Shopping for a **Costco dehumidifier** is a little different from shopping on Amazon. Costco doesn't keep a fixed, searchable lineup; it runs a rotating assortment where models appear, sell through and sometimes return months later at a very different price. The only model we could confirm as a standing listing on Costco.com is the **Hisense 35-Pint (HD3526)**.

Beyond that, Midea and Danby 50-pint units with built-in pumps have shown up repeatedly in member deal reports during 2026, often in specific warehouses and sometimes for only a few weeks. That's great if you catch one at a clearance price — but it means you need to know what a good unit looks like before you're standing in the aisle. Here's what we found, which models are worth buying and what to check on the box.

## Our top picks

- **Best overall (standing listing):** Hisense HD3526 — [check price on Amazon](https://www.amazon.com/s?k=Hisense%20HD3526&tag=sktiger-20)
- **Best rotating deal:** Midea 50-Pint Pump — [check price on Amazon](https://www.amazon.com/s?k=Midea%20MAD50PS1BWT-C&tag=sktiger-20)
- **Best if you catch it in stock:** Danby 50-Pint Pump — [check price on Amazon](https://www.amazon.com/s?k=Danby%20DDR050BJPWDB&tag=sktiger-20)

The **Hisense 35-Pint HD3526** is the best Costco dehumidifier you can reliably find: ENERGY STAR certified, sized for most rooms and consistently listed on Costco.com.

## 1. Hisense 35-Pint Dehumidifier (HD3526) — Best overall (standing listing)

[Check price on Amazon](https://www.amazon.com/s?k=Hisense%20HD3526&tag=sktiger-20)

**Pros**

- ENERGY STAR certified
- Consistently available on Costco.com
- Three fan speeds and 162 CFM airflow
- Auto shut-off, washable filter, slide-out bucket

**Cons**

- No built-in pump
- Room-sized rather than whole-basement capacity

**Why we picked it:** It's the one Costco dehumidifier you can count on finding, and it's a sensible, efficient machine for a large room or a mildly damp lower level. No treasure hunt required.

**Performance:** Costco's item page lists it at 35 pints a day for up to 3,000 square feet, with ENERGY STAR certification, 162 CFM of airflow, three fan speeds and an 8.9-pint bucket that shuts the unit off when full. It has a washable filter and a slide-out tank, but no pump, so you'll be emptying the bucket unless you can set up gravity drainage. For a wet basement, our [basement picks](https://www.enthusiastreview.com/best/best-dehumidifier-for-basement/) have more capacity.

| Spec | Value |
| --- | --- |
| Capacity | 35 pints/day |
| Coverage | Up to 3,000 sq ft (maker) |
| Tank | 8.9 pints |
| Airflow | 162 CFM |
| Efficiency | ENERGY STAR |
| Drainage | Bucket |

## 2. Midea 50-Pint Dehumidifier with Built-In Pump (MAD50PS1BWT-C) — Best rotating deal

[Check price on Amazon](https://www.amazon.com/s?k=Midea%20MAD50PS1BWT-C&tag=sktiger-20)

**Pros**

- Full 50-pint capacity
- Built-in pump drains up and out
- Coverage up to about 4,500 sq ft
- Same capacity class as our overall top picks

**Cons**

- Availability and price vary widely by warehouse
- Older clearance stock may carry a different suffix

**Why we picked it:** If you spot this one, it's the Costco find to grab for a basement. A 50-pint unit with a pump is exactly what most drainless basements need, and Costco's clearance pricing on it has been genuinely good at times.

**Performance:** Midea rates it at 50 pints a day for up to about 4,500 square feet, with a built-in pump that pushes water to a sink or out a window. Check the model suffix on the box: an older MAD50PS1AWT-C version has also turned up, which can signal older clearance stock. Our [50-pint guide](https://www.enthusiastreview.com/best/best-50-pint-dehumidifier/) compares it with rivals.

| Spec | Value |
| --- | --- |
| Capacity | 50 pints/day |
| Coverage | Up to about 4,500 sq ft (maker) |
| Drainage | Built-in pump |
| Type | Compressor |
| Best for | Basements without a floor drain |

## 3. Danby 50-Pint Dehumidifier with Built-In Pump (DDR050BJPWDB) — Best if you catch it in stock

[Check price on Amazon](https://www.amazon.com/s?k=Danby%20DDR050BJPWDB&tag=sktiger-20)

**Pros**

- 50-pint capacity with a built-in pump
- Has appeared at steep clearance prices
- Established appliance brand

**Cons**

- Frequently out of stock
- Danby has recall history on older models

**Why we picked it:** When it's on the shelf, it's another capable 50-pint pump unit at a club price. It's a solid alternative to the Midea if that one isn't in your warehouse.

**Performance:** This is a 50-pint compressor unit with a built-in pump for continuous drainage. Member reports showed it at a deep discount in spring 2026 before it went out of stock, so treat any price you see quoted online as stale until you check. Danby has been part of more than one CPSC recall on older models; read our [Danby guide](https://www.enthusiastreview.com/best/best-danby-dehumidifier/) before buying, especially if you're considering a used or open-box unit.

| Spec | Value |
| --- | --- |
| Capacity | 50 pints/day |
| Drainage | Built-in pump |
| Type | Compressor |
| Best for | Basements, large rooms |

## Costco dehumidifiers, by the numbers

- **1** — Dehumidifier we could confirm as a standing Costco.com listing
- **~2×** — Price spread reported on the identical Midea 50-pint SKU during 2026
- **3.4M** — Units in Midea's 2016 recall — an older generation than current stock

That middle number is the key to shopping Costco. The same Midea pump model was reported at everything from roughly $100 on in-store clearance to about $200 at regular member price — the same box, months apart.

## How we pick Costco dehumidifiers

We don't lab-test dehumidifiers. For this guide we checked Costco.com for live listings and specs, tracked member-reported warehouse sightings and price history through 2026, and cross-checked each model's capacity and features against manufacturer information and the CPSC recall database.

We clearly separate the model you can order today from those you'll have to hunt for, and we judged each on capacity, drainage and safety history rather than on any single sale price.

## What to look for in a Costco dehumidifier

- **The full model number:** Check the suffix on the box. A different letter can mean older stock or a different version.
- **Capacity for your space:** 35 pints for a large room, 50 pints for a basement. Our [size guide](https://www.enthusiastreview.com/guides/dehumidifier-size-guide/) helps you decide.
- **A pump if you need one:** If there's no floor drain near where it will sit, a built-in pump saves daily bucket trips. Compare options in our [pump guide](https://www.enthusiastreview.com/best/best-dehumidifier-with-pump/).
- **The manufacture date:** On clearance or open-box units, check the nameplate date against CPSC.gov recalls.
- **Costco's return policy:** Costco's generous returns are a real advantage for an appliance you can't try in the store. Keep the receipt.

## Why Costco's dehumidifier selection keeps changing

Warehouse clubs work on a "treasure hunt" model: limited, rotating stock designed to make you buy when you see it. For dehumidifiers, that has a few practical consequences.

- **Search won't always find it.** Costco.com reliably shows the Hisense HD3526, but the Midea and Danby pump units mostly surface through warehouse sightings and member forums.
- **Prices are promotional and regional.** Member sales, in-store clearance and regional overstock all affect the same item number.
- **Stock is a snapshot.** A unit that's gone today may reappear next season, and vice versa.

| Model | Capacity | Pump | Where you'll find it |
| --- | --- | --- | --- |
| Hisense HD3526 | 35 pints | No | Standing Costco.com listing |
| Midea MAD50PS1BWT-C | 50 pints | Yes | Rotating; warehouse and online deals |
| Danby DDR050BJPWDB | 50 pints | Yes | Rotating; often out of stock |
| Hisense HD5026TLP (TopLift) | 50 pints | Yes | Occasional warehouse sightings |

## Are Costco dehumidifiers recalled?

Not current stock, as far as we found. Midea's name is attached to a large 2016 CPSC recall — about 3.4 million 25- to 75-pint dehumidifiers built between 2003 and 2013 and sold under Midea, Frigidaire, Crosley, Kenmore and GE brands — but that's a different generation from the units now rotating through Costco. Danby has its own, separate recall history on older models. We found no CPSC dehumidifier recall for Hisense.

> **Buying used or deep clearance?:** Find the manufacture date on the nameplate and check it at CPSC.gov. It takes two minutes and applies to any brand.

## Costco vs. other retailers

If you see a strong price at Costco on a model you've already researched, buy it — but don't wait around for it to come back. Sam's Club tends to have a shorter, steadier lineup; see our [Sam's Club guide](https://www.enthusiastreview.com/best/best-sams-club-dehumidifier/). Walmart has the opposite problem, with a huge marketplace that mixes real brands with obscure imports; our [Walmart guide](https://www.enthusiastreview.com/best/best-walmart-dehumidifier/) shows how to tell them apart.

## Which Costco dehumidifier should you buy?

| Your situation | Best Costco pick | Why |
| --- | --- | --- |
| Large bedroom, family room or mildly damp lower level | Hisense HD3526 | Efficient, right-sized and easy to order online |
| Basement with no floor drain | Midea 50-Pint with pump | Full capacity plus a pump to lift water to a sink |
| Basement, Midea not in stock | Danby 50-Pint with pump | Same class and drainage; check recall history first |
| Wet basement with a floor drain | Hisense HD3526 or either 50-pint | A gravity hose makes the pump optional |

If none of these is in stock and you need a unit now, don't settle for whatever happens to be on the pallet. A right-sized, honestly rated model from another retailer will serve you better than a mismatched bargain — our [best dehumidifier roundup](https://www.enthusiastreview.com/best/best-dehumidifier/) is the place to start.

## The bottom line

The **Hisense HD3526** is the best Costco dehumidifier you can reliably buy: efficient, right-sized for most rooms and always on Costco.com. If your warehouse has the **Midea 50-Pint with pump** or the **Danby 50-Pint with pump** at a good price, either is a smart grab for a basement — just check the model suffix and, for Danby, the recall history first.

## Frequently asked questions

### Does Costco sell dehumidifiers?

Yes, but not as a fixed lineup. The Hisense 35-Pint HD3526 is a standing online listing; Midea and Danby 50-pint pump models rotate in and out of warehouses and Costco.com depending on season and region.

### What is the best dehumidifier at Costco?

For reliable availability, the Hisense HD3526: ENERGY STAR certified and rated for up to 3,000 square feet. For a basement, the Midea 50-Pint with built-in pump is the better find when it's in stock.

### Does Costco sell Danby dehumidifiers?

Sometimes. The Danby 50-pint with built-in pump (DDR050BJPWDB) has appeared at Costco during 2026, including at clearance prices, but it's frequently out of stock. Check Danby's recall history before buying, especially used or open-box.

### Why do Costco dehumidifier prices vary so much?

Costco treats dehumidifiers as rotating seasonal deals. Member sales, in-store clearance and regional overstock can put the same model at very different prices within a few months.

### Should I buy a dehumidifier at Costco or Amazon?

Buy at Costco if the specific model you want is in stock at a good price — the return policy is a plus. Amazon offers steadier availability and easier side-by-side comparison.
