How it works
From tank water to a fine mist
An ultrasonic transducer creates fine droplets without boiling the water.
Water reaches the transducer
The 4.5 L tank holds water for the MH-410B and supplies its mist-generating area.
Vibration creates mist
High-frequency vibration breaks water into fine droplets; this is not hot steam from boiling.
Mist enters the room
Droplets leave the unit and evaporate into the surrounding air, adding moisture.
Settings adjust delivery
Four MH-410B output levels vary the mist, with the display showing the selected settings.
The resultHumidity gradually rises; reduce output if surfaces become damp or condensation appears.
A water reserve for your chosen setting
The tank holds 4.5 L, but refill frequency depends on the selected level. Lower output uses water more slowly; judge the result by humidity rather than the amount of visible mist.
Look after the ceramic water filter
The water filter is separate from the ultrasonic transducer. Follow the care instructions for both; a filter does not remove the need to clean the tank and replace the water.
Getting started
Position and fill
Place on a level, stable surface away from electronics and table edges. Unplug before filling and do not exceed the maximum level.
Choose the settings
Four MH-410B output levels vary the mist, with the display showing the selected settings.
Check the humidity
Check humidity in the occupied area, not directly beside the mist outlet. Keep mist away from walls, fabrics and furniture.
Your questions answered
How many mist levels does the MH-410B offer?
Four. Use a lower level if humidity is already sufficient or nearby surfaces start to become damp.
Can I add essential oils to the water?
Do not add oils or fragrances directly to the tank unless this model’s manual explicitly allows it. Use the recommended water type.
