Humidity is the amount of water vapor in the air. It is an important factor in determining the comfort level of a space, as well as the health of its occupants. High humidity can lead to mold growth, dust mites, and other allergens, while low humidity can cause dry skin, eyes, and throats.
There are several ways to check the humidity in a space. One common method is to use a hygrometer. Hygrometers are relatively inexpensive devices that can be purchased at most hardware stores. They measure the relative humidity, which is the amount of water vapor in the air compared to the maximum amount of water vapor that the air can hold at a given temperature.
