A TOSOT dehumidifier is Gree Electric's answer to shoppers who want ENERGY STAR efficiency without a name-brand price. Gree is one of the world's largest air-conditioning manufacturers, and TOSOT is its consumer label, best known online for undercutting Frigidaire and hOmeLabs while still offering features like washable filters and built-in pumps.

The current GDN series comes in three sizes: a bucket-only 30-pint for single rooms and two pump-equipped models for basements and open spaces. Owner ratings across the lineup are strong for the budget tier, averaging around 4.6 stars across several hundred reviews. One quirk confuses many buyers, though: TOSOT's own storefront lists a different, discontinued line, which makes it look as though the brand has left the category. It hasn't.

We compared the lineup on manufacturer specs, ENERGY STAR status, owner-review patterns and seller details. We don't lab-test dehumidifiers ourselves.

## Our top picks

- **Best overall:** TOSOT GDN50BA — [check price on Amazon](https://www.amazon.com/s?k=TOSOT%20GDN50BA-A3EBA2E&tag=sktiger-20)
- **Best for single rooms:** TOSOT GDN30AZ — [check price on Amazon](https://www.amazon.com/s?k=TOSOT%20GDN30AZ-A3EBA2C&tag=sktiger-20)
- **Best for large basements:** TOSOT GDN70BA — [check price on Amazon](https://www.amazon.com/s?k=TOSOT%20GDN70BA-A3EBA2D&tag=sktiger-20)

The **TOSOT GDN50BA-A3EBA2E** is the one most homes should buy: the right size for a typical basement or open living area, with a built-in pump so you never empty a bucket.

## 1. TOSOT 50-Pint Dehumidifier with Pump (GDN50BA-A3EBA2E) — Best overall

[Check price on Amazon](https://www.amazon.com/s?k=TOSOT%20GDN50BA-A3EBA2E&tag=sktiger-20)

**Pros**

- Built-in pump drains through a garden-hose fitting
- ENERGY STAR certified
- Washable air filter
- Rated for roughly 3,000 sq ft

**Cons**

- Listings mix old and new pint ratings
- Buy from the right seller to avoid reseller stock

**Why we picked it:** This is the size most basements and open living areas actually need, and the built-in pump is what sets it apart from the cheaper 30-pint. Run a hose to a sink or out a window and it can work for weeks without attention.

**Performance:** TOSOT lists it at 50 pints a day under the current DOE standard (70 under the older rating that still appears on some listings), covering about 3,000 square feet. The pump pushes water uphill, so you aren't limited to a floor drain. Owners frequently mention the value for a pump model in this price tier; if you need more capacity, the GDN70 is the step up.

| Spec | Value |
| --- | --- |
| Capacity | 50 pints/day (DOE 2019, per TOSOT) |
| Drainage | Built-in pump, garden-hose fitting |
| Coverage | About 3,000 sq ft |
| Efficiency | ENERGY STAR |
| Best for | Basements, open living areas |

## 2. TOSOT 30-Pint Dehumidifier (GDN30AZ-A3EBA2C) — Best for single rooms

[Check price on Amazon](https://www.amazon.com/s?k=TOSOT%20GDN30AZ-A3EBA2C&tag=sktiger-20)

**Pros**

- Quiet, at a listed 48 dB on high
- ENERGY STAR certified
- Sized for rooms up to about 1,500 sq ft
- Washable filter

**Cons**

- No pump — bucket only
- Capacity listed on the older rating scale

**Why we picked it:** For one damp room — a bedroom, home office or single-car garage — this is the simplest TOSOT to live with. Its listed 48 dB on high puts it among the quieter units in its class.

**Performance:** It's rated at 30 pints a day on the pre-2019 scale, so expect less under today's stricter test. There's no pump or continuous-drain option, so you'll empty the bucket as it fills. See how it stacks up against other small units in our [best 30-pint dehumidifier](https://www.enthusiastreview.com/best/best-30-pint-dehumidifier/) guide.

| Spec | Value |
| --- | --- |
| Capacity | 30 pints/day (pre-2019 scale) |
| Drainage | Bucket only |
| Noise | 48 dB on high (listed) |
| Coverage | About 1,500 sq ft |
| Best for | Bedroom, office, single-car garage |

## 3. TOSOT 70-Pint Dehumidifier with Pump (GDN70BA-A3EBA2D) — Best for large basements

[Check price on Amazon](https://www.amazon.com/s?k=TOSOT%20GDN70BA-A3EBA2D&tag=sktiger-20)

**Pros**

- Highest capacity in the lineup
- Built-in pump for continuous drainage
- Adjustable humidistat from 35% to 80%
- Rated for about 4,500 sq ft

**Cons**

- Slightly louder, at a listed 52 dB
- More than a mid-size basement needs

**Why we picked it:** When the 50-pint's coverage falls short — a big finished basement or a large, damp lower level — the GDN70 brings the same pump design with more capacity.

**Performance:** TOSOT lists 70 pints a day and coverage up to about 4,500 square feet, with an LED display and a humidistat you can set between 35% and 80%. It's a few decibels louder than the smaller models, which is typical for the size. Compare it with wetter-climate options in our [best dehumidifier for basement](https://www.enthusiastreview.com/best/best-dehumidifier-for-basement/) guide.

| Spec | Value |
| --- | --- |
| Capacity | 70 pints/day (as listed) |
| Drainage | Built-in pump |
| Humidistat | 35–80% |
| Noise | 52 dB on high (listed) |
| Coverage | About 4,500 sq ft |
| Best for | Large or damp basements |

## TOSOT dehumidifiers, by the numbers

- **4.6★** — Average owner rating across the GDN lineup
- **2 of 3** — Models with a built-in pump
- **48 dB** — Listed noise of the 30-pint on high

TOSOT also runs frequent online discounts on the GDN series, so if you're not in a hurry, it's worth watching the price for a few weeks.

## How we pick TOSOT dehumidifiers

We compared each GDN model on its manufacturer specs (capacity, rated coverage, noise, humidistat range and drainage) and confirmed ENERGY STAR certification. Because TOSOT listings mix the pre-2019 and current DOE rating scales, we noted which scale each figure uses rather than comparing them directly.

We also read owner reviews for recurring problems, checked the CPSC recall database and looked into the seller situation that confuses so many TOSOT shoppers. We don't run hands-on tests; this guide relies on published data and owner experience.

## What to look for in a TOSOT dehumidifier

- **Capacity matched to square footage:** About 1,500 sq ft for the 30-pint, 3,000 for the 50 and 4,500 for the 70. Our [dehumidifier size guide](https://www.enthusiastreview.com/guides/dehumidifier-size-guide/) adjusts for dampness.
- **Which rating scale you're reading:** Some listings show old pre-2019 numbers. Compare models on the current DOE 2019 figure wherever it's given.
- **Pump or bucket:** Only the 50- and 70-pint models pump water out. The 30-pint needs manual emptying.
- **The right seller:** Buy listings shipped and sold by TOSOT itself. Older GDN stock also circulates through third-party resellers.
- **Price history:** TOSOT discounts often. A short wait can save a meaningful amount.

## TOSOT models at a glance

| Model | Best for | Capacity | Coverage | Pump |
| --- | --- | --- | --- | --- |
| GDN30AZ-A3EBA2C | Single room | 30 pints (pre-2019 scale) | ~1,500 sq ft | No |
| GDN50BA-A3EBA2E | Most homes | 50 pints (DOE 2019) | ~3,000 sq ft | Yes |
| GDN70BA-A3EBA2D | Large basements | 70 pints (as listed) | ~4,500 sq ft | Yes |

If price is your main concern for a single room, a budget unit from hOmeLabs can undercut the TOSOT 30-pint, though TOSOT's is quieter. Once you want a pump, TOSOT's lineup is the more complete value.

## Is TOSOT discontinued? Why the brand's website says so

Search for TOSOT directly and you may land on the brand's own storefront, where the dehumidifiers shown (models TST-NDHM-20WHT and TST-NDHM-50WHT-P) are marked discontinued with no way to buy. That's a separate, older line. The GDN-series units in this guide remain on sale, shipped and sold by TOSOT through Amazon.

### Who makes TOSOT dehumidifiers?

TOSOT is the consumer brand of Gree Electric, a giant in air conditioning that has also built dehumidifiers sold under other companies' names over the years. That's worth knowing for two reasons: TOSOT units share engineering with a large global production line, and older Gree-built units from other brands were part of a major fire-hazard recall first announced in 2013 and reannounced in later years. If you own any older Gree-made dehumidifier, check its model number at CPSC.gov.

> **Before you check out:** Confirm the listing says it ships from and is sold by TOSOT, and that the model number matches exactly. That's your best protection against old or gray-market stock.

## TOSOT dehumidifier manual and setup tips

If you've misplaced the printed manual, product listings for the GDN series often include a downloadable user guide, and TOSOT's customer service can supply one for your exact model number. The key setup steps are the same as for most compressor units.

1. **Let the unit stand upright** for several hours after delivery before plugging it in.
2. **Leave clearance** of about a foot around the intake and outlet. See [where to place a dehumidifier](https://www.enthusiastreview.com/guides/where-to-place-a-dehumidifier/).
3. **For pump models,** attach the drain hose to the pump outlet and run it to a sink, drain or window without kinks.
4. **Set the humidistat to 45–50%** rather than leaving it on continuous.
5. **Rinse the washable filter** every two to four weeks in heavy use. Our [maintenance guide](https://www.enthusiastreview.com/guides/dehumidifier-maintenance/) covers the rest.

## The bottom line

The **TOSOT GDN50BA-A3EBA2E** is the best TOSOT dehumidifier for most homes, pairing the right capacity for a typical basement with a built-in pump. Go smaller with the quiet **GDN30AZ-A3EBA2C** for one room, or bigger with the **GDN70BA-A3EBA2D** for a large basement. All three are ENERGY STAR certified and well rated by owners — just buy from TOSOT's own Amazon listing and ignore the discontinued models on its storefront.

## Frequently asked questions

### What is the best TOSOT dehumidifier?

The GDN50BA-A3EBA2E for most homes. It's listed at 50 pints a day under the current DOE standard, covers about 3,000 square feet and has a built-in pump. The GDN30AZ-A3EBA2C suits a single room, and the GDN70BA-A3EBA2D suits a large basement.

### Is TOSOT a good dehumidifier brand?

For the budget tier, yes. The GDN series is ENERGY STAR certified, has washable filters and averages about 4.6 stars from several hundred owners. TOSOT is a Gree Electric brand, so build quality follows Gree's broader appliance line.

### Are TOSOT dehumidifiers discontinued?

The GDN series isn't. TOSOT's own storefront lists an older line (TST-NDHM-20WHT and TST-NDHM-50WHT-P) as discontinued, but the GDN models are still sold and shipped by TOSOT through Amazon.

### Does the TOSOT dehumidifier have a pump?

The 50- and 70-pint models do; both can push water uphill through a garden-hose fitting. The 30-pint GDN30AZ-A3EBA2C is bucket-only.

### How does TOSOT compare to hOmeLabs?

They compete in the same budget tier. A small hOmeLabs unit can cost less than the TOSOT 30-pint for similar coverage, but the TOSOT is quieter at a listed 48 dB. Once you want a pump, TOSOT's 50- and 70-pint models are usually the better value.

### Where can I find a TOSOT dehumidifier manual?

Check the product listing for a downloadable user guide, or contact TOSOT customer service with your full model number. Basic setup is simple: let it stand upright before first use, leave clearance around it, set the humidistat to 45–50% and rinse the filter regularly.

### How big a space does a TOSOT dehumidifier cover?

About 1,500 square feet for the 30-pint, roughly 3,000 for the 50-pint and up to about 4,500 for the 70-pint. A very damp space may need the next size up.
