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
