The main places to buy a dehumidifier
You can buy a dehumidifier at big-box hardware stores, online retailers, appliance specialty shops, and warehouse clubs. The choice depends on whether you want to see the unit in person, need it quickly, or are looking for the lowest price. Each option has a different return policy, delivery speed, and selection of brands and sizes.
Most people start at one of three places: a hardware chain like Home Depot or Lowe's, an online marketplace like Amazon, or a local appliance store. Warehouse clubs like Costco and Sam's Club carry a smaller selection but often at lower prices if you have a membership. Each has trade-offs in cost, convenience, and support.
Key Takeaways
- Hardware stores let you see and compare units in person, ask staff questions, and take one home the same day if stock is available.
- Online retailers offer the widest selection and often the lowest prices, but you cannot inspect the unit before delivery and returns can be slower.
- Appliance specialty stores usually have knowledgeable staff and may offer installation or repair services, though prices are often higher than big-box stores.
- Warehouse clubs like Costco sell fewer models but at discounted prices, and membership is required.
- Return policies vary widely—some stores offer 30 days, others 90 days or longer, so check before you buy.
Hardware stores: Home Depot, Lowe's, and Menards
Home Depot, Lowe's, and Menards stock dehumidifiers year-round, with larger selections in spring and summer when humidity problems peak. You can walk in, see the actual unit, read the label, and ask a staff member about capacity, noise level, and warranty. Most locations have 5 to 15 models on display, ranging from small portable units to larger basement models.
Both Home Depot and Lowe's offer same-day or next-day delivery on many items if you order online and pick up in-store. If you buy in-store, you can take it home when ready. Return windows are typically 90 days, and both stores accept returns without a receipt if you have a credit card on file. Menards runs frequent rebate promotions that can lower the final price by 10 to 15 percent.
Online retailers: Amazon, Walmart.com, and manufacturer sites
Amazon carries the largest selection of dehumidifier brands and models, including units not stocked in physical stores. Prices are often lower than retail locations, and Prime members get free two-day shipping on many items. You can read customer reviews that describe real-world performance in different climates and humidity levels.
Walmart.com and manufacturer websites like Frigidaire.com or LG.com also sell dehumidifiers directly. Shipping times vary—some arrive in two to three days, others take one to two weeks depending on stock and your location. Return policies differ: Amazon typically allows 30 days, Walmart allows 90 days on most appliances, and manufacturer sites vary. The trade-off is that you cannot inspect the unit before it arrives, and if it arrives damaged, the return process can take longer than in-store returns.
Appliance specialty stores and local retailers
Independent appliance stores and regional chains like Best Buy (which carries some dehumidifiers) often employ staff with deeper product knowledge than big-box hardware stores. They can explain the difference between refrigerant and desiccant models, help you choose the right capacity for your space, and sometimes offer delivery and installation services.
Prices at specialty stores are usually 10 to 20 percent higher than hardware stores or online, but you may get better customer service and faster repair support if something goes wrong. Many specialty stores offer extended warranties and will haul away your old dehumidifier. Return policies are typically 30 to 60 days, but this varies by store, so ask before you buy.
Warehouse clubs: Costco and Sam's Club
Costco and Sam's Club carry a limited selection of dehumidifiers—usually two to four models at any given time—but prices are typically 15 to 25 percent lower than hardware stores. Both clubs require an active membership to buy. Selection changes seasonally, with the best inventory in spring and early summer.
Costco offers a 90-day return window and is known for generous return policies even after that period. Sam's Club allows 90 days for most appliances. Both clubs offer delivery for a fee if the unit is too large to carry. If you already have a membership and the model they carry meets your needs, a warehouse club is often the cheapest option.
Comparing price, selection, and return policies
| Retailer Type | Selection | Price Range | Return Window | Delivery Options |
|---|---|---|---|---|
| Hardware stores (Home Depot, Lowe's) | 5–15 models | Mid-range | 90 days | Same-day pickup or next-day delivery |
| Online (Amazon, Walmart.com) | 50+ models | Low to mid-range | 30–90 days | 2–14 days depending on seller |
| Appliance specialty stores | 10–20 models | High | 30–60 days | Delivery and installation available |
| Warehouse clubs (Costco, Sam's Club) | 2–4 models | Low | 90 days | Delivery available for a fee |
What to check before you buy anywhere
Before you complete a purchase, verify the return policy in writing—some stores advertise 90 days but exclude certain items or require the original packaging. Check whether the price includes delivery and setup, or if those are added fees. Ask whether the warranty is the manufacturer's standard coverage or if the retailer offers an extended plan.
If you are buying online, read the shipping details carefully. Some sellers ship from a warehouse and take longer; others ship from a local distribution center and arrive faster. Check the seller's return address and whether they cover return shipping if the unit is defective. If you are buying in-store, ask the staff whether the model you want is in stock or if they need to order it from another location.
Frequently Asked Questions
Can I return a dehumidifier if I open the box but don't use it?
Yes, most retailers allow returns of unopened or opened but unused units within their return window. Home Depot and Lowe's accept returns on opened appliances within 90 days. Amazon and Walmart allow 30 to 90 days depending on the seller. Warehouse clubs are usually the most flexible. Always check the specific retailer's policy before you buy.
Is it cheaper to buy online or in a store?
Online retailers like Amazon and Walmart.com typically have lower prices than hardware stores, sometimes by 10 to 20 percent. Warehouse clubs are often the cheapest if you have a membership. Hardware stores fall in the middle but offer the advantage of same-day pickup. Appliance specialty stores are usually the most expensive. Compare the total cost including delivery fees and tax before deciding.
What if a dehumidifier arrives damaged?
Contact the retailer when ready—do not open or use the unit. Most online retailers will send a replacement or issue a refund if you report damage within a few days of delivery. Hardware stores that deliver will often replace a damaged unit on the spot. Keep the original packaging and photos of the damage as proof. Manufacturer warranties typically do not cover shipping damage, so the retailer is responsible.
Do I need to buy a dehumidifier during a specific season?
Selection and prices are best in spring and early summer when humidity problems are most common. Retailers stock more models and often run promotions during these months. If you need a dehumidifier in fall or winter, selection will be smaller and prices may be slightly higher. Warehouse clubs and online retailers maintain more consistent inventory year-round.
Should I buy from the manufacturer's website or a retailer?
Manufacturer websites sometimes offer exclusive models or bundle deals, but prices are usually the same as or higher than retailers. You lose the option of in-store returns and may have longer shipping times. Buying from a major retailer gives you more flexibility on returns and faster customer service. Check both before you decide, but a retailer is usually the safer choice.
