Quick answer
If you want a Hisense for a damp basement or a large room, buy the Hisense 50-Pint Energy Star Portable Dehumidifier, rated 4.4 stars across 67 Amazon ratings; if the water has to go up to a sink or out a window, choose the Hisense 50-Pint Lift-Up Portable Dehumidifier with Built-In Pump instead. Both remove up to 50 pints a day per their listings, but Hisense does not state the temperature and humidity behind that figure, so treat the 4,500 sq ft coverage claim as a ceiling. This comparison is built from the listings and buyer ratings, not hands-on use.
Buyer's Guide
What to know before you buy.
How This Hisense Review Was Put Together
No Hisense unit was run for this page. The comparison is built from each model's Amazon listing as read on 12 October 2026, the specs Hisense states on those listings, ENERGY STAR's sizing guidance and the buyer ratings Amazon shows on each card. Where a listing leaves a number out, such as the test conditions behind its pint figure, the pump's lift height or a noise level, this page says so rather than filling the gap. Hisense currently sells dehumidifiers on Amazon at 25, 35 and 50 pints, including a lift-up model with a built-in pump in white and in black. Most of those listings are new and have short buyer records, which is a reason to keep the receipt and register the warranty, not a reason to avoid them.
Reading the Pint Rating and the Coverage Claim
A dehumidifier's pints-per-day figure depends on the air it was measured in. Since 2019 the US Department of Energy test for portable dehumidifiers has used 65°F and 60% relative humidity, cooler than the older 80°F test, so the same machine now carries a smaller number. Hisense's listings give 25, 35 and 50 pints without stating the conditions. Coverage claims are looser still, since 4,500 sq ft for a 50-pint unit assumes a moderately damp space. ENERGY STAR's sizing charts depend on the size of the space and how damp it starts, and its advice is that it is better to oversize than undersize. For a basement that smells musty or shows wet spots, choose the 50-pint even if the floor area looks small.
Pump or Gravity Drain
Every compressor dehumidifier collects water in a bucket, and an 18-pint bucket on a 50-pint machine can fill more than once a day in a damp summer basement. A hose ends that chore. Gravity draining, which the Hisense 50-Pint Energy Star model supports through a standard garden hose, needs a floor drain or sump lower than the outlet, with the hose sloping down all the way and no loops. A built-in pump, as on the Hisense 50-Pint Lift-Up model, pushes water up to a laundry sink or out a window instead. Pumps add a part that can clog, so clean the hose and outlet each season. If a drain hose pulls free, the floor gets the water, so clip it in place and check it after you move the unit.
Cold Basements and the 38°F Rating
Basements run cool, and compressor dehumidifiers slow down as the air cools, because the coil has to stay colder than the room's dew point to condense water. Below about 65°F, frost can start to form on the coil and the unit pauses to defrost. Several of Hisense's newer listings state operation down to 38°F. That means the machine is designed to keep working and defrosting in that range, not that it removes 35 or 50 pints there. Expect noticeably less water per day in a 55°F basement than the label suggests. If your space sits below about 40°F for long spells, such as an unheated garage or a crawl space in winter, a desiccant dehumidifier or a crawl space unit built for those conditions is the better tool.
Humidity Targets and Filter Care
Set the humidity target, not just the fan. EPA advises keeping indoor humidity below 60 percent, ideally between 30 and 50 percent, and ENERGY STAR says the optimum for a building is generally considered to be between 30% and 50%, with anything higher able to promote mold growth. A setting around 45 to 50% keeps a basement out of the mold range without running the compressor all day. Check the room with a separate hygrometer at first, because a built-in sensor sits at the intake and can read differently from the far corner. Wash the filter when the alert comes on, or every few weeks in heavy use, and let it dry before refitting. A dusty filter starves the coil of air, and the unit works harder for less water.
Who Should Not Buy a Hisense Dehumidifier
A portable Hisense is the wrong machine for a flooded basement. After a flood or a burst pipe, the job is drying walls, floors and cavities fast, and EPA advises drying water-damaged areas and items within 24 to 48 hours to prevent mold growth. On its own, a household unit will not do that; restoration crews use commercial dehumidifiers and air movers sized to the job. A Hisense is also not built for crawl spaces, which need a unit made to sit in a sealed crawl space and drain itself, or for garages near freezing. If you want app control, none of the listings compared here mentions Wi-Fi, so check before you buy. Where the damp comes from a leak, fix the leak first, since a dehumidifier treats the air rather than the source.
