FAQ

Humidifiers

Why should I buy a humidifier?

Humidifiers help make a home or room more comfortable by increasing the humidity level in the

air. Typically, in the colder months humidity levels drop as the colder air cannot hold as much

moisture as the warmer air in the summer months. Humidifiers release a light mist or moisture

into the air that help guard against problems caused by dry air in the home.

What is ultrasonic?

Guardian Technologies™ PureGuardian® humidifiers use 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.

What is a recommended/comfortable humidity level?

A recommended level of humidity for your home is 40–55%.

What is silver doing in my humidifier?

Silver Clean™ technology is a form of micro-silver crystal technology. The silver has been

embedded into the water tank as a fungi-static agent to fight the growth of mold and mildew on

the surface of the water tank. Silver’s antibacterial powers are being applied in a variety of

household and textile products and applications.

Can I add scents, medications, oils, etc. to my water tank?

PureGuardian® Ultrasonic Humidifiers can NOT have scents, medications, etc. added to the

tank. These substances will clog up and prevent the humidifier from functioning properly.

Although, we do sell humidifiers with aromatherapy trays. Aromatherapy tray option helps create

a relaxing environment with essential oils. The humidifiers that include aromatherapy trays are:

H940AR, H965AR, H1210AR, H1250AR, H4750AR, and H4810AR.

What is the difference between warm mist and cool mist humidifiers?

Warm Mist Humidifiers are more frequently used in the winter. The warm mist helps maintain a

warmer temperature in your home during the winter months.

Cool Mist Humidifiers expel a mist that is room temperature. Although the mist and moisture

being distributed is not cold, it may help decrease the temperature in the room that it is in, only

by a few degrees.

Why isn’t the mist warm?

It may take 10-15 minutes before warm humidity is created. The mist may not feel warm due to

the fact it is so fine and is cooled rather quickly from the air in your home. Test by either feeling

the base of the unit which should be warm to the touch or by allowing the unit to run for

approximately 30 minutes on warm setting in a closed 200 sq. foot room or smaller. The room

should feel moderately warmer after 10-15 minutes.

Will my humidifier shut off when the water tank is empty?

Yes. All PureGuardian® Ultrasonic Humidifiers automatically shut off when the water tank is

empty.

Why is my refill light coming on even though there’s water in the tank? There are a few things to check that would cause the empty light to go on: • Please rinse the lid on the bottom of the tank. After you rinse it with warm water, dry it and then push the spring on the outside of the lid, it should move easily. Check the inside of the lid and make sure the rubber gasket is securely in place. When twisting the lid onto the tank, please make sure that it is not over-tightened.

Why is there white dust on my furniture? If water is especially hard or has a high mineral content, you may notice white dust around the unit. White dust is not a problem it is from the minerals in the water that form the dust. The humidifier evaporates the water and then the white dust is left in the unit, not sent out into the air. If bothersome, use distilled water or you can purchase one of our Decalcification Filters (FLTDC, FLTDC20, FLTDC30) to help with the problem.
