A:Answer The Frigidaire dehumidified allows you to adjust RH (relative humidity) level. There is not just one ideal year-round indoor humidity level; however, people are typically comfortable with a RH in the 30 to 50 percent range and can tolerate 20 to 60 percent. The ideal RH depends whether you live in the North or South, and it changes with the seasons. High RH is often a summertime problem in the South and excessively low or high RH may create wintertime problems in the North.
Controlling humidity lowers your utility bills by allowing you to set the furnace or central air conditioner thermostat down or up respectively. It also creates a healthier indoor environment. Although overly humid air creates the most health problems, some harmful microbes thrive better in very dry air.
