The Best Basement Dehumidifiers of 2026

Capacity and coverage

Basements are cool, and dehumidifiers remove less water at lower temperatures. A 50-pint unit (under the current DOE test) is the usual choice for large or damp basements. Smaller 20- to 35-pint models fit only small or mildly damp rooms. If in doubt, size up.

Draining

This matters more than tank size. If you have a floor drain or sump, a gravity hose is enough. If not, a built-in pump can send water up to a sink or out a window. Without either, you will be carrying a heavy bucket up the stairs.

Low-temperature operation

Look for auto-defrost, so the coils don't ice up in a cool basement, and auto-restart so the unit resumes after a power cut. Compressor models work well in most basements; if the space regularly sits near freezing, a desiccant style may be worth considering.

Noise

For an unfinished basement, noise is minor. For a finished room, or one under a bedroom, check noise ratings closely. Several of the strongest basement performers are loud.

Energy use

A dehumidifier may run for long stretches. ENERGY STAR certification and a higher IEF (liters per kilowatt-hour) mean lower running costs. Weight also matters: these units are heavy, and a full bucket more so.

Energy use is the clearest difference between these picks. The Midea Cube 50 pump model is ENERGY STAR certified (the -A variant), at 49.67 pints a day, an IEF of 2.01 L/kWh and about 515 kWh a year. That meets the current minimum but is not in the Most Efficient tier. The Midea Cube 20 is also certified, at the minimum for its class. Reviewed measured the non-pump Cube 50 as the lowest power draw among the 50-pint units it tested. We found no ENERGY STAR information for the Dreo or Ivation.

For homes with children or pets, the Dreo has a child lock, tilt shutoff and thermal overload protection. A 2016 recall involved older units made by GD Midea; it did not cover the current Cube models.

Keep humidity around 30 to 50 percent, and empty and clean tanks regularly. Standing water can grow mold and mildew.

Eva-Dry EDV-4000H: A small desiccant model that works in near-freezing spaces and is quiet, but it covers only about 444 sq ft, and Amazon showed it backordered until mid-November.

Hisense DH7021K1W: Reviewed's Best Value pick. We could not find a current new unit with a clear listing, so we left it out.

GoveeLife H7151: Out of stock on Amazon, and Tom's Guide measured more than 70 dB on high.

Frigidaire GHDD5035W1 and FHDP6033W1: We could not find a reliable current retail listing for either, and sources disagree on features of the latter.

Honeywell TPFIT50PWK: Costs more than our top pick, with less independent testing behind it.

Hisense ALDH50KP26 and HomeLabs HME020030N: Left out because of unclear pump specs and a very small tank with no hose, respectively.

BlueDri BD-130: A heavy commercial restoration unit, not a routine basement dehumidifier.

What size dehumidifier do I need for a basement?

For a large or damp basement, choose a 50-pint (DOE) model rated for around 4,500 sq ft. A 20-pint unit works only for small, mildly damp spaces up to about 1,500 sq ft.

Do I need a built-in pump?

Only if you lack a floor drain or sump nearby. A pump lifts water to a sink or window. If you can run a gravity hose to a drain, a non-pump model is fine.

What humidity level should I aim for?

Keep indoor humidity roughly between 30 and 50 percent. Higher levels encourage mold and musty smells.

Will a dehumidifier work in a cold basement?

Compressor units work in most basements, and models with auto-defrost handle cooler air better. Their output drops as temperatures fall. In spaces near freezing, a desiccant model is more suitable.

Are these dehumidifiers loud?

The large 50-pint units generally are. RTINGS rates the top pick's noise poor, so it is better suited to unfinished basements. For a finished room, the Dreo's sleep mode or the small Midea Cube 20 are quieter choices.

Can I leave a dehumidifier running all the time?

Yes, if it drains continuously and has a humidistat that shuts it off at your target level. Use a hose or pump so a full tank doesn't stop it.

For most basements, the Midea Cube 50 with built-in pump is the one to buy: big capacity, easy draining and a sensible price, with noise as the trade-off. Choose the non-pump Midea if you have a floor drain and want the fastest tested pull-down, the Dreo if kids and pets share the space, the Ivation as a pump alternative for an unfinished basement, and the small Midea Cube 20 only for a modest, mildly damp room. Whatever you pick, size it to the space and set up continuous drainage if you can.
