Pure Guardian H5225WCA Top Fill Ultrasonic Cool and Warm Mist Humidifier with Aromatherapy Tray Blue

A: Distilled or demineralized water has less mineral content than regular tap water. When used, these water types make your humidifier less likely to expel white mineral dust into your indoor air – and less likely for that dust to invade your lungs. Distilled water is a cleaner alternative to tap water. You can also use filtered water if that is your preference.

A: The unit is very quiet. Even with a water softener, you may find that a decalcification filter or distilled water will be needed as the unit can produce a white dust from the minerals/softener in the water.

A: All of our products are designed for use in the US and Canada only.

A: The warm mist is just slightly warm. The water temperature will not exceed 80 degrees inside the unit and cools rather quickly by the time the mist is released.

A: The humidifier is filter free. We do offer a decalcification filter if you should notice a white dust, and that should last 2-3 months.
