Drier air offers greater comfort at higher room temperatures. Lower humidity reduces growth of mold, fungus and bacteria, while creating a conductive environment for storage of most applications. Bacteria & mould requires a high humidity to survive and multiply. If the humidity is kept below 70 % RH, this will not occur.
Relative Humidity is a measure of how much moisture is in the air. It is the ratio that indicates the ability of the air to absorb more moisture, expressed in percent (%RH). The lower the percent, the lower the moisture content in the air and the greater the air’s ability to absorb more moisture. When the air reaches 100% RH, it reaches its satu-ration point and the water vapor turns to liquid, forming droplets of condensation.
