The increase in portable dehumidifier brands and models on the market demonstrates increased consciousness about the comfort and health of the indoor environment. Elevated indoor humidity is not only uncomfortable for residents, but it also makes air conditioners and furnaces run longer and makes it harder for them to effectively cool or heat the home. High levels of indoor moisture also spawn the growth of indoor mold, mildew, and bacteria. The Environmental Protection Agency (EPA) recommends keeping indoor relative humidity between 30% and 50%.
Major portable dehumidifier brands rate their units according to these criteria:
Home units typically utilize compressors to extract water vapor or, less commonly (and less effectively), a desiccant dehumidifying process.
Dehumidifiers are rated according to total pints of water removed from the air over a typical 24-hour period.
Typical residential requirements for portable units run from 30 pints daily suitable for a damp room of 500 square feet up to 50 pints for 1,000 square feet. In more humid climates, 75-pint models may be utilized for larger rooms of 1,200 square feet or more.
Basic units from most dehumidifier brands require manual emptying of the removable reservoir. Larger units may drain by gravity flow into a floor drain. Full-feature dehumidifiers include pumps to automatically empty the reservoir.
