Dehumidifier prices range from $150 to $700 for most household models, depending on the size of the space it covers and how much moisture it removes per day

A small portable dehumidifier for a single room or closet typically costs $150 to $300. A mid-sized unit that handles a bedroom or basement runs $300 to $500. Large whole-house or commercial-grade dehumidifiers can reach $600 to $1,200 or more. The price you pay depends mainly on how many pints of water the unit can pull from the air per day — measured as pints per 24 hours — and whether it has features like automatic shut-off, a built-in pump, or smart controls.

Beyond the upfront cost, you will also pay for electricity to run the unit. Most household dehumidifiers use 300 to 700 watts, which translates to roughly $15 to $40 per month if you run it continuously during humid seasons. Some models are more efficient than others, so checking the wattage on the label before you buy can help you estimate your operating costs.

Key Takeaways

  • Small dehumidifiers cost $150 to $300, mid-sized units run $300 to $500, and large units can exceed $600.
  • The main price driver is the unit's capacity, measured in pints of water removed per 24 hours — higher capacity means higher cost.
  • Running a dehumidifier continuously during humid months typically costs $15 to $40 per month in electricity.
  • Features like automatic shut-off, built-in pumps, and digital controls add $50 to $150 to the base price.

How capacity affects what you pay

The pint rating is the single biggest factor in price. A 30-pint dehumidifier (removing 30 pints of water per day) costs roughly $200 to $350. A 50-pint model runs $350 to $500. A 70-pint unit can cost $500 to $700. The reason is straightforward: larger capacity requires a bigger compressor, more refrigerant, and a larger coil, all of which cost more to manufacture.

Matching capacity to your space matters because an undersized unit will run constantly and wear out faster, while an oversized unit wastes electricity. A 30-pint dehumidifier works well for a single bedroom or small basement. A 50-pint unit handles a larger basement or whole first floor. A 70-pint or higher is needed for very damp basements or commercial spaces. If you buy the wrong size, you may end up replacing it sooner or paying more in electricity than you save on the purchase price.

Features that add to the cost

A basic dehumidifier with manual controls and a bucket you empty by hand costs the least. Adding an automatic shut-off (which stops the unit when the bucket is full) adds $30 to $60. A built-in pump that drains water continuously into a floor drain or window adds $80 to $150 — this is worth the cost if you cannot empty a bucket regularly or if the unit sits far from a drain.

Digital controls, a humidistat (which lets you set a target humidity level), and Wi-Fi connectivity add another $50 to $100. Some models include a washable filter, which saves you money on replacements over time. Others have a timer or sleep mode. None of these features change how well the unit removes moisture, but they affect how much work it is to own and operate.

Where to buy and price variation

Dehumidifiers are sold at big-box hardware stores, online retailers, and appliance shops. Prices vary slightly by retailer and by season — units are often discounted in fall and winter when demand drops, and prices rise in spring and early summer when people are preparing for humid weather. Buying in the off-season can save you 10 to 20 percent.

Online retailers often have a wider selection and sometimes lower prices, but you will pay for shipping on a heavy item (dehumidifiers weigh 40 to 100 pounds depending on size). Local stores let you see the unit in person and avoid shipping costs, but selection may be limited. Comparing the total cost — including shipping or tax — across at least two retailers is worth the time before you buy.

Energy efficiency and long-term costs

A dehumidifier's energy use is listed on the yellow EnergyGuide label, which shows estimated yearly operating cost. Two units with the same pint rating can differ by 100 to 200 watts, which adds up over a season. A 50-pint unit rated at 600 watts costs roughly $30 to $40 per month to run. The same capacity at 450 watts costs roughly $20 to $30 per month. Over a six-month humid season, that difference is $60 to $120 — enough to offset a higher purchase price for a more efficient model.

Maintenance also affects long-term cost. Models with washable filters save you $10 to $20 per year on replacements. Units with a pump that drains automatically avoid the wear and tear of constantly moving a heavy bucket. Checking reviews for reliability and warranty length can help you avoid buying a cheap unit that fails after one season.

Renting versus buying

If you need a dehumidifier for only a few weeks or months, renting may be cheaper than buying. Some tool rental shops and home improvement stores rent dehumidifiers for $20 to $40 per week. Renting makes sense if you are dealing with water damage from a burst pipe or flood and expect the problem to be temporary. If you live in a chronically damp climate or have a basement that stays humid year-round, buying pays for itself within one to two seasons.

Before you rent, ask whether the rental includes delivery and pickup, whether you pay for water removal, and what happens if the unit breaks. Some rental agreements charge extra for these services, which can push the total cost close to the price of buying a new unit outright.

Frequently Asked Questions

Is a $200 dehumidifier as good as a $500 one?

Not necessarily. A $200 unit is usually smaller (30 to 40 pints) and suited to a single room. A $500 unit is larger (50 to 70 pints) and handles bigger spaces. If you need 30 pints of capacity, a well-reviewed $200 model will work fine. If you need 70 pints, you have to spend more. The price difference is mostly size, not quality.

Can I save money by buying a used dehumidifier?

Used units are cheaper upfront, but you lose the warranty and cannot know how much life is left in the compressor. If the compressor fails, repair costs $200 to $400 — often more than a new unit. Buy used only if you can test it first and the seller offers a short return window.

Do I need a pump, or can I just empty the bucket?

A pump is convenient but not essential. If your dehumidifier sits near a floor drain, window, or laundry sink, you can drain it manually or with a straightforward hose. If it is in the middle of a basement or far from any drain, a pump saves you from carrying a heavy bucket multiple times a day.

Will a cheaper dehumidifier use less electricity?

Not always. A cheaper unit is usually smaller, so it uses less power because it has a smaller compressor. But a cheap large unit may use more electricity than a more efficient expensive one of the same size. Always check the wattage label, not just the price.

What is the difference between a dehumidifier and an air conditioner?

An air conditioner cools the air and removes some moisture as a side effect. A dehumidifier removes moisture but does not cool the air — it actually produces a little heat. In a damp but cool basement, a dehumidifier is what you need. In a hot, humid room, an air conditioner is more useful.
