Easy to assemble, fill, and clean, and works great! The mist is very fine and has not soaked the carpet or anything else. Would definitely recommend!

Great, Simple Humidifier

We love this humdifier. Attractive design and the size works well in our bedroom. Was recommended on Wirecutter but I bought the simple version without wifi and it still does a great job. Super fine mist and I love that you can direct the vent at the top. Seems like it will be easy enough to keep clean. Would absolutely recommend.

Perfect for Small Bedroom

Wanted a humidifer for a small room that we turned into a bedroom for grandchildren when they stay over a couple nights a month. My number one priority though was it had to be easy to clean!!!!!!! in order to keep them safe from bacteria, and me from having to deal with a complicated cleaning ritual. This Dreo was budget priced, but has just the features I need. My grandson liked the soft blue "nightlight" too.

Just Right!

This humidifier works as expected. It has a number of options for expelling the water droplets into the air, and there is no need for a filter. It is quiet. I use it at night in the bedroom and have seen an increase in the humidity in what is an otherwise dry environment. I bought a small tray on which to place the humidifier just in case it were to leak, but there are no problems. It is easy to care for. I am more than satisfied. Thank you,Dreo!
