Hisense 50-Pint Dehumidifier Review: A Pump Unit Rated to 38°F

The Hisense 50-Pint Lift-Up Dehumidifier with Built-In Pump (ALDH50KP26) is a fair pick for a cool basement that needs a pump, and a hard one to love at full price. ENERGY STAR certifies it at 49.89 pints a day on the current DOE test (65°F and 60% relative humidity) with an efficiency of 2.01 liters per kWh, which ties the Midea Cube 50 and Frigidaire's Wi-Fi 50 on paper. Two things set it apart. Its manual rates it to run down to 38°F, three degrees below the 41°F floor most portables stop at. And the bucket lifts straight out of the top by a handle, so you never kneel on a damp floor to slide a tank out.

The catches are documentation and track record. This model went on the market in January 2026, so nobody has run one for years yet, and the Hisense dehumidifiers that do have a history (older 50-pints sold through Costco and Lowe's) collect complaints about leaks and early refrigerant loss. Hisense's manual for this unit has no warranty section and no pump lift rating, and its manual documents no garden-hose gravity drain at all: you empty the bucket or you run the pump.

We'd buy it when you need a new, Amazon-sold pump model for a basement that dips into the high 30s. Otherwise the cheaper Cube or Frigidaire does the same job with a gravity hose.

Why we'd consider it

• A current-test 50: ENERGY STAR lists 49.89 pints a day at 65°F and 60% RH, the condition DOE has used for portables since June 2019, with an IEF of 2.01 L/kWh. That is the same efficiency as the Midea Cube 50 and Frigidaire FHDD5034Y1.
• A lower floor: the manual gives an operating range of 38°F to 90°F. The Cube and the Frigidaire stop at 41°F.
• Top-lift bucket: the 18-pint tank comes out of the top by its handle, per the Amazon listing. No crouching, no lifting the whole machine off its bucket the way you do with a Cube.
• Pump in the box: a built-in pump and drain hose for a basement with no floor drain below the unit.
• Light and short: Amazon lists it at 19.0 inches tall and 20.2 pounds, with four casters.

What holds it back

• No gravity drain documented: the manual covers the bucket and the pump only. If the pump quits, you're back to a bucket.
• No published pump lift: the manual says you can pump to a floor drain or out a window, but gives no height or length limit.
• No written warranty we could find: the manual has no warranty section and the Amazon listing doesn't state one. Hisense's own page for a different 50-pint pump model promises two years parts and labor.
• No noise rating: we couldn't find a Hisense decibel figure for this model in its manual or listing.
• Small bucket: 18 pints fills in under nine hours at the rated pace, so the pump is doing real work.
• Brand history: older Hisense dehumidifiers have a record of leaks out the bottom and units that lose refrigerant within a few seasons.

Which Hisense you are looking at

Amazon sells three current Hisense 50-pint units with near-identical titles, and only one of them is the compact lift-up machine reviewed here. From ENERGY STAR's records and the Amazon listings:

The black ADH50KP26 listing also calls itself Lift-Up, but its ENERGY STAR record lists the same compressor options and the same 4.8-ounce refrigerant charge as the ADH50K26, while the ALDH50KP26 carries 4.2 ounces, and Amazon lists the black unit at the taller size. We read that as a different machine. The manual we quote below is the ALDH50KP26's, so it doesn't automatically apply to the ADH units. Check for ALDH50KP26 in the listing details before you buy if the top-lift bucket is the reason you want it.

You'll also see older Hisense names in owner threads and on store shelves: the DH5023KP, DH5024KP1G and DH5026KP1G, and an AHD5024K1W that Amazon lists only through a third-party seller and that isn't in the current ENERGY STAR list. None of those is this unit.

Rated capacity, and what 38°F buys you

Start with the number that matters. At 49.89 pints a day on the 65°F test, this is a full-size 50 by today's rules, not an old 80°F rating dressed up. ENERGY STAR's rough conversion puts an old-test 50 near 30 pints on the current test, which is why we treat units still quoting 80°F figures, like hOmeLabs' 50-pint line, as smaller machines. The Hisense doesn't need that asterisk.

Running cost is easy to bound. 49.89 pints is about 23.6 liters; at 2.01 liters per kWh, a full day at the rated pace uses roughly 11.7 kWh. ENERGY STAR puts its annual use at 526 kWh. Multiply either figure by your own electric rate; what you pay depends on how long the compressor runs before your basement reaches its set point.

Treat the 38°F floor as a cutoff. The manual says water freezes inside the unit at 38°F or less, so that's where it quits. Cold air holds little water, and any compressor dehumidifier pulls far fewer pints at 45°F than at 65°F. We couldn't find a Hisense capacity figure below the test point, so we can't tell you how many pints it makes in a 40°F space. What the lower floor does buy you is a unit that keeps cycling through a cold snap in an unheated basement where a 41°F machine would sit idle. For a true crawl space that drops toward freezing, the AlorAir Sentinel HD55S is rated to 33.8°F and built for the job.

Expect heat too. The manual says the room may warm by about 6°F depending on conditions, because a dehumidifier gives back the electricity it uses and the heat from the water it condenses. In a cold basement, that helps. In a finished room in August, plan for it.

The lift-up bucket and the pump

The bucket is the design's best idea and its smallest number. Lifting an 18-pint tank out of the top by a handle beats pulling a drawer from near the floor. But 18 pints at the rated 49.89 pints a day is a full bucket about every 8.7 hours, close to three trips a day in a soggy July. Frigidaire's FHDD5034Y1 holds 2.7 gallons (21.6 pints), and Midea's listing claims about 4.2 gallons for the Cube 50. With this Hisense, the pump is the plan, and the bucket is the backup.

Here's how the pump works, per the manual. You seat the bucket, then insert the drain hose into the drain outlet and make sure it's secure; to remove it, you hold the dark gray ring and pull the hose straight out. While the hose is connected, the bucket can't come out, and the manual warns that forcing it can damage the connector. A kinked or pinched hose stops the unit with an EB code, and so can a clogged water filter. After every 30 hours of pump run time, a Water light reminds you to clean that filter, which means pulling the drain cover, draining the leftover water and washing the filter. The air filter gets its own reminder after 360 hours of fan time. Rinse the bucket weekly, as the manual asks, even when you run the pump, so slime doesn't build up.

Two gaps in the paperwork matter. First, there's no pump lift figure. Hisense's manual for its older DH5024 pump models allows a 16-foot hose with less than 16 feet of height, but that's a different machine, and we wouldn't assume the same for this one. If your sink or window is more than a few feet up, ask the seller before you buy. Second, the older Hisense 50s took a garden hose for gravity draining; this manual describes no gravity drain. That means a dead pump turns the machine into a bucket unit until it's fixed. If you have a floor drain or sump right below where the dehumidifier will sit, a gravity-drained Cube or Frigidaire is the simpler setup.

Placement is simple. The manual wants 12 to 18 inches of open space around the unit, a level floor strong enough for a full bucket, a grounded 3-prong outlet on a 115-volt circuit protected by a 15-amp time-delay fuse or breaker, and no adapter or extension cord. It also uses R32, a flammable refrigerant, so follow the manual's placement warnings and keep it away from ignition sources.

Where it fits

The good fit is an unfinished or lightly finished basement with no drain at floor level, a utility sink or window to pump to, and winter lows that sit in the high 30s. Set it in Manual mode at 45-50%; EPA's guidance is to keep indoor humidity below 60%, ideally 30-50%. The manual says humidity can only be set by hand in Manual Set mode, and Auto Dry picks 50% for you.

Skip it if:

• You have a floor drain or sump below the unit: a gravity hose is the most reliable drain there is. The Midea Cube 50 and the Frigidaire FHDD5034Y1 certify about the same capacity, take a hose, and cost less.
• The space drops toward freezing: a vented crawl space or a garage in a cold state needs a unit built for it. The AlorAir Sentinel HD55S is rated to 33.8°F.
• It goes in a living room or bedroom: we couldn't find a Hisense noise rating for it, and the manual says the fan may turn on periodically to read the humidity even when the compressor is off. That's fine in a basement and irritating beside a TV.
• You want the warranty in writing first: we couldn't find one for this model; see the track record section below.

Track record and warranty

Everything in this section is brand history. None of the owner reports we could find names the ALDH50KP26, which has only been on sale since January 2026. Most concern older Hisense 50-pints bought at Costco or Lowe's, and repair threads attract the unhappy, so treat the balance as a warning sign, not a failure rate.

Leaks out the bottom are the most specific complaint. Several buyers of new Hisense units from Costco found water on the floor instead of in the bucket, and the fix that worked for some was tightening the cap on the rear garden-hose connector. This lift-up model has no garden-hose connector described in its manual, so that exact leak path may not exist here, but check the floor under a new unit for the first few days anyway.

Early refrigerant loss is the other theme, and it isn't unique to Hisense. A one-year-old DH5023KP started icing within seconds of start-up even after its owner cleaned the coils; another Hisense was low on refrigerant at three years; a Costco buyer's Hisense quit after one season. A unit that runs and blows air but collects no water, or that frosts over in a warm room, has often lost refrigerant. The manual leaves repairs to qualified service personnel, and on a flammable-refrigerant machine that's right, which is why the warranty question below matters.

There are long runs too. One owner ran a Hisense for years and bought another when it finally went, and another says it takes load off the air conditioning. Owners also notice the heat and the periodic fan: one basement went from cool to 77°F with a new Hisense running, which fits the manual's 6°F warning.

The warranty is the weak point. The ALDH50KP26 manual we found has no warranty section, and the Amazon listing doesn't state a term. Hisense's own product page for its DH5026KP1G 50-pint pump model says Hisense provides two years on parts and labor, which would beat the one year Midea and Frigidaire give. We can't confirm that the same term covers this model, so we don't score it as if it does. Before you buy, ask Hisense support (the number on the manual is 1-877-465-3566) or the seller what the ALDH50KP26 carries, and keep the order record. If it's two years, the reliability case improves meaningfully.

Against the other 50s

Every capacity below is an ENERGY STAR figure at the 65°F DOE test.

Midea Cube 50: the same certified capacity and efficiency, a much bigger bucket and a gravity hose in the box, and it listed for less when we checked. Its pump version had only used units on Amazon when we last looked, and its built-in humidity reading can stick low on a new unit, so check it against a hygrometer in week one. With a floor drain, we'd buy the Cube.

Frigidaire FHDD5034Y1: an equal on capacity and efficiency, published noise figures (47-51 dBA) and a 2.7-gallon bucket, but no pump and a 41°F floor. It also listed for less than the Hisense when we checked.

Honeywell TPFIT50PWK: the other current-test 50 with a pump, with a published lift. Its four-year sealed-system term looks better than it is now that its licensee says it's out of business, and the Amazon offer came from a third-party seller at a higher price when we checked. Between the two pump units, we'd take the Hisense.

AlorAir Sentinel HD55S: costs far more and drains by gravity only, but it's the machine for a crawl space that gets close to freezing. If your space spends winter around 35°F, skip both portables.

Who should buy it

Buy the ALDH50KP26 if your basement has no drain below the unit, gets into the high 30s in winter, and you want a pump without buying a separate condensate pump and wiring its overflow switch. It's a real current-test 50 with a sensible top-lift bucket and, alongside LG's DT501, the lowest operating floor among the 50-pint portables we've reviewed. Confirm the warranty before you order, clean the pump's water filter when the light comes on, and keep an eye on the floor under it for the first week. If you have a drain or sump below the unit, save the money and buy the Midea Cube 50.
