Safety Information

To ensure safe operation and prevent damage, please adhere to the following safety guidelines:

• Always place the humidifier on a firm, flat, water-resistant surface away from direct sunlight and heat sources.
• Do not place the humidifier near furniture or appliances that are sensitive to moisture.
• Keep the humidifier out of reach of children and pets.
• Unplug the humidifier from the power outlet before filling, cleaning, or moving it.
• Do not immerse the base unit in water or other liquids.
• Use only clean, cool tap water. Distilled or demineralized water is recommended to prevent mineral buildup.
• Do not add essential oils directly into the water tank; use the designated essential oil tray.
• Do not block the mist outlet or air intake vents.
• If the humidifier emits an unusual smell or sound, or if it stops working, unplug it immediately and contact customer support.
• This appliance has a polarized plug (one blade is wider than the other). To reduce the risk of electric shock, this plug is intended to fit into a polarized outlet only one way. If the plug does not fit fully into the outlet, reverse the plug. If it still does not fit, contact a qualified electrician. Do not attempt to defeat this safety feature.
