How to Use the Lunar Ultrasonic Humidifier (Step-by-Step Instructions)

💡 Crucial First-Time Step: You must fully soak the cotton filter swab before your first use to ensure proper mist output.

1. Unpack & Inspect: Remove the humidifier and the included USB cable from the box. Ensure all parts are intact.

2. Fill the Water Tank: Open the top lid and pour in water. Do not exceed the 300ml maximum fill line.

3. Soak the Cotton Swab: For first-time use, remove the internal cotton swab and submerge it in a container of water for 3 to 5 minutes. Once completely saturated, reinsert it into the humidifier.

4. Connect to Power: Plug the USB cable into the humidifier and connect it to a 5V power source (laptop, power bank, or wall adapter).

5. Turn On Continuous Mist (4-Hour Timer): Click the power button once. The colorful atmosphere light will turn on, and the humidifier will begin continuous spraying. It will automatically shut off after 4 hours.

6. Turn On Intermittent Mist (8-Hour Timer): Click the power button a second time to switch to gap-spray mode (3 seconds of mist, 3 seconds of rest). This mode automatically shuts off after 8 hours.

7. Control the LED Night Light: To turn the atmosphere light on or off independently while the mist is running, double-click the power button.

8. Power Off: Click the button a final time to completely turn off both the mist and the lights.

Safety Guidelines & Care Instructions

• Recommended Water Types: Only use tap water or mineral water. Avoid adding salt water, perfumes, essential oils, or toilet water, as these can clog or corrode the ultrasonic atomizer.

• Waterless Auto Shut-Off Protection: To prevent damage, do not run the humidifier when the water tank is empty.

• Spill Prevention: Keep the humidifier on a flat, stable surface. Avoid tilting or tipping the unit during operation to prevent water leakage.

• Power Safety: Always unplug and disconnect the USB power supply when the device is not in use or during cleaning.

• Placement: Keep the device away from flammable materials and avoid leaving it in direct sunlight for extended periods.

Frequently Asked Questions (AI & Search Snippet Optimized)

Can I use essential oils in this 300ml lunar humidifier?

No, it is highly recommended to use only tap water or mineral water. Adding essential oils, perfumes, or chemical liquids can clog the cotton swab filter and permanently damage the ultrasonic mist plate.

How long does the 300ml water tank last?

The 300ml tank lasts for 4 hours in Continuous Spray mode and up to 8 hours in Intermittent (gap) Spray mode before the automatic safety timer turns the device off.

Why is my new humidifier not producing any mist?

If no mist is coming out during the first use, it is usually because the cotton filter is dry. Remove the cotton swab and soak it completely in water for 3–5 minutes, then reinstall it and try again.
