So, What Exactly Does a Humidifier Do?
Humidification is simply, the addition of water into air. Most people require a certain amount of ambient moisture in the air that is not too high and not too low in order to be comfortable.
By increasing the moisture in the air of your home, it provides a more comfortable environment, which makes it easier to breathe and sleep.
And Why do I Need One?
There are several reasons why you should use a humidifier, including the betterment of your health, help with skin and help with the upkeep of your homes wood — just to name a few!
Did You Know?
Humidified air can relieve the discomfort of colds and flu.
Proper humidity levels help to reduce the number of nosebleeds some people are prone to in the dry, winter months.
During the dry, winter months, keeping humidity levels up in the home (between 40–50%) makes the air feel warmer. This can mean you'll run your heat a bit less and save money on your bills!
Why Ultrasonic?
- Ultrasonic Humidifiers produce mist by using a metal diaphragm vibrating at high frequency.
- The water molecules that are produced are extremely small, about one micron in diameter.
- The mist is almost immediately absorbed into the air.
- Because this type of humidifier does not use a fan, it is very quiet when operating.

It does the job for our medium sized bedroom in middle or high setting and is whisper quiet.
These are the two most important characteristics you need for this type of unit.
The thirty hour designation refers to the low setting, which may or may not do the job for you, we rarely use it.
At high, it lasts the night, then needs a refill, which is just as well as I believe it should be cleaned at least every other day, rather than once a week as recommended by the mfg.
On the middle setting expect about 14 hours or so.
While refilling, you can jiggle the body and add a little more water to its capacity.
When placing the tank on the base, had to "search" for the correct placement, solved this by making a verticle mark on the bottom of the tank and aligning it with the vertical mark on the base power button. Once the tank is in place, the mark does not show.
Cleanup, is a snap, all the surfaces can be reached and cleaned quickly, the included brush, secured in the base, helps.
The night light looks attractive and is a well insulated LED and should last.
Functional, attractive, easy to handle and maintain, not expensive, make this a winning unit.
It has three setting a low, medium, and high. You can also turn on a nightlight that lights up the tank blue. It is very quite, we have used all three settings. On the low setting with a normal nights 7-8 hours of sleep we can fill it every other day. On the high setting you will have to refill it in the morning. We only run ours at night or when we are home. I reccomend cleaning the base once a week as it gets alittle gross from the water. I was concerned because when running it gives off a white mist. We had a humidifier do that before and the house was filled with white dust. This one isn't as bad after over a month of use I am just starting to see a white dust on glass and plastic. Overall great purchase.
UPDATE: MARCH 2020 - I bought two of these in 2016 and one died, and one is still going strong. I have not problems cleaning the entire unit -with the exception of that sharp edged inside of the white top cap!
I am purchasing another one today, and don't even want to look at other models; this doesn't have the 'highest' rating, but it has performed EXCELLENTLY for me. This is a verified multiple purchase, and I don't get anything from the maufacturer. Just happy to write an honest GOOD review about a good product.
update: 12/2020: after trying several other brands (higher priced as well) we're back to gettin two more of these(!); fingers crossed they work as previous purchases. (4 years perfect; used in NE winters oct - may)
I had this thing opened up and turned every which way for 3 weeks. Warm room, cold room, direct sun, shadow, upside down, rightside up, sideways nothing helped. It was always covered in moisture and condensation inside.
One other minor thing, the tool compartment and various depressions in the base also get flooded by water during use so you have to be able to unplug it and take the entire unit to the sink to empty when done not just the tank.
Trying to move a 600 pound peice of furniture to unplug this multiple times a day is just a non starter for me and I have nowhere else to put it.
