Review: Excellent humidifier! - Sturdy humidifier. Easy to set up as well as easy to refill without spilling. It has an adjustable top to choose what direction you prefer the mist to go. I have mine in a fairly large bedroom and the humidifier handles it very well. It is also very quiet instead of making a noise like Niagara Falls like some units do. This is well worth the money.
Review: Compact, Quiet, and Reliable - It's. compact, very quiet, aesthetically appealing, and pumps out water vapor like there's no tomorrow. Am very happy I purchased this with the larger reservoir because it runs for hours before needing to be refilled. And with the cold winter air containing zero moisture, I run this humidifier in my bedroom 24/7 refilling as necessary. It's very easy to set up and put to use, plus the soft blue light is a nice feature in that it can be turned off or on. I would buy this one again.

## Questions & Answers

**Q: How noisy is the humidifier when it is working? I am a light sleeper and need to be in a very quiet environment to fall asleep.**
A: No worries at all. I am also a light sleeper, and this humidifier has never disturbed my sleep. It is much quieter than I expected, especially in sleep mode. In fact, I sleep much better with it on at night since it does a good job in relieving my itchy skin which caused by dryness.

**Q: Can you change the direction of mist output?**
A: Hi,
Yes you can.  There is a straight wide piece that goes across 75% of its total length on the top of the humidifier that  can be moved around in order to change the directional output.  Hope this helps.  Shalom… :O)

### ⭐⭐⭐⭐⭐ Excellent humidifier!
*by A***T on February 12, 2026*

Sturdy humidifier. Easy to set up as well as easy to refill without spilling. It has an adjustable top to choose what direction you prefer the mist to go. I have mine in a fairly large bedroom and the humidifier handles it very well. It is also very quiet instead of making a noise like Niagara Falls like some units do. This is well worth the money.

### ⭐⭐⭐⭐⭐ Compact, Quiet, and Reliable
*by J***D on February 18, 2026*

It's. compact, very quiet, aesthetically appealing, and pumps out water vapor like there's no tomorrow. Am very happy I purchased this with the larger reservoir because it runs for hours before needing to be refilled. And with the cold winter air containing zero moisture, I run this humidifier in my bedroom 24/7 refilling as necessary. It's very easy to set up and put to use, plus the soft blue light is a nice feature in that it can be turned off or on. I would buy this one again.

### ⭐⭐⭐⭐⭐ Excellent humidifier. Need to use treated water to avoid white dust
*by K***S on February 16, 2026*

Works great in main bedroom. Easy to set up. I have been using it for three weeks with distilled water and Pure additives to tap water, and have not experienced white dust except the one time I filled with plain tap water. It is quiet and does not interfere with sleep. The hygrometer seems accurate as I have another hygrometer in the room which registers the same humidity level. It does go through about 1.5 gallons per day on the 3 level. Using the 1 level uses about a gallon of water. I have guitars in the room, which requires humidity around 45-50% and I find this to be useful for this purpose besides improving the air quality.
