How the Ultrasonic Cool Mist Technology Works
Ultrasonic humidifiers use vibrations to break water into tiny droplets. These droplets are then released into the air as a cool mist. Unlike steam humidifiers, this process does not use heat, making it safer and more energy-efficient.
Benefits include:
- Quiet operation for undisturbed sleep.
- Cool mist that avoids burn risk.
- Consistent humidity for better comfort.
Unboxing and Assembly
- Open the box carefully. Remove all packaging materials.
- Check the contents to ensure all parts are included: humidifier base, water tank, cap, user manual.
- Place the base on a flat, stable surface.
- Rinse the water tank with clean water before first use.
- Attach the tank to the base without adding water yet.
Filling the Water Tank
- Remove the tank from the base by lifting it straight up.
- Unscrew the cap at the bottom of the tank.
- Fill with cool, clean water. Avoid hot water or water above 104°F (40°C).
- Replace the cap securely.
- Place the tank back on the base. Ensure it sits evenly.
Tip: Using distilled water reduces mineral buildup and prevents white dust.
Operating Instructions
- Plug in the humidifier to a standard 110–120V wall outlet.
- Turn the control dial clockwise to start mist output.
- Adjust mist level to your comfort using the dial.
- The green light means the unit is running normally.
- When the water runs out, the red light comes on and mist stops automatically.
Adjusting Mist Output
- Low setting: Best for smaller rooms or nighttime use.
- Medium setting: Good balance for most situations.
- High setting: Ideal for dry environments or large rooms.
Rotate the mist nozzle to direct moisture where needed. Avoid pointing mist directly at walls or furniture.
