### ⭐⭐⭐⭐⭐ Excellent room humidifier!
*by J***T on January 7, 2026*

The ROSEKM humidifier is very quiet, very effective, and very dependable. It's small and easy to use. I've been very happy with it.

### ⭐⭐⭐⭐ Good Product
*by O***R on January 6, 2026*

This unit is super quiet. You can't hear it even if you put it up to your ears. Produces adequate mist. There are different mist settings. Love having a timer. The water container holds enough water for three or more nights if you only use it while you are sleeping. I'm giving it four stars for one reason. It is not a deal killer, but it is a mild irritation for me. The water is poured in from the bottom of the tank. Don't know how many times I forget the top lid comes off. It always comes off when I turn the tank over to refill the water. Again, not a deal killer but I think I would prefer a top filling appliance. Works great. No problem recommending it.
