FEATURES
water tank is empty
• Noiseless and energy-saving
• High-quality transducer guarantees a lasting and satisfactory function.
• Soothing nightlight
WORKING PRINCIPLE
break up water into tiny water particles with the diameter of about 1-5um.
The ventilation system then blows out this water into the dry air where they
evaporate to give the required humidity. The clearly visible smooth and even
fog can be coming out the unit.
FUNCTION
• To increase and to regulate relative humidity of the room air
• To eliminate electrostatic charges
• To adjust room temperature
CORRECT HUMIDITY LEVEL
The percentage of water mist in a given space with a given air temperature is
named as relative humidity, usually marked as %RH, i.e. 45%RH..
Atomosphereic air always contains water vapor, the percentage of which de-
pends on the meteorological conditions. The higher the temperature is, the
more water vapor the air keeps. When the cold air is heated up to the comfort
temperature level in winter, the relative percentage of the water vapor falls. In
order to keep a comfortable and healthy environment at home, we need some
Ideal relative humidity levels under different situations.
The most comfort RH for human being 45-65%RH
Ideal RH for prophylactic and curative purpose: 40-55%RH
Computer and telecom apparatuses: 45-60%RH
Furniture and musical instrument: 40-60%RH
Library art gallery and museums: 40-60%RH
