If you're dealing with a small amount of ambient moisture in a bedroom or bathroom, it might be time to invest in a compact dehumidifier. Now, there's no getting around the fact that these options are far less capable than full-size units; after all, there's a price to pay for their compact size. But compact units have advantages as well, as they're smaller, quieter, and produce less heat than their full-size siblings.
We've tested 20 dehumidifiers in total, 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 larger spaces. Check out our recommendations for the best dehumidifiers and the best dehumidifiers for bedrooms. If you're looking for a relatively space-efficient way to keep your room cool, you can also check out some of our recommendations for the best window A/Cs and the best portable A/Cs.
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 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
Basement3.6Bathroom5.8Large Room4.5Bedroom7.1Capacity2.5Noise8.0Temperature Stability8.1Type:Thermoelectric (Peltier)See all our test resultsDrain Pump:NoThe best small dehumidifier we've tested is the ProBreeze PB-03, and it's suitable for small spaces like a bedroom in an RV or just a closet. It's a fraction of the size of most full-size dehumidifiers, so you can easily squeeze it onto a shelf, bedside table, or other tight space. It generates very little heat, so you won't notice any major impact on the ambient temperature, even if you leave it running continuously. Its power draw of only 37W is pretty minimal, which is great if you plan to have it run overnight often. However, its poor dehumidification capacity means it isn't a particularly energy-efficient option either.
Performance-wise, it doesn't offer anywhere near the dehumidification capacity of a full-size machine. As a result, it'll be very slow in removing moisture from even modestly sized rooms. The ProBreeze also has a tiny water tank, but since its dehumidification rate is so low, it still takes quite a while to fill up. Thankfully, its automatic shutoff feature prevents the tank from overflowing if you leave it unattended. If you're having trouble finding it from major online retailers, check out Home Depot.

Best Budget Small Dehumidifier
Basement2.5Bathroom5.5Large Room3.5Bedroom7.4Capacity0.8Noise9.0Temperature Stability8.7Type:Thermoelectric (Peltier)See all our test resultsDrain Pump:NoIf you want to spend less on a compact dehumidifier, consider the ProBreeze PB-02. In terms of capacity, it falls even further behind the ProBreeze PB-03, meaning it's only really suited for the smallest of spaces, like a small closet or inside a set of cabinets; it won't do much to clear humidity from an entire room, even one of modest size. That said, it's even cheaper and more compact, to the point where you can set it up on a nightstand, dresser, or shelf with room to spare. Its water tank is pretty small, but like the PB-03, it takes a fair amount of time to fill up. Like its larger stablemate, it has an automatic shutoff feature, so it'll stop running once the tank is full; no need to worry about the tank overflowing if you leave it unattended while you're away from home.

Best Small Whole-Room Dehumidifier
Basement6.9Bathroom7.3Large Room7.0Bedroom7.7Capacity6.1Noise7.9Temperature Stability8.0Type:RefrigerantSee all our test resultsDrain Pump:NoIf you need a dehumidifier for a larger living space but don't want to step up to a full-size unit, the Waykar PD160B is a great intermediate choice. Its 8.5-pint dehumidification capacity is substantially greater than compact countertop models like the ProBreeze PB-02 or the ProBreeze PB-03, so it can effectively remove moisture from small to medium-sized rooms, like an apartment bedroom or office. There's little need to interact with its controls, as you can set your desired humidity level, and the Waykar will adjust its fan speed setting as needed. That's good, since adjusting settings manually is a chore: the display is dim and has poor viewing angles. If you're close to a floor drain or sink, you can configure it to drain continuously using the provided hose, though it lacks a pump that would allow it to drain into an elevated container like a bathtub or a sink.
This dehumidifier is a great option for bedrooms since the noise it produces is barely louder than a quiet hum, even at its highest fan speed, so it won't keep you up if you run it at night. It also generates very little heat, so you can position it near your bed without feeling a constant flow of warm, dry air against your face.

Eva-Dry EDV-1100:
The Eva-Dry EDV-1100 is effectively the same unit as the ProBreeze PB-02 and shares the same general strengths and weaknesses of highly compact size, low power consumption, and dismal dehumidification capacity. Of the two, buy whichever is cheaper in your home market.
