Dehumidifier prices range from $150 to $700 for most household models

A basic dehumidifier for a single room costs between $150 and $300. Mid-range models that handle larger spaces or run more efficiently fall between $300 and $500. High-end units with advanced features, smart controls, or commercial capacity can exceed $700. The price depends on how much moisture the unit removes per day, how large a space it covers, and what features it includes.

Prices vary by brand, retailer, and whether you buy during peak season. Summer months (May through August) tend to have higher prices because demand is greatest. You may find better prices in fall and winter when fewer people are shopping for dehumidifiers.

Key Takeaways

  • Small dehumidifiers for bedrooms or closets start around $150, while units for basements or whole-house use cost $400 to $700.
  • The price reflects the unit's capacity in pints per day — how much water it can pull from the air — which ranges from 30 pints to 70+ pints daily.
  • Energy efficiency ratings (ENERGY STAR certification) add $50 to $150 to the upfront cost but reduce electricity bills over time.
  • Portable units cost less than built-in or ducted models, which require installation and may need a contractor.
  • Buying in fall or winter typically costs less than buying during summer peak season.

How capacity affects what you pay

Pints per day is the measure that drives price most directly. A dehumidifier rated for 30 pints per day (suitable for a small bedroom) costs $150 to $250. A 50-pint model (for a basement or large living space) runs $300 to $450. A 70-pint or larger unit (for whole-house use or very damp conditions) costs $500 to $800.

The pint rating tells you how much water the unit removes from the air in 24 hours under standard conditions. A higher number means the dehumidifier works faster and can handle larger or damper spaces. Buying a unit rated for less capacity than you need means it will run constantly without keeping humidity down. Buying one rated for more than you need wastes money on features you do not use.

Match the pint rating to your space size and how damp it is. A 1,000-square-foot basement with visible moisture needs at least 50 pints per day. A 200-square-foot bedroom with mild mustiness may need only 30 pints per day.

What features add to the cost

ENERGY STAR certification adds $50 to $150 to the price but uses 15% less electricity than standard models. Over five years, the savings on your power bill often cover the higher upfront cost, especially if you run the dehumidifier year-round or in a large space.

Smart controls and Wi-Fi connectivity add $100 to $200. These let you turn the unit on or off from your phone, set humidity targets automatically, and receive alerts when the water tank is full. Basic models have a dial or button and require manual adjustment.

Continuous drain options (a hose connection that lets water drain directly to a floor drain or sump pump instead of filling a tank) add $30 to $80. This is useful if you cannot empty a tank frequently or want the unit to run unattended.

Quieter operation (models rated 50 decibels or lower) costs $50 to $100 more than standard units. If the dehumidifier will run in a bedroom or living space, quieter models are worth the extra cost.

Portable versus installed models

Portable dehumidifiers (the kind you plug in and move between rooms) cost $150 to $600 and need no installation. You can set one up yourself in minutes.

Built-in or ducted dehumidifiers cost $800 to $2,000 plus installation labor ($500 to $1,500). These are mounted in walls, crawl spaces, or HVAC systems and handle whole-house humidity. Installation requires a contractor and may involve running ducts or electrical lines. Choose this route only if you have persistent humidity across multiple rooms or a very large home.

Where to buy and how to find lower prices

Big-box retailers (Home Depot, Lowe's, Walmart) stock 20 to 40 models at any given time and often have sales on seasonal items. Online retailers (Amazon, Best Buy) offer wider selection and sometimes lower prices, but you pay for shipping on heavy units.

Prices drop in September through March when demand is low. If you can wait, buying in fall saves 10% to 25% compared to summer prices. Clearance sales happen in late August and early September as retailers make room for fall inventory.

Refurbished or open-box models cost 20% to 40% less than new units. These are returned items that have been inspected and repackaged. Most come with a one-year warranty. Check the return policy before buying refurbished, since some retailers do not accept returns on discounted units.

Operating costs beyond the purchase price

Electricity is the largest ongoing cost. A standard 50-pint dehumidifier uses about 700 watts and costs $0.08 to $0.15 per hour to run, depending on your local electricity rate. Running it 12 hours a day for six months (a typical damp season) costs $200 to $400 in electricity.

ENERGY STAR models use 15% less, bringing that cost down to $170 to $340 for the same period. Over five years, the difference between a standard and ENERGY STAR unit is $500 to $800 in electricity costs alone.

Water disposal costs nothing if you empty the tank yourself, but it takes time. A 50-pint dehumidifier may fill a 5-gallon tank every 12 to 24 hours in very humid conditions. If you add a continuous drain hose (one-time cost of $30 to $80), you avoid this chore.

Frequently Asked Questions

Is a cheaper dehumidifier worth buying?

Budget models under $200 work for small spaces and light moisture, but they often fail faster and use more electricity. If you need the unit for more than one season, a mid-range model ($300 to $400) usually costs less over time because it lasts longer and runs more efficiently.

Do I need to spend more for a quiet dehumidifier?

Standard dehumidifiers run at 65 to 75 decibels — about as loud as a vacuum. If the unit will be in a bedroom or living room, spending $50 to $100 extra for a 50-decibel model is worth it. For basements or crawl spaces, noise matters less.

What is the difference between a 30-pint and 50-pint dehumidifier?

A 30-pint unit removes 30 pints of water per day and costs $150 to $250. A 50-pint unit removes 50 pints per day and costs $300 to $450. The 50-pint model works faster, covers larger spaces, and handles very damp conditions. Choose based on your room size and how wet the air is, not just on price.

Should I buy ENERGY STAR if I only need the dehumidifier for one season?

If you will use it for one season only, the electricity savings may not offset the higher upfront cost. A standard model is fine for short-term use. If you expect to use it for two or more seasons, ENERGY STAR pays for itself.

Can I return a dehumidifier if it does not work?

Most retailers offer 30 to 90 days for returns on unopened or lightly used units. Once you have run it, some retailers charge a restocking fee of 10% to 20%. Check the return policy before you buy, especially for online orders where shipping costs add up.
