When it comes to your home, Relative humidity (RH) levels can play a major role in your health. While humidity is the amount of water content in the air, relative humidity is when moisture in the air is relative to the temperature. RH is expressed as a percentage of the total amount of moisture the air can hold.
At 100 percent relative humidity, the air volume is saturated with moisture, meaning the moisture in the air has reached capacity, and the vapor will condense into liquid. The environment is uncomfortably humid. In keeping skin and respiratory irritations at bay, you will be most comfortable between 40 and 60 percent relative humidity.
In the following infographic, Groundworks looks at how to create a comfortable home humidity scale.
