Quiet and effective
The MS Round Ultrasonic Humidifier is great! It's very easy to use. It holds a gallon of water, which lasts almost 2 days, if you run it continuously. The bonus about this item is that it is very quiet - can barely hear it when it's in use. I like that you can control how much misting comes out of the item. I love that is has an aroma tray to add any type of essential oil, to create a light & relaxing scent, if you so desire. The night light button also provides a lovely "glow" of light, which you can change the color of. Overall, I highly recommend this humidifier.
Pleasing Humidifier
I am so far very pleased with the Ultrasonic Cool Mist Humidifier. I am happy with many of the features. The instruction manual is very easy to read and understand. (Manuals/instructions are often not included in reviews, but easy read instructions are a huge plus for me. ) The instructions for operating and caring for this unit are quite simple; not at all tedious or complicated. It is very easy to fill with water, easy to turn on and off, easy to adjust the mist output, and has an easy to use nightlight feature. You can choose your color or allow it to constantly change. The mist is very fine. Is does not drench or make the surrounding area feel saturated. The auto shut-off allows peace of mind as well should I forget to turn the unit off before it becomes empty. And, it is quiet. I particularly like the feature that allows me to add essential oils. It has a separate compartment with an aroma tray that is very simple and easy to use should I wish to add aromas. I like the size and shape of this humidifier as well; I find it aesthetically pleasing. Wile some people may desire or require the wi-fi enabled, and those with timers, I do not. This unit is all I need, with nice extras. I'm finding new joy in keeping life basic nowadays.
Attractive Humidifier!
This is a humidifier that will fit with just about any decor. It's long white cylinder shape, fits well in a corner and out of the way. It holds 1 gallon of water and what's really nice is, it has a scent diffuser. There is a small compartment that allows you to put a few drops of essential oil on a cotton pad (comes with about 10 pads) and then when turned on, the scent disperses through the cool mist! Almost like a humidifier and a scent diffuser all in one! It has 7 color lights and an adjustable controls, along with low tank and auto shut off. Nice humidifier that will come in handy during the winter months!
