* Correct Humidity Level:
What exactly is relative humidity: Relative humidity is the amount of water vapor in the air, expressed as a percentage
of the maximum amount that the air could hold at the given temperature. We normally mark it with %RH, like 45%RH.
Atmospheric air always contains water vapor, the percentage of which depends on the meteorological conditions. The higher
the temperature is the more the air keeps water vapor. Therefore, we use the concept of „relative humidity”. In winter, when
the cold air is heated up to the comfort temperature, the relative percentage of the water vapor falls which means the relative
humidity drops. In order to keep a comfortable and health environment at home, we need some artificial addition of water or
water vapor to the room air- that‟s air humidification.
Ideal relative humidity levels under different situations.
The most comfortable 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 instruments: 40-60%RH
Library art gallery and museums: 40-60%RH
* Relative Humidity
1. 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. The air contains water mist more or less. The proportion of water mist to the air varies
according to different air temperatures. The higher the temperature, the more water mist inhaled in the air.
2. In winter, the cold air outside enters the room and becomes warmer by the higher temperature in the room. As a result,
the relative humidity decreases. If you want to keep the healthy environmental humidity, we need to increase the mist
volume in the air. The humidifier can do that for us.
3. Relative humidity in different environments suitable for people:
Bedroom, living room: 45-65%RH
Patient‟s room: 40-55%RH
Room with computer, experiment equipment: 45-60%RH
Room with piano: 40-60%RH
Museum, exhibition hall, and library: 40-50%RH
* Water filter
1. Ceramic balls can soften the hard water.
2. Ceramic filter can eliminate the strange smell in the water.
* Aroma box
1. Press out aroma box from the base.
2. Use water-soluble aroma oil and drop on to the sponge.
3. Put the aroma box back into humidifier, the aroma function will remain on when the humidifier is running.
4. To stop the aroma function or when storing the humidifier, clean the sponge in the aroma box.
5. Only drop aroma oil into aroma cotton. Do not drop any liquid except clean water into water tank or basin.
