Preparing the Humidifier: Place the humidifier on a flat, stable surface near an electrical outlet. Ensure the water tank is clean and free from any residue. Filling the Water Tank: Remove the water tank from the humidifier base. Open the tank's lid or top cover. Fill the water tank with clean, cool, and preferably distilled water. Avoid using hot or boiling water. Be mindful not to overfill; there is often a maximum fill line indicated on the tank. Optional Aromatherapy: Add a few drops of your preferred essential oil to the tray. Do not directly add the oil to the water tank. Assembling the Humidifier: Place the filled water tank back onto the humidifier base, ensuring it is securely seated. Powering On the Humidifier: Turn the dial to "on" to power up. You can adjust the flow level depending on the room size. Powering Off and Refilling: When the water level in the tank is low, the humidifier may automatically shut off, or you can turn it off manually. To refill the tank, power off the humidifier, unplug it, and follow steps 2-4 again.
