Yes, Costco carries dehumidifiers, but selection and availability change by location and season
Costco sells dehumidifiers year-round, though the models available depend on which warehouse you visit and the time of year. The selection is typically largest in spring and early summer when humidity problems peak in most regions. You can find dehumidifiers in the appliances section of your local Costco, or you can browse their current inventory online at Costco.com and check whether a specific model is in stock near you.
Costco's dehumidifier lineup usually includes mid-range units from brands like Frigidaire, LG, and Ivation. These are not the cheapest dehumidifiers on the market, but they tend to be well-reviewed models that balance capacity, noise level, and energy use. Costco's return policy—which allows returns within a reasonable timeframe on most items—means you can test a unit at home and send it back if it does not perform as expected in your space.

How to find dehumidifiers at your local Costco
Walk into the appliances section of your warehouse—this is where Costco displays dehumidifiers alongside air purifiers, fans, and other climate-control equipment. If you do not see any units on the floor, ask a warehouse employee whether they have stock in the back or whether the item is currently out of stock. During slower seasons, dehumidifiers may be stored off the sales floor and brought out only when you request them.
If you prefer to shop from home, visit Costco.com and search for "dehumidifier." The website shows you which models are available for delivery to your address or for pickup at your local warehouse. Availability varies significantly by region—a model available in California may not be stocked in the Northeast. Costco.com also displays the current price and customer reviews, which can help you compare capacity and noise ratings before you commit.
What dehumidifier models Costco typically stocks
Costco's dehumidifier inventory shifts throughout the year, but you can usually find units in the 30-pint to 70-pint range. A 30-pint dehumidifier removes 30 pints of moisture from the air per day and works best in small rooms or basements under 500 square feet. A 50-pint or 70-pint unit handles larger spaces, whole basements, or very humid climates. Costco rarely stocks the smallest (20-pint) or largest (90-pint+) models, so if you need an extreme size, you may need to shop elsewhere.
Frigidaire and LG models appear most often in Costco warehouses. These brands offer straightforward controls, built-in pumps or bucket drainage, and energy ratings that help you estimate monthly operating costs. Some Costco locations also carry Ivation or other specialty brands, but this varies. Check your local warehouse or Costco.com to see what is currently available in your area.
Pricing and how Costco dehumidifiers compare to other retailers
Costco dehumidifiers typically range from $200 to $500, depending on capacity and features. A 30-pint unit usually costs $200 to $300, while a 50-pint or 70-pint model runs $350 to $500. These prices are competitive with Amazon and big-box retailers like Best Buy, though you may find lower prices on older or discontinued models at Walmart or Home Depot during sales.
The real advantage of buying at Costco is not always the lowest price—it is the combination of a solid warranty, customer reviews visible in the warehouse, and the ability to return the unit if it does not work in your home. If you are a Costco member and the model in stock meets your needs, the convenience and return flexibility often outweigh a $20 to $50 price difference elsewhere.
When to buy a dehumidifier at Costco
Spring and early summer (March through June) is when Costco stocks the widest range of dehumidifiers. If you wait until July or August, selection shrinks as demand drops and warehouses clear inventory. By fall and winter, many locations carry only one or two models, if any. If you know you need a dehumidifier, shopping in April or May gives you the best choice of sizes and brands.
That said, if you discover a moisture problem in your basement in September, do not assume Costco is out of options. Call your local warehouse or check Costco.com to see what is in stock. Some regions with humid climates year-round maintain better dehumidifier inventory through the fall and winter months.
Costco membership and online ordering
You must have a valid Costco membership to shop in the warehouse or to see prices on Costco.com. If you do not have a membership, you can still browse the Costco website without logging in, but you cannot see prices or place orders. A Gold Star membership (the basic tier) costs around $65 per year and includes access to all appliances and general merchandise.
If you order a dehumidifier online through Costco.com, you can choose warehouse pickup or home delivery depending on the model and your location. Pickup is usually free for members, while delivery costs vary by distance and item weight. Check the shipping cost before you complete your order, as it can add $30 to $100 to the total price for a heavy dehumidifier.
What to check before you buy
Before you take a dehumidifier to the register, confirm the pint capacity matches the size of the space you want to dry. A 30-pint unit in a 1,000-square-foot basement will run constantly and may not keep up. A 70-pint unit in a small bedroom will cycle on and off frequently and waste energy. Read the product tag or ask an employee for the square footage range the unit is designed for.
Also check whether the dehumidifier has a built-in pump or requires manual bucket emptying. A pump automatically drains water to a floor drain or window, while a bucket model requires you to empty it by hand every few hours in very humid conditions. If you do not have a drain nearby, a pump model saves you significant work. The product description on Costco.com or the tag in the warehouse will state which type you are looking at.
Frequently Asked Questions
Can I order a dehumidifier from Costco online if I do not have a membership?
No. You must have an active Costco membership to purchase anything through Costco.com or in a warehouse. A Gold Star membership (the basic tier) costs around $65 per year. Some Costco locations offer a one-day trial membership, but you cannot use it for online purchases.
What is Costco's return policy on dehumidifiers?
Costco allows returns on most appliances within a reasonable timeframe, typically 90 days from purchase. You can return a dehumidifier to the warehouse with your receipt, or contact Costco customer service if you ordered online. The exact return window may vary, so ask at the register or check your receipt when you buy.
Does Costco deliver dehumidifiers, or do I have to pick one up?
Both options are available depending on the model and your location. Warehouse pickup is usually free for members. Home delivery is available for most models but costs vary by distance and weight—typically $30 to $100. Check the delivery cost on Costco.com before you place your order.
What size dehumidifier should I buy for my basement?
A 30-pint unit works for basements under 500 square feet. A 50-pint unit handles 500 to 1,000 square feet. A 70-pint unit is best for spaces over 1,000 square feet or very humid climates. The product tag or Costco.com listing will show the recommended square footage range for each model.
Are Costco dehumidifiers cheaper than other stores?
Prices are usually competitive with Amazon, Best Buy, and Walmart, though not always the lowest. The main benefit of buying at Costco is the return policy and the ability to see customer reviews in the warehouse before you buy. If the model in stock meets your needs, the convenience often outweighs a small price difference.
