The main places to buy a dehumidifier
You can buy a dehumidifier at big-box retailers like Home Depot, Lowe's, and Walmart; online marketplaces like Amazon; appliance specialty stores; and directly from manufacturers. Each option has different inventory, pricing, and return policies, so the best choice depends on whether you want to see the unit in person, need it quickly, or are looking for a specific brand or size.
Most dehumidifiers cost between $150 and $500 for portable units that handle a single room, though larger or commercial-grade models run higher. Prices and availability vary by season—demand peaks in spring and summer when humidity problems are most noticeable, so you may find better selection and pricing in fall and winter.
Key Takeaways
- Home Depot and Lowe's stock dehumidifiers year-round in-store and online, with same-day or next-day delivery options in many areas.
- Amazon and other online retailers often have the widest selection and competitive pricing, but you cannot inspect the unit before purchase.
- Appliance specialty stores and local HVAC dealers may carry commercial-grade or high-capacity models not found at general retailers.
- Manufacturer websites sometimes offer direct sales with warranty information clearly stated and occasional bundle deals.
- Return policies vary widely—Home Depot and Lowe's typically allow 30 to 90 days, while Amazon's return window depends on the seller.
Home Depot and Lowe's: In-store and online options
Home Depot and Lowe's both carry dehumidifiers in their appliance sections year-round, with inventory ranging from basic 30-pint models to larger 70-pint units. You can browse in-store to see the actual size and weight, read the label specifications, and ask staff questions about noise level or energy use. Both retailers also let you order online and pick up the same day at many locations, or have it delivered within a few days.
Home Depot's website lists dehumidifiers by capacity (measured in pints per day), brand, and price range, making it straightforward to filter. Lowe's offers similar filtering and includes customer reviews on each product page. Both stores have return windows of 30 to 90 days depending on the item, so you can test a unit and send it back if it does not meet your needs. Check your local store's inventory online before you go, since stock varies by region and season.
Amazon and other online marketplaces
Amazon carries hundreds of dehumidifier models from brands like Frigidaire, hOmeLabs, Eva-Dry, and Ivation. Prices are often competitive, and you can read customer reviews that mention real-world performance in humid basements, bathrooms, or bedrooms. Prime members get free two-day shipping on many units, and some items may have access to for same-day delivery in major cities.
The trade-off is that you cannot inspect the unit before it arrives, and return policies depend on the seller—Amazon's own returns are usually 30 days, but third-party sellers may have shorter windows. Check the seller's return policy and the product's condition when it arrives, since dehumidifiers are heavy and can be damaged in transit. Other online marketplaces like Walmart.com, Target.com, and Best Buy also stock dehumidifiers with similar shipping and return options.
Appliance specialty stores and HVAC dealers
Local appliance stores and HVAC contractors often carry commercial-grade or high-capacity dehumidifiers that big-box retailers do not stock. These units are useful if you have a large basement, a whole-house humidity problem, or need a dehumidifier that integrates with your existing HVAC system. Staff at these stores typically have deeper knowledge of how dehumidifiers work with your home's heating and cooling setup.
Prices at specialty stores may be higher than big-box retailers, but you get personalized information and sometimes installation or maintenance services. Some HVAC dealers rent dehumidifiers for a few weeks if you want to test one before buying, which can be worth the cost if you are unsure whether a portable unit will solve your problem. Search online for "appliance store near me" or "HVAC contractor" plus your city to find local options.
Manufacturer websites and direct sales
Brands like Frigidaire, Danby, and Soleus Air sell dehumidifiers directly through their websites. Buying from the manufacturer means you see the full warranty details upfront, and some offer bundle deals—for example, a dehumidifier plus a water pump or drain hose kit. Shipping times vary, so check before you order if you need the unit quickly.
Manufacturer websites sometimes have models or colors not available at retailers, and customer service can answer technical questions about your specific unit. However, return policies are stricter than at big-box stores—many manufacturers allow 14 to 30 days, so read the policy carefully before checkout.
Seasonal availability and timing
Dehumidifier inventory peaks in spring and early summer when homeowners notice moisture problems in basements and crawl spaces. If you shop during these months, you will find the widest selection but may pay higher prices. Fall and winter inventory shrinks, but prices often drop because demand is lower—if your humidity problem is not urgent, waiting until October or November can save money.
If you need a dehumidifier in winter, check online retailers first, since they maintain inventory year-round even when local stores are out of stock. Some retailers also run sales around major holidays like Black Friday or after-Christmas clearance, so setting a price alert on Amazon or checking Home Depot's website weekly can help you catch deals.
What to check before you buy
Before ordering, confirm the dehumidifier's capacity in pints per day—a 30-pint model works for small rooms, while a 50 to 70-pint unit handles larger basements or whole floors. Check the noise level in decibels if you plan to run it in a bedroom or living space; most portable units range from 45 to 55 decibels. Look at the water tank size (measured in gallons) or whether the unit has a continuous drain option, since emptying a small tank frequently becomes tedious.
Read the warranty terms on the product page or manufacturer website—most dehumidifiers come with a one-year parts and labor warranty, though some offer longer coverage. Check the return policy of the specific retailer or seller, not just the brand, since policies vary. If you are buying online, look for units with high customer ratings and read reviews that mention humidity levels in spaces similar to yours.
Frequently Asked Questions
Can I return a dehumidifier if it does not work for my space?
Yes, most retailers allow returns within 30 to 90 days if the unit is unused or in original condition. Home Depot and Lowe's typically offer 90 days; Amazon's window is usually 30 days but varies by seller. Check the specific retailer's policy before you buy, and keep the receipt and original packaging in case you need to return it.
Is it cheaper to buy online or in-store?
Prices are usually similar across retailers, but online marketplaces like Amazon sometimes have lower prices because they have fewer overhead costs. Big-box stores occasionally run sales or price-match competitors, so it is worth checking both. Factor in shipping costs if you are buying online—a heavy dehumidifier can cost $20 to $50 to ship, which may offset a lower purchase price.
What size dehumidifier do I need?
Capacity is measured in pints per day—how much water the unit removes from the air. A 30-pint dehumidifier works for small rooms or bathrooms; 50 to 70-pint units handle basements or large living spaces. Check the product description or manufacturer specs for the recommended room size, and read customer reviews from people with similar spaces to yours.
Do I need to buy a water pump or drain hose?
Most portable dehumidifiers come with a water tank you empty by hand, but you can buy a separate pump or continuous drain kit to run water directly to a floor drain or window. These accessories cost $20 to $50 and are sold separately at the same retailers where you buy the dehumidifier. Check whether your unit is compatible before you order.
What is the warranty on a new dehumidifier?
Standard warranties cover parts and labor for one year from the purchase date. Some brands offer extended warranties for an additional cost, and a few high-end models include longer coverage. Read the warranty terms on the product page or manufacturer website before you buy, and keep your receipt as proof of purchase.
