Your home's humidity level should be maintained in air conditioned homes to prevent health issues that are associated with dry air. Humidity is the level of water vapor that is present in the air circulating inside the house. Different rooms may have different humidity levels. You can determine your room's humidity level through a device called a hygrometer, which can be purchased cheaply from many discount, hardware, and department stores. With the hygrometer, you will be able to identify which part of the house has poor humidity level.
