4. Product Features
- Efficient Humidification: Utilizes fine spray particles with a 5µm pore diameter and 740 holes for high atomization volume, effectively humidifying the air without wetting surfaces.
- Antioxidant Protection: Constructed from ABS, ceramic, and silicone, with the atomizer surface treated with an antioxidant protective coating for durability.
- High Conversion Efficiency: Features low drive voltage, low power consumption, low impedance, and a stable waveform, ensuring high conversion efficiency.
- Easy Integration: Designed for easy use and installation, primarily for integration into DIY or existing home humidifiers.
- Portable Design: Mini size allows for easy transport and integration into compact devices.
- Timed Shutdown: Supports a 4-hour timed shutdown function for convenience and safety.

5. Setup and Installation
- Prepare the Cotton Stick: Before first use, fully immerse the cotton stick in water until it is completely saturated. This ensures proper water absorption by capillary action.
- Connect the Atomizer Disc: Connect the atomizer disc's wires to the designated connector on the circuit board. Ensure the polarity is correct (red wire to positive, black wire to negative).
- Integrate into Water Reservoir: Place the cotton stick into your humidifier's water reservoir, ensuring it is in constant contact with the water. The atomizer disc should be positioned so that the cotton stick feeds water directly to its center. Important: Do not immerse the atomizer disc directly in water. It operates by capillary action from the cotton stick.
- Power Connection: Connect the circuit board to a 5V USB power source using a Micro USB cable (not included). This can be a phone charger (around 2015 models or newer), a power bank, or a computer USB port.

6. Operating Instructions
- Power On/Off: Once connected to a power source, press the small button on the circuit board to turn the atomization on.
- Mode Selection: Each subsequent press of the button will cycle through the operating modes: ON, OFF, and Intermittent.
- Timed Shutdown: The module is equipped with an automatic 4-hour timed shutdown feature. After 4 hours of continuous operation, the module will automatically turn off.
- Water Level: Ensure the cotton stick remains moist and in contact with water for continuous mist generation.
7. Maintenance and Care
- Cleaning the Atomizer Disc: If mist output decreases, gently wipe the surface of the atomizer disc with a soft cloth or cotton swab dampened with white vinegar to remove any mineral deposits. Rinse with clean water afterward.
- Cotton Stick Replacement: Replace the cotton stick periodically (e.g., every 1-3 months, depending on water quality and usage) or if you notice reduced mist output or discoloration.
- Water Quality: Always use clean, distilled, or demineralized water to prevent mineral buildup on the atomizer disc and prolong its lifespan.
- Storage: When not in use for an extended period, disconnect the power, clean the module, and store it in a dry, cool place.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No mist is generated. | No power, dry cotton stick, atomizer disc clogged, incorrect connection. | Check USB power connection. Ensure cotton stick is fully saturated. Clean atomizer disc. Verify atomizer disc wires are correctly connected. |
| Low mist output. | Mineral buildup on atomizer disc, cotton stick not fully saturated or old, insufficient water supply. | Clean atomizer disc. Replace cotton stick. Ensure cotton stick is properly submerged in water. |
| Module stops after 4 hours. | Automatic timed shutdown feature. | This is normal operation. Press the button to restart the module if desired. |
| Water collects on the surface around the atomizer. | Atomizer disc is immersed in water, not using capillary action. | Ensure the atomizer disc is positioned above the water level and receives water only via the cotton stick. |
