Ion Exchange Filter
It demineralizes and treats water to reduce scale-forming calcium and magnesium from hard water. This prolongs the life of the ultrasonic generator and prevents white dust particles to deposit into the air.
Split Nozzles + 360° Adjustable Direction
A split nozzle for bi-directional mist for wider coverage. Designed for rooms up to 500 sq. ft.
Effectively relieve dry nose, throat lips and itchy skin with the virtually silent Dual Mist Humidifier with ION exchange filter. Will help you breathe easier and sleep more comfortably. This ultrasonic humidifier disperses warm or cool mist. A split nozzle for bi-directional mist for wider coverage. Sleek design with easy to use control knobs. Large, transparent blue water tank with easy-carrying handle. ION exchange filter demineralizes and treats water to remove scale-forming calcium and magnesium from hard water. This prolongs the life of the ultrasonic generator and prevents white dust particles to deposit into the air.
The easiest way to check if the warm mist function is working or not: after the unit runs for 10 mins, turn the power off, lift the water tank and feel the water in the reservoir. The water temperature should be around 100-110 when the ambient temperature is 65 degrees. It varies depending on ambient room temperature. The fan inside the humidifier makes a humming noise when it's functioning.
For the first time use, please allow 5-10 minutes for water going through the filter and filling up the water reservoir after placing the water tank in position. The red light should turn off and the humidifier starts to run.

It puts out a good amount of humidity and is able to keep about 900 square feet at 35-40%, even in January.
Update, 3/2015 - These work about 2 years and then just stop, but it's very good while it lasts. I installed a reverse-osmosis system under my sink and using only that water, the white-dust problem is gone.
With my 3 months old hitting the peak Winter here in Virginia, I was in the market for a good ultrasonic humidifier. I was always fascinated by the Air-O-Swiss models but being way out of my budget started researching on various other alternatives. I must say I was glad to find Sunpentown's SU-4010. The price was right and I thought I will give it a shot.
Unlike my previous Vicks, the construction of this humidifier was very simple. I filled it up, turned it on and there I was with a burst of cold mist. I have been using the humidifier almost daily since almost an year now and very happy with it. It goes down on my list of best value for money items.
-Easy to cleanup daily and effortless maintenance
-Very quiet (now this is a personal perspective so your's might vary)
-Works for both warm and cold mist.
-No issues so far with 9 Months of daily use
-Never experienced any leaking
-The spout has two legs so you can spread them up to direct mist into different directions.
-Good amount of mist produced
-Warm mist not very warm but can be used when you don't want the temperature of the room dropping down because of the humidifier
I put this on, and within only a few hours, The humidity in the room was up to 40%! It topped out at 52% and then I turned it down to half-power and it maintained through the night.
I will definitely be buying a second one so I can have one in each room. This is a lifesaver!
However when working on the unit, I noticed that it was missing a dust filter underneath the machine where air is drawn in. The company offered a replacement filter and door for $8.00 including shipping.
I also had a problem with one of the replaceable water filters that was leaking filter material. The company replaced this defective quickly.
I caution not attempt to open the unit if you are not handy or comfortable making these type repairs as it can be a bit tricky.
All that said, I would recommend this humidifier and appreciate their responsive customer service.
This is a winner!
