Product Information

The 90-hour* Ultrasonic Warm and Cool Mist Humidifier guards against problems caused by dry air in the home.  It features an easy to fill large 1.32-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, which can be extended using the wands.  It is ultra-quiet making it ideal to have on while you sleep.

The humidifier is equipped with the option for warm or cool mist and 3 speed settings.  A low water indicator light lets you know when it's time to refill the water tank.  It also features a soft glow night-light, and a timer.  PureGuardian® humidifiers create a better home environment for those suffering from colds, allergies and dry skin.  Note: Run time is based off of running the unit on low setting and cool mist, also depends on atmospheric conditions.

It is important to only use GENUINE Guardian Technologies™ replacement parts to maintain product performance.

  • 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?
    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 dry completely before storing.

    Are there any wicks or evaporating pads to replace?
    No. 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, allowing you to keep it on while you sleep.

    What is Silver Clean™ technology, and why is it used in your humidifier?
    Unlike other humidifiers that grow slimy mold and mildew, the Guardian Technologies™ PureGuardian® 144-Hour Ultrasonic Digital 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.

So far, it's great.

We've been using it for a few days and it is great. It has a timer which is wonderful as I often forget to switch things off. It also has a nightlight which we like. This has helped as our heating system makes the house so dry.

This works great.

They mean it when they say 90 hours! What a relief to not have to fill a machine over and over. The cool mist is very refreshing and works to combat humidity and helps my kids sleep better. The cord is long and the range great in the 10x12 rooms we use it in. It does come with a mist directed apparatus so it can be pointed at a bed or desk as needed.
