The fastest places to buy a dehumidifier right now
You can buy a dehumidifier today at big-box retailers like Home Depot, Lowe's, and Walmart, which stock them in-store and online with same-day or next-day delivery in many areas. Amazon and other online marketplaces carry dozens of models with shipping times ranging from two days to two weeks depending on your location and the seller. Local appliance stores and hardware chains often have smaller selections but staff who can answer questions about capacity and noise level. If you want to spend less, Facebook Marketplace, Craigslist, and OfferUp list used units from people upgrading or moving, though you cannot test them before purchase and have no return option.
The choice between these routes depends on what matters most to you: speed, price, selection, or the ability to see and touch the unit before buying. Each has real trade-offs in cost, warranty coverage, and how quickly you can start using it.
Key Takeaways
- Home Depot, Lowe's, and Walmart stock dehumidifiers in-store and online, with many offering same-day or next-day delivery in major cities.
- Amazon and specialty appliance websites carry the widest selection of brands and capacities, but shipping can take one to two weeks depending on the model and seller.
- Local appliance stores and hardware chains usually have smaller inventories but staff who understand capacity ratings and can help match a unit to your room size.
- Used dehumidifiers on Facebook Marketplace, Craigslist, and OfferUp cost 30 to 50 percent less but come with no warranty and no way to return them if they fail.
- Warehouse clubs like Costco and Sam's Club carry a limited selection at lower prices if you have a membership, though availability changes by season and location.
Big-box retailers: fastest for in-store pickup
Home Depot and Lowe's both stock dehumidifiers year-round in their appliance sections, with models ranging from small 30-pint units for bedrooms to large 70-pint units for basements. You can check stock at your nearest store online before you go, and both offer free in-store pickup within a few hours in most locations. If you need it shipped instead, Home Depot typically charges $50 to $100 for delivery and setup, while Lowe's offers free shipping on orders over $45 to many areas.
Walmart carries fewer models than Home Depot or Lowe's, but prices are often lower and they offer same-day delivery through Walmart+ in some cities. Their online inventory is larger than what appears in-store, so check their website first. Return policies at all three retailers are 30 to 90 days, which gives you time to test the unit and make sure it handles your space.
Online marketplaces: widest selection and price range
Amazon stocks hundreds of dehumidifier models from brands like Frigidaire, hOmeLabs, Ivation, and Colzer, with prices from $150 to $600. Shipping is usually two days with Prime membership, though some sellers offer slower shipping at lower prices. Read the reviews carefully — dehumidifiers get complaints about noise, water leakage, and whether they actually reach the advertised pint capacity in humid climates. Amazon's return window is 30 days, and you can return most units for free if they do not work as described.
Wayfair, Best Buy, and Target also carry dehumidifiers online with similar shipping times and return policies. Wayfair often has sales on seasonal items and lets you filter by capacity, noise level, and price. Best Buy stocks some models in-store for pickup and carries extended warranty options if you want coverage beyond the manufacturer's may provide. Prices across these sites are usually within $20 of each other for the same model, so checking multiple sites takes only a few minutes.
Local appliance stores: informed staff and smaller selection
Independent appliance retailers in your area often carry 10 to 20 dehumidifier models and employ staff who understand the difference between pint capacity, energy use, and whether a unit is right for your room size. They can explain why a 50-pint dehumidifier might not work in a 500-square-foot basement if the space is poorly insulated, or why a small 30-pint unit is enough for a bedroom. This information is worth the time if you are unsure what capacity you need.
Prices at local stores are usually 5 to 15 percent higher than big-box retailers, but you avoid shipping costs and can take the unit home the same day. Many local appliance stores offer delivery and setup for $50 to $75, which is cheaper than Home Depot or Lowe's. Return policies vary — ask before you buy — but most allow 30 days. If the store is small, call ahead to confirm they have the model you want in stock.
Used dehumidifiers: lower cost with higher risk
Facebook Marketplace, Craigslist, and OfferUp list used dehumidifiers for $75 to $250, typically 30 to 50 percent less than new. Sellers often list units they no longer need because they moved, upgraded, or solved their moisture problem. The risk is that you cannot test the unit before buying, and once you take it home, you have no recourse if it breaks or does not work. Some sellers will let you plug it in at their house to confirm it runs, but you cannot know if it will continue working after a week or a month.
When shopping used, ask the seller how long they owned it, why they are selling, and whether it has been stored in a dry place. Units stored in damp basements or garages may have rust or mold inside. Request photos of the unit running and the water collection bucket or drain hose. Avoid units with visible corrosion, cracks in the plastic housing, or sellers who cannot explain what the unit does. Bring cash and meet in a public place, and consider asking the seller to demonstrate it working before you hand over money.
Warehouse clubs: limited selection at lower prices
Costco and Sam's Club carry a rotating selection of dehumidifiers during spring and summer, usually two to four models at any given time. Prices are typically $50 to $100 lower than big-box retailers for the same brand and capacity. The trade-off is that you cannot choose from as many options — if Costco stocks only a 50-pint model and you need a 30-pint, you are out of luck. Both clubs offer generous return policies: Costco allows returns for up to two years on most items, and Sam's Club allows 90 days.
Availability changes by season and location, so call your local warehouse or check their website before you go. If you do not have a membership, the cost of joining ($60 to $130 per year) only makes sense if you plan to buy other items there. For a single dehumidifier purchase, a big-box retailer or online marketplace is usually faster and cheaper.
