WetAir · MH-280
WetAir MH-280 combines a 3.2 L tank, touch controls and a humidity setting. Top filling simplifies refills, while a timer and sleep mode help fit operation around your day.

How it works
An ultrasonic transducer creates fine droplets without boiling the water.
The 3.2 L tank holds water for the MH-280 and supplies its mist-generating area.
High-frequency vibration breaks water into fine droplets; this is not hot steam from boiling.
Droplets leave the unit and evaporate into the surrounding air, adding moisture.
Use the touch controls to select a humidity setting; the reading near the unit can differ from elsewhere in the room.
The resultHumidity gradually rises; reduce output if surfaces become damp or condensation appears.
A humidity setting gives the MH-280 more control than a simple mechanical mist dial. Use a separate hygrometer in the occupied area, away from the direct mist.
The 3.2 L tank fills from the top. Choose the timer, sleep mode or night light to suit your routine, and always switch off before refilling.
Place on a level, stable surface away from electronics and table edges. Unplug before filling and do not exceed the maximum level.
Use the touch controls to select a humidity setting; the reading near the unit can differ from elsewhere in the room.
Check humidity in the occupied area, not directly beside the mist outlet. Keep mist away from walls, fabrics and furniture.
Yes, through the touch controls. Ventilation, temperature and room size also affect the humidity achieved.
Do not add oils or fragrances directly to the tank unless this model’s manual explicitly allows it. Use the recommended water type.
