What is the average cost of a basement dehumidifier?

The average cost for a basement dehumidifier is between $200 and $300 as of 2015, according to CostHelper. Basement dehumidifiers are generally the largest capacity dehumidifiers and remove 25 to 75 pints of water every 24 hours.

A basement is generally one of the largest and dampest areas of the home. A dehumidifier for the basement has a larger tank and most have attachments to allow them to connect directly water pipes. This requires less-frequent maintenance, such as emptying the tank. A large capacity dehumidifier generally uses between 1.5 and 1.7 kilowatt-hours of electricity, according to the U.S. Department of Energy.
