If you're short on space, going smaller with your dehumidifier often comes with some tradeoffs in performance, but it doesn't have to mean settling for something ineffective. Some compact models are built for light moisture control in closets, bathrooms, or other tight spots, while others use space-saving designs to deliver enough capacity for an entire room. There are even higher capacity models that take up less floor space than you'd expect, given how much they can do.
We've tested over 20 dehumidifiers, and below are our recommendations for the best small options on the market. We make our picks based on their dehumidification performance, size, and price. You'll want to look elsewhere if you need more capacity or have a larger space to dehumidify. Check out our recommendations for the best dehumidifiers for a broader overview of the strongest options across different room sizes, or the best dehumidifiers for bedrooms if quiet operation and lower heat output are bigger priorities.
If you don't know where to start, deciding between dehumidifiers can put a damper on your day. Luckily, we've streamlined the process, buying and testing over 20 dehumidifiers from major retailers; no cherry-picked models. Our lab team then measures airflow, capacity, and more to ensure you have the data you need to make a buying decision. If you're still between models, you can compare them directly, side by side.

Best Small Dehumidifier
Basement3.5Bathroom5.9Large Room4.4Bedroom7.3Capacity2.5Noise8.8Temperature Stability7.9Type:Thermoelectric (Peltier)See all our test resultsDrain Pump:NoThe TABYIK DH-CS01 is the best small dehumidifier we've tested because of its truly compact design and light-duty moisture control. At just 10 inches tall, it's easy to fit on a bathroom counter, dresser, shelf, or at the bottom of a closet without taking up much usable space. It's also lightweight and easy to move between rooms or bring along in an RV or camper. Unlike larger compressor-based dehumidifiers, it uses a thermoelectric system, which helps keep both noise and heat output low. Its fan produces only a faint hum and raises the surrounding temperature very little, making it easy to leave running overnight or in a small, enclosed space.
Compact dehumidifiers like this usually come with major performance compromises, though. It removes moisture very slowly, so it's best for mild issues like a slightly musty closet, lingering humidity in a small bathroom, or dampness inside an RV rather than lowering the humidity throughout an entire room. It also lacks a humidistat, so it can't automatically maintain a target humidity level. There's also no continuous drainage option, so you'll need to empty the small tank manually. It does automatically shut off before the tank overflows, though.

Best Dehumidifier For Small Rooms
Basement7.1Bathroom6.9Large Room7.0Bedroom6.6Capacity6.5Noise6.6Temperature Stability6.2Type:RefrigerantSee all our test resultsDrain Pump:NoIf you need more capacity than the TABYIK DH-CS01 but still want something that's easy to tuck away, the 20-pint Midea MAD20S1QWT is a much more capable option. It's especially practical in tight spaces thanks to its collapsible cube design and fully detachable tank. If you opt for continuous drainage, you can remove the tank entirely while the unit runs, since collected water drains through a hose rather than collecting inside it, cutting the unit's overall size roughly in half. If you'd rather collect water in the tank, though, you'll need to run it fully extended. When you're done using it, the compressor section can also nest down inside the water bucket for more compact storage. It also has a humidistat that automatically maintains your target humidity level, plus Wi-Fi controls for remote monitoring or adjustment.
The trade-off is that, as a compressor-based model, it runs noticeably louder and produces more heat than the compact models like the TABYIK, so it can be more distracting in a bedroom or home office and may make a small room feel warmer over longer periods of use. Also, since there's no built-in pump, you'll need a nearby drain that sits lower than the unit if you want to use it without the tank.

Best Small 50-Pint Dehumidifier
Basement8.5Bathroom7.7Large Room7.8Bedroom6.4Capacity8.5Noise5.6Temperature Stability6.2Type:RefrigerantSee all our test resultsDrain Pump:YesWhile no 50-pint dehumidifier is truly compact, the Costco-exclusive Midea MAD50PS1AWT-C is the smallest 50-pint model we've tested, making it a particularly good choice if you need high-capacity moisture removal without giving up more floor space than necessary. Its short, shallow body is easier to work into a room than most other full-sized units, letting it tuck easily along a wall, beside furniture, or into a tighter basement or laundry area. Despite its smaller footprint, it still delivers the strong moisture-removal performance and airflow you'd expect from a 50-pint unit, so it's well-suited to larger rooms or spaces with persistent humidity. It also has a humidistat, Wi-Fi controls, and a built-in drain pump, so it can run with very little hands-on attention.
The downside, again, is noise and heat. It runs louder and produces more heat than the Midea MAD20S1QWT, making it harder to live with in close quarters, where the fan noise and added warmth are more noticeable. You'll also need a Costco membership to purchase it from Costco.

Eva-Dry EDV-1100:
The Eva-Dry EDV-1100 is slightly quieter and produces less heat than the TABYIK DH-CS01, but the TABYIK removes more moisture and has a larger tank.

ProBreeze PB-03:
The ProBreeze PB-03 is a decent alternative to the TABYIK DH-CS01 if you'd prefer a larger water tank and slightly stronger airflow. It offers similar moisture-removal performance but is larger, louder, and more expensive than the TABYIK.
