Full Answer

Humidity is a measure of how much moisture is in the air compared to the maximum amount possible. This measurement is typically given in terms of a percentage, rarely as a ratio or fraction. Low humidity in the air, otherwise known as dry air, can exacerbate many respiratory conditions. It can lead to dry lips and skin, nose bleeds and even the common cold. A humidifier can increase the humidity of the air to improve comfort and respiratory health.

A humidifier must be cleaned regularly to prevent the growth of mold and bacteria in the device, which will be blown around the house. If moisture is found on windows and other surfaces, the appliance should be turned off to prevent contamination.

    Cold fronts move faster than warm fronts because their cooler temperature increases the density of the air and concentration of molecules. Warm fronts are sometimes nearly motionless when cold fronts take them over. This cold, heavy air mass lifts the warm front out of the way.
