Dehumidifiers range in price from $50 to over $225 at Wal-Mart. For dehumidifiers with ratings of 30 to 70 pints per 24 hours, buyers should expect to spend from $170 to $200 as of 2015.
When buying a dehumidifier, the consumer should consider the size of the room where they plan to use the unit and the humidity level. To reduce the growth of mold and mildew, the dehumidifier should have the capacity to lower the humidity to 50 percent or less. Most models have an automatic shutoff when the reservoir is full. Many machines include an adapter for a drain hose to empty the water the machine collects to a floor drain or sump.
