    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 120-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 humidity is considered within the comfortable range. Any humidity level below thirty percent 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.
