If your basement smells like a wet towel, or your windows drip every winter morning, you don’t need more air freshener. You need to pull water out of the air. A good dehumidifier does that quietly in the background and keeps mold, musty smells, and warped wood from moving in.

The trouble is that dehumidifiers all look the same on a store shelf. Here’s which ones are worth your money, which size you actually need, and the one feature I’d never skip for a basement.

How we picked

We didn’t haul a dozen dehumidifiers into a basement. Instead, we compared specs, Energy Star ratings, drain options, warranties, and noise, and read through long-term owner reviews and hands-on testing from established outlets like Better Homes & Gardens and Bob Vila. We favored brands with a solid track record and replacement parts you can actually find.

Quick picks

1. Midea Cube 50-Pint: best overall for basements

The Cube is my pick for most people, and it’s not close. Its party trick is the tank: the top section lifts off and the base expands, so it holds far more water than a typical bucket while taking up less floor space when it’s packed down. It’s also one of the quieter 50-pint units around, which matters if your basement is a finished family room and not just storage.

You can run a drain hose for nonstop operation, too. The catch is price: it usually costs more than basic 50-pint models. I think the bigger tank and lower noise earn it. Check the Midea Cube 50-Pint on Amazon.

2. GE Smart Dehumidifier 50-Pint: best for app control

If you want your phone to tell you when the bucket’s full or humidity’s creeping up, the GE Smart is the one. Better Homes & Gardens named it their best overall dehumidifier after testing it in a large basement. The app lets you set humidity and fan speed from upstairs, which is nicer than it sounds when the basement’s two flights down. See the GE Smart Dehumidifier.

3. Frigidaire 50-Pint: best no-fuss pick

Frigidaire’s 50-pint model is the plain, dependable workhorse. Straightforward buttons, a washable filter, a front bucket, and a hose connection for continuous drain. It won’t win design awards. It’ll just dry the room. And because Frigidaire is everywhere, filters and parts are easy to track down years from now. View the Frigidaire 50-Pint.

4. hOmeLabs 50-Pint: best budget basement pick

hOmeLabs is the value play. You get similar rated capacity to the big names for less money, plus the usual auto-shutoff, continuous drain, and adjustable humidity. Fit and finish isn’t quite as nice, and warranty support isn’t as established, but if the budget’s tight and you’ve got a big damp space, it’s a reasonable buy. Check hOmeLabs pricing.

5. Midea Cube 20-Pint: best for bedrooms

For a bedroom, a dorm, or the room with the dripping windows, you don’t need a 50-pint monster rattling all night. The smaller Cube keeps the same compact, quiet design in a size that makes sense for one room. Set it to 45% and let it run. See the Midea Cube 20-Pint.

6. Eva-Dry E-500: best for closets and tiny spaces

This little thing isn’t a room dehumidifier, so don’t buy it for a basement. It’s a canister full of moisture-absorbing beads. When the indicator changes color, you plug it in for a few hours to dry it out, then put it back. It’s perfect for a musty closet, a gun safe, a boat cabin, or under a sink. View the Eva-Dry E-500.

What size do you need?

Here’s something most buying guides skip. In 2019 the Department of Energy changed how dehumidifiers are rated, and the new test gives lower pint numbers for the same machine. So a “50-pint” unit sold today is roughly equal to what used to be sold as a 70-pint. Don’t let the smaller number scare you.

As a rough rule: a single bedroom or bathroom does fine with a 20- to 22-pint unit. A damp basement, or anywhere that smells musty, wants a 35- to 50-pint model. A big, wet basement that floods or sweats in summer needs a 50-pint unit with continuous drainage, at minimum. When you’re between sizes, size up. A bigger unit runs less and lasts longer.

The feature I’d never skip for a basement

Continuous drain. Emptying a bucket every day gets old in about a week, and the day you forget is the day it shuts off and the basement gets musty again. Look for a hose connection and set it over a floor drain. No floor drain nearby? Get a model with a built-in pump, which pushes water up and out to a sink or window.

Keep the humidity setting around 40% to 50%. The EPA recommends keeping indoor humidity below 60%, ideally between 30% and 50%. If your windows are fogging up, our guide to condensation on the inside of windows walks through other fixes too.

FAQ

What size dehumidifier do I need for a basement?

Most basements do well with a 35- to 50-pint dehumidifier, rated under the current Department of Energy standard. Big or very damp basements should go with 50 pints and a continuous drain hose or built-in pump.

Where should I put a dehumidifier in my basement?

Put it near the dampest area, with at least a foot of space around it for airflow, and close to a floor drain if you plan to use a hose. Keep basement windows and doors closed while it runs.

What humidity should I set my dehumidifier to?

Somewhere between 40% and 50% works for most homes. The EPA recommends keeping indoor humidity below 60%, ideally 30% to 50%, to discourage mold and dust mites.

Should I run a dehumidifier all the time?

Let the built-in humidistat decide. Set your target humidity and it cycles on and off by itself. In a damp basement it may run often in summer and barely at all in winter.

Can I use a dehumidifier in a bedroom?

Yes. Pick a smaller 20- to 22-pint model with a quiet or sleep mode, and keep it a few feet from the bed.

Why do new dehumidifiers have lower pint ratings?

The Department of Energy updated its testing method in 2019 to use cooler, more realistic conditions. The same machine now gets a lower pint rating, so a 50-pint unit today is roughly equal to an older 70-pint unit.
