Product Information

The 100-hour* Ultrasonic Warm and Cool Mist Humidifier guards against problems caused by dry air in the home.  It features an easy to fill large 1.5-gallon tank, ideal for use in medium sized rooms. 

Cleanliness matters! Unlike other humidifiers that grow slimy mold on the water tank surface, Silver Clean™ Protection is embedded in the tank to fight the growth of mold and mildew on the surface of the water tank. Thanks to ultrasonic technology, it disperses a fine mist into the air, and is ultra-quiet making it ideal to have on while you sleep.

The humidifier is equipped with the option for warm or cool mist, a night-light and variable mist control.  A low water indicator light lets you know when it's time to refill the water tank.  PureGuardian® humidifiers create a better home environment for those suffering from colds, allergies and dry skin. Order yours now! 

Note: Run time is based off of running the unit on low speed, also depends on atmospheric conditions.

  • 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 skin and mucous membranes. Low humidity 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?
    Regular cleaning is recommended; approximately every 1–2 weeks (depending on use). When storing the unit, it is recommended to pour any excess water out and clean it with a soft, damp cloth. Let unit dry completely before storing.

    Are there any wicks or evaporating pads to replace?
    No. There are no wicks, pads or filters to clean or 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?
    Unlike other humidifiers that grow slimy mold , the PureGuardian® Ultrasonic Humidifier uses Silver Clean™ technology 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 and not on the floor. Placing it on a table or nightstand during operation is suggested.


    What size room will the humidifier work in?
    Thanks to the adjustable spray feature, this humidifier works well in both large and small rooms.

    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.

    How do I choose warm or cool humidification?
    Choosing warm or cool humidification is based on your preference. Warm moisture tends to make the air in the room feel warmer due to the warm vapor being released into the air. In contrast, cool moisture generally has the opposite effect, causing the air to feel cooler.

    Therefore, if you live in a warm climate, you may prefer a cool moisture humidifier, while those who live in colder climates may prefer a warm moisture humidifier.

    Do I need to heat the water first if I want to have warm humidification?
    No. It is recommended to put room temperature water into the tank for humidifying. The Guardian Technologies™ humidifier will heat and maintain the water temperature for warm humidification.

    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.

Great product and early delivery

Product was exactly what we wanted and works great. Arrived ahead of schedule which was a bonus.

By: dryair

Tank needs redesign.

Unit seems to work very well. Tank is awkward to handle when refilling and a concern is possible damage to the humidity spout when placing tank in kitchen sink. Full tank at full 'throttle' (warm) is good for maybe 10 hours.

By: ditto204


One thing that will help a lot is to purchase the replacement filters and change them every year. I always keep a spare.

Great humidifier

I purchased several humidifiers this season, and this is by far the best one. A tank lasts longer than the others with similar capacity yet it is more effective (even though we have a very large bedroom). I used to own a larger model from pure guardian which stopped producing steam after 2/3 years, so we will see how long this one lasts but so far I highly recommend this model.

Great product!

This is a great product! We have been very happy with it. I just logged in to purchase another one for my parents.

By: Readerease

So far — great

Expensive yet appears after 30 days use to be worth the money. Quiet, efficient and easy to use, good product

By: Grace Martinsen


I read many reviews before purchasing and felt I had picked the best product.
It has totally lived up to my expectation of excellence.
There are no filters or extra parts to buy as with other humidifiers.
The tank is easy to refill and light enough when it's full to where I can easily carry it.
After a month of nearly continuous use, I couldn't be happier with this product.

Exactly what I was looking for

This humidifier was exactly what I was looking for! I love that it gives you the option of having warm or cool mist. It's the perfect size to sit on top of your dresser or side table! It looks sleek and stylish and does not make a whole lot of noise. I keep mine in my bedroom and it works wonders when I'm sick. You just have to make sure to check the light that tells you when to refill the unit with water. I've gotten Guardian products before and have never had any issues with them. I highly recommend this product!
