When shopping for a basement dehumidifier, you should first consider the size of the unit you need. All dehumidifiers are rated by their water removal capacity per day, and these ratings often have corresponding coverage areas measured in square feet. Be sure to also consider the operating conditions under which the capacity rating was determined. Some manufacturers rate their dehumidifiers at saturation, or 100% relative humidity. Others rate them under more realistic AHAM conditions, or 60% relative humidity at 80°F. Knowing this information will help you choose the best unit for your needs and ensure that you achieve optimal results.
