidifier because of static. It's very quite. Puts out a good amount of steam. My hair no longer clings to my face in the morning when I brush it. Being winter time, it also warms up the room a bit. It is very easy to clean and remove parts. I have extremely hard water, which it built up on the inside of pump area, vinegar dissolves it fast. Definitely a good deal.

Honeywell Filter free warm mist Humidifier

"I am very happy with my new Honeywell 1.5 gal. HWM440 Warm Mist Humidifier. It has been a fantastic addition to my home! I love that it's filter-free, which makes maintenance a breeze, and the warm mist is incredibly comfortable in my 500 sq. ft. room. The essential oil cup is a brilliant feature that adds a lovely ambiance. Overall, a top-tier product I highly recommend!"
