Quick Answer: The best TOSOT dehumidifier in 2026 is the GDN50BA-A3EBA2E — 50 pints per day (70 pints under the older pre-2019 DOE scale), a built-in pump for continuous drain, and listed around $170-220. The GDN30AZ-A3EBA2C (about $150-200) covers a single room up to 1,500 sq ft without a pump, and the GDN70BA-A3EBA2D (about $190-240) scales up to about 4,500 sq ft. All three carry a 4.6-star average across roughly 400 Amazon reviews, but TOSOT’s own direct-to-consumer website currently lists a different, discontinued product line — worth knowing before you assume the brand has exited the category.
TOSOT is a Gree Electric sub-brand best known on Amazon for undercutting name brands like Frigidaire and hOmeLabs on price while still hitting Energy Star efficiency numbers. Below we compare the three active pint tiers, flag the pump-vs-no-pump split, and explain the discontinued-storefront wrinkle that trips up some buyers searching for the brand directly.

TOSOT dehumidifiers by the numbers
- 4.6 stars across roughly 400 reviews on Amazon for the TOSOT lineup — a strong rating for the budget tier, on par with or ahead of several higher-priced competitors on this site.
- 48 dB is the GDN30AZ-A3EBA2C’s quoted noise level on its high fan setting, quiet enough for a bedroom or home office and one of the reasons it’s a repeat pick across our capacity-tier guides.
- 52 dB on the GDN70BA-A3EBA2D — a few decibels louder than the 30-pint model, the tradeoff for roughly double the moisture-removal capacity.
- 20-23% off is the discount range TOSOT’s Amazon listings ran at in a recent sitewide dehumidifier sale, per a Daily Beast deals roundup — a pattern worth watching for if you’re not in a rush to buy at full price.
- Only 2 of 3 models pump. The 50- and 70-pint units both include a built-in internal pump for continuous garden-hose drainage; the 30-pint model is bucket-only.
- 24 to 48 hours is how fast mold can begin growing on a damp surface, per the EPA — the reason a pump-equipped model that never needs manual emptying is worth the upcharge in a basement nobody checks daily.
1. TOSOT GDN50BA-A3EBA2E — Best Overall TOSOT
TOSOT GDN50BA-A3EBA2E (50 Pint, With Pump)
- 50 pints per day under the current DOE-2019 standard (70 pints under the older pre-2019 rating still printed on some listings), covering roughly 3,000 sq ft.
- Built-in internal pump pushes water uphill through a standard garden-hose fitting — no gravity drain or manual bucket-emptying required.
- Energy Star certified with a washable air filter, the same spec tier as the rest of the GDN lineup.
- 4.6-star average rating across roughly 400 Amazon reviews for the TOSOT dehumidifier line.
The GDN50BA-A3EBA2E is the size most basements and open living areas actually need, and the built-in pump is what pushes it ahead of the cheaper 30-pint model for anywhere you don’t want to check a bucket. Get your dehumidifier running in two days — try Amazon Prime free for 30 days.
If 3,000 sq ft is more capacity than your space needs, drop down to the 30-pint model below; if you’re covering a full basement, the 70-pint steps up further.
2. TOSOT GDN30AZ-A3EBA2C — Best for a Single Room
TOSOT GDN30AZ-A3EBA2C (30 Pint)
- 30 pints per day on the pre-2019 DOE scale, sized for a bedroom, home office, or single-car garage up to about 1,500 sq ft.
- 48 dB on its high fan setting — one of the quieter options in this capacity tier.
- No built-in pump; drains to an included bucket only, which needs to be emptied manually as it fills.
- Energy Star certified, same washable-filter design as the pump-equipped models.
This is the pick for a single damp room where continuous drainage isn’t worth the extra cost — see how it stacks up against the rest of its capacity class in our best 30-pint dehumidifier guide, where it’s the quietest of four genuine picks.
3. TOSOT GDN70BA-A3EBA2D — Best for Basements
TOSOT GDN70BA-A3EBA2D (70 Pint, With Pump)
- 70 pints per day, rated for larger basements and finished spaces up to about 4,500 sq ft.
- Built-in internal pump, same continuous-drain design as the 50-pint model, scaled up for a bigger moisture load.
- 52 dB on high — a few decibels above the smaller models, typical for this capacity class.
- LED display with adjustable humidistat set point between 35-80% relative humidity.
Reach for the 70-pint model when the 50-pint’s ~3,000 sq ft rating falls short of your actual basement or living space, and compare it against the wetter-climate picks in our best dehumidifier for basement guide before committing.
Why TOSOT’s own website says “discontinued”
Search for TOSOT directly and you’ll likely land on tosotdirect.com, the brand’s official storefront — where the listed dehumidifiers (model numbers TST-NDHM-20WHT and TST-NDHM-50WHT-P) are both marked discontinued with no purchase option. That’s a different model line from the GDN-series units in this guide, which remain in active production and are sold and shipped directly by TOSOT through Amazon, carrying the same 4.6-star rating and roughly 400 reviews cited above. In practice this means: ignore tosotdirect.com if you’re shopping for a TOSOT dehumidifier right now, and confirm any Amazon listing shows “Ships from and sold by TOSOT” rather than an unrelated third-party seller before buying, since old GDN-series stock does circulate through resellers.
How to choose a TOSOT dehumidifier
- Match capacity to square footage, not price alone. The 30-pint covers ~1,500 sq ft, the 50-pint ~3,000 sq ft, and the 70-pint ~4,500 sq ft — buying more capacity than the room needs just adds cost and noise.
- Decide if you need the pump. Only the 50- and 70-pint models drain continuously through a garden-hose fitting; the 30-pint is bucket-only and needs manual emptying.
- Buy from TOSOT directly on Amazon, not tosotdirect.com. The brand’s own site currently shows a discontinued, unrelated model line — the active GDN-series units are on Amazon.
- Compare against hOmeLabs if price is the deciding factor. hOmeLabs undercuts TOSOT’s 30-pint model by about $35-60 for the same coverage, though TOSOT’s pump-equipped tiers are the more complete lineup.
- Watch for the frequent 20%+ sales. TOSOT’s Amazon listings discount regularly; if you’re not in a rush, a lower price often shows up within a few weeks.
The bottom line
The TOSOT GDN50BA-A3EBA2E is the best TOSOT dehumidifier for most homes — 50 pints per day, a built-in pump for continuous drain, and around $170-220. Go smaller with the GDN30AZ-A3EBA2C (about $150-200) for a single room, or bigger with the GDN70BA-A3EBA2D (about $190-240) for a full basement. All three are Energy Star certified, hold a 4.6-star average, and are sold directly by TOSOT on Amazon — just skip tosotdirect.com, which currently lists a separate, discontinued line.
