Product Overview

The 120-hour* Ultrasonic Warm and Cool Mist Humidifier guards against problems caused by dry air in the home.  It features an easy to fill large 2-gallon tank, ideal for use in large 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 warm or cool mist into the air, which can be extended using the wands.  It is ultra-quiet, making it ideal to have on while you sleep. Smart mist sensor monitors the level of humidity in the room and adjusts to your selected level.

The humidifier is equipped with an easy to use digital display, a night-light, timer and 3-speed 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 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®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.
