The 10-hour* Ultrasonic Cool Mist Humidifier guards against problems caused by dry air in the home. Cleanliness matters!

Thanks to ultrasonic technology, it disperses a soothing, cool mist into the air and is ultra-quiet making it ideal to have on while you sleep. It is great for tabletops due to its compact size.
A low water indicator light lets you know when it’s time to refill the water tank and the night light feature makes it a great addition to kids’ rooms! PureGuardian® humidifiers create a better home environment for those suffering from colds, allergies and dry skin.

How It Works
The Guardian Technologies™ PureGuardian® Ultrasonic Humidifier uses a metal diaphragm vibrating at an ultrasonic frequency to create water droplets that are expelled out into the room to help maintain the desired humidity level. An ultrasonic humidifier is virtually silent when operating.
Frequently Asked Questions
Why should I use a humidifier?
People need a certain level of humidity to be comfortable. In the winter, indoor humidity can be extremely low, and the lack of humidity can dry out your skin and mucous membranes. Low humidity also makes the air feel colder than it actually is. Dry air can also dry out the wood in the walls and floors of our houses. As the drying wood shrinks, it can cause creaks in floors and cracks in drywall and plaster. Dry air also increases static electricity.
Does the product require regular cleaning?
It is recommended to wipe out the water tank and base of the product on a regular basis; approximately every 1–2 weeks (depending on use). The Guardian Technologies™ PureGuardian® Ultrasonic Humidifier has Silver Clean™ technology in the water tank, which helps to fight the growth of mold and mildew on the surface of the water tank.
When storing the unit, it is recommended to pour any excess water out and clean it with a soft, damp cloth. Let dry completely before storing.
Are there any wicks or evaporating pads to replace?
There are no wicks or pads to replace.
What is ultrasonic technology?
An ultrasonic humidifier uses a metal diaphragm vibrating at an ultrasonic frequency to create water droplets. Thanks to ultrasonic technology, the Guardian Technologies™ humidifier is virtually silent when running, making it easy to have on while you sleep.
What is Silver Clean™ technology, and why is it used in your humidifier?
Silver Clean™ technology is small particles of silver embedded in the tank to fight the growth of mold and mildew on the surface of the water tank.
Where should I use the product?
It is recommended that you place the product up on a table or nightstand and not on the floor.
What is a comfortable humidity level?
Forty to fifty-five percent (40–55%) humidity is considered within the comfortable range. Any humidity level below thirty percent (30%) is considered dry.
Do I need to put in a certain type of water for my humidifier to work?
You can use either distilled or regular tap water. If you have a high mineral content in your tap water, it may be preferable to use distilled water. Since distilled water is likely to contain lower mineral content than most tap water, it will prevent less build-up.
How long is the warranty?
The warranty is 3-years limited. For detailed warranty specifications, please refer to the warranty section in the instruction manual.

RatingI bought this from target because of how dry it is during the winter and it makes my throat really dry. It lights up blue and looks really awesome at night sorta like a lava lamp. I've had it on entire night and there was still water in it when i woke up. Really cheap and nice humidifier.
RatingVery happy with product. I have a sinus condition and this works wonders
Good for a bedroom, not for larger spaces like living room
RatingThis works well and built to resist micro-organism growth.
I has cool blue light with two speed control. Also you can disconnect from the unit to dump out the remaining of water without unplugging.
I wish it has more than 10 hour while it is running at high humidity.

RatingWe're caring for a young friend this weekend, who arrived with a persistent cough. Sadly, our humidifier for such needs chose that moment to fail, so off I went to Target for an immediate replacement (sometimes even overnight shipping just isn't fast enough.)
Since we are getting older and starting to cut down on "stuff", I wanted something small, just to sit at bedside during an illness, as we already have a whole house humidifier on our furnace.
Of the two small choices, both quite inexpensive, this one both looked much better, and had a much simpler internal layout, which should simplify cleaning. It claims to use "Silver Clean" technology to further minimize cleaning, but comes with a small pick and brush tool, which suggests at least a bit of cleaning can be expected.
Filling was very easy. Remove and invert the blue water tank, unscrew a fill cap, fill with water, screw the cap back on, and invert the tank back into its original position.
I was pleased to see mist coming out of it within seconds of plugging it in and pressing the on button. The mist is easy to direct toward the person it is there to help, and hasn't left any water drops on the furniture yet after an hour of use. It claims to operate up to 10 hours on 0.21 gallons, presumably on low rather than on high, and in a small room. As advertised, it is almost silent in use.
Pushing the button repeatedly chooses the following settings: 1) low power light off, 2) low power light on, 3) high power light on, 4) high power light off, 5) all off.
Power is via a small 110/220 volt (50/60 cycles) wall brick that uses about 60 watts, and delivers 24 volts to the unit. That's vastly more efficient and safer than the steam humidifiers owned previously.
Overall, we are very satisfied.
