Working Principle: Ultrasonic Humidifier use the ultrasonic high-frequency oscillator to
break up water into tiny water particles with the diameter of about 1-5um.The ventilation
system blows out this water into the dry air where they evaporate to give the required
humidity.

Features:

High efficient in humidification with large output.
Low energy consumption, save 85-90 percent of electricity of normal stream humidifier.
Long lifetime
Automatic control to humidity level, lack-water security protection.
Heating Function: Touch the symbol of Heating to make warm mist. Press again to stop the
heating function.
Ozone(Anion): Touch the symbol of Ozone(Anion) to spread a number of ozone (Anion)
elements. Press again to stop the Ozone(Anion) function.

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 depends 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 artificial
addition of water vapor to room air.
• 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

Water filter:

1.The plastic part is mixed with NANO-SILVER material to prohibit the bacterium.
2.Ceramic balls can soften the hard water.
3.Ceramic filter can eliminate smells in the water.
