What It Costs to Run
Power use depends on the unit and the room. Read the watt label on your model. For a simple example, a 500 watt unit that runs 8 hours a day uses 4 kilowatt hours. At 17 cents a kilowatt hour that is about 68 cents a day, or about $20 a month. A unit that is the right size for the room cycles off and costs less. A unit that is too small runs all day.
Energy Star models use less power for the same pints. The Midea 22 and Midea 50 are Energy Star models, per their listings.
Looking ahead, dehumidifier prices are splitting in two. Basic compressor units stay in the $130 to $300 range, while smart units with Wi-Fi, pumps and Energy Star Most Efficient labels climb higher. Newer efficiency rules mean better models use less power per pint. The catch is that a cheap unit can cost more in the end if it wears out early or runs all day in a cool room.

The risk to watch is the hidden cost. A unit that is too small runs nonstop, and that shows up on the power bill. A unit that is too big short cycles and wears out. Cheap listings also hide small tanks and no drain option. Expect more bundles with pumps and filters sold at a markup. Add up the purchase price, the power and the filter, not just the sticker.
Other Costs to Count
- Filter: most are washable. Clean it every few weeks.
- Drain hose or pump: a hose is often included. A built-in pump raises the price, as the pump models above show.
- Repairs and life span: compressor units often last several years. Cheap units can fail sooner, so check the warranty.
- The wrong size: the most expensive mistake. Use the dehumidifier pint calculator and read how to choose the right size dehumidifier.
How to Spend Less
- Pick the right size first. See the dehumidifier buying guide.
- Pick a unit with a hose drain if the room has a floor drain.
- Set the humidity to 45 to 50 percent. Lower wastes power.
- Shop on rating counts. A unit with thousands of ratings is a safer buy than a cheap unit with a few.

FAQ
What is the cheapest dehumidifier worth buying?
A mini unit for a closet costs under $60. For a real room, a full-size compressor unit starts at about $130.
How much does a dehumidifier add to the power bill?
A typical 500 watt unit running 8 hours a day costs about $20 a month at 17 cents a kilowatt hour. Your rate and unit will change this.
Is a whole-house dehumidifier worth the price?
Only for a large, humid home with a ducted system. It costs well over $1,700 before installation.
Final Word
Buy the right size, a drain you will use and a unit with a track record. That keeps the total cost down more than a low sticker price does.
What happens next: expect steady prices for basic models and rising prices for pump and smart models. Spend where it helps, in the right size and a drain you will actually use.
