It humidifies in in a tiny radius. I had it set to 55%. It runs like it should, but...it throws so much dust into the air, that it clogged my air purifier filters in 2 months (they last 6). Ultrasonic is NOT cleaner. And it doesn't work in a whole room. I had it in the living room. There is now dust in all of my kitchen cabinets/dishes. It throws white dust just fine. Humidify, it does not.

I love this humidifier! Since the first night I have slept 8 hours and awake once. I'm 70 years old and am used to getting up about 4 times a night. It's quiet and has options for how much light you'd like. I had a dry cough which is why I bought this, and it's gone. The only reason I didn't give it 5 stars is because it uses a lot more water than it says. Maximum 20 hours.

This is a very nice humidifier, very quiet but puts out enough moisture to keep the room where we want it. You can set your desired moisture level and it stays in the proper range. It is easy to clean and to add water to it. It looks good, and you can dim the lights at night.

Great humidifier large rooms or smaller houses. Large capacity water tank with convenience handle for remove and filling. Wireless remote allows for preference settings. Quiet operation. We run on the highest setting and we fill the water tank every 24-30 hours.

It works but it made my smoke alarm go off (why does that always happen at 2am??) so I moved it to another part of the house with a much larger room thinking that the concentration would be less but there it made all of my flames on my gas stove look like they were not burning correctly or fully as they went from blue to orange. I'm not sure I can use ut anywhere without issues

Using the automatic setting is great but it will definitely use more water than the regular setting.

Bought 3 of these.. First one great. Next 2 had to be returned as only way to reset after they ran out of water was to unplug.

Very quiet. Noticing a positive effect. Using reverse osmosis water and not finding any white dust as some others report.

Excellent humidifier for my kid's bedroom. The efficiency of the water tank and humidifier lasted 3 nights! Don't crank it to the highest level or it'll soak the surrounding area for about 4 feet out.

BEWARE! Great idea, but fails to work in less than 3 months. It has a 2 yr warrantee HOWEVER they do not honor it. I called customer service, and they were quite helpful while we were troubleshooting, but once it reached a point where it was obviously no longer working, they ghosted me. After sending them the requested pictues they have ended all communication. So - it looks good, but you are taking chances on this one! Read the other reviews - several have mentioned the same issue with it not working after just a few weeks or months.
