The top 5 at a glance
A dehumidifier pulls water out of damp air and collects it in a tank, or sends it down a hose to a floor drain. Compressor models do the heavy work, from a bedroom to a whole basement. Thermoelectric minis are smaller and quieter, but collect far less water, so they suit a closet, a bathroom or a small bedroom.
Dehumidifiers are sized in pints a day, and makers quote the figure in hot, very humid test conditions, so a cooler basement gets less than the box says: the makers of the 80-pint machines here give 56 pints at 86°F and 80% humidity. Every one comes with a drain hose, which lets it run nonstop instead of stopping when the tank fills.
What matters
- 30 pints a day for a damp room, 80 for wet basements.
- A humidity setting, so it stops once the air is dry enough.
- Energy Star certification, for a machine that runs for hours.
- A low decibel rating for a bedroom or home office.
#1Kesnos 30-Pint Energy Star Dehumidifier
$100–$150
A compressor dehumidifier that pulls up to 30 pints a day and can take a room down to 30% humidity, Energy Star certified for 2025 and rated at 36 dB, quiet enough for a bedroom. It rolls on casters, and with the included drain hose it can run nonstop in a basement.
What owners say: Owners say it keeps basements dry and clears condensation quickly and quietly, and they like that it doesn’t look out of place in a room.
A closer look: Turbo mode is the one for drying laundry on a wet day, and Comfort for overnight in a bedroom. The 0.39 gallon tank shuts the machine off when full, so in a damp basement fit the included 3.3 ft hose instead and run it to a floor drain.
- Down to 30% humidity
- Energy Star 2025
- Shuts off when full
- Auto defrost
- Restarts after a power outage

#2AEOCKY RHEA-001 80-Pint Energy Star Dehumidifier
$200–$300
Big enough for a damp basement or a whole floor: up to 80 pints a day in hot, humid conditions and 56 in a warm basement, with an Energy Star Most Efficient 2025 rating and a fan that starts at 44 dB. AEOCKY says it keeps working below 65°F, where compressor models tend to frost up.
What owners say: Owners say it runs quietly and keeps a basement properly dry, was easy to set up and costs far less than the big names. Water collection and how long it lasts divide them, and some empty the tank every two or three days.
A closer look: At 31 lb it’s one to set up and leave, ideally near a floor drain: the hose and a garden hose adapter, packed in the tank, let it run nonstop. It remembers its settings after a power outage, so it can go on a smart plug and restart by itself.
- Energy Star Most Efficient 2025
- Keeps working below 65°F
- Garden hose adapter included
- 3-year coverage
Best for: Whole floors and cool, damp spaces
- Type

#3GoGuess YC3 21-Pint Compressor Dehumidifier
$100–$150
A small compressor dehumidifier, 17 in tall, for a bedroom, home office or RV where a mini isn’t enough and a 30-pint machine is more than the room needs. It pulls up to 21 pints a day in hot, humid test conditions, holds the humidity anywhere from 30% to 80% and runs at 40 dB.
What owners say: It gets to work right away, owners say, keeping rooms and even a 1,000 sq ft basement drier while staying quiet and small enough to tuck out of the way. The tank is easy to empty.
A closer look: The color-changing light shows the room’s humidity at a glance, even with the machine switched off, which helps judge whether a room needs it at all. Sleep mode turns the display off for a bedroom. The 0.61 gallon tank fills quickly in a damp space, so fit the 3.28 ft hose where it can run to a drain.
- Set humidity 30–80%
- Shows humidity even when off
- Sleep mode turns display off
- Washable filter
- 2-year warranty
Best for: Single rooms and RVs
- Type
- Compressor
- Pints a day
- 21 pints
- Tank
- 0.61 gal
- Noise
- 40 dB
- Laundry mode
- Turbo mode
- Extras

#4boglvr CT6 Mini Dehumidifier with Drain Hose (98 oz tank)
$50–$75
A thermoelectric mini that takes a drain hose, so it can run nonstop over a drain in a bathroom, laundry room or RV instead of stopping when its 98 fl oz tank fills. Sleep mode runs under 30 dB, and an 8, 16 or 24-hour timer switches it off.
What owners say: Owners find it effective, simple to use, very quiet and easy to clean. Reliability splits them: some run it all night without trouble, while a few had one stop within days.
Heads up: It’s for a small room or a closet: thermoelectric minis collect far less water than the compressor models here, whatever the box says about square feet.
A closer look: A hidden slot takes an aroma pad, and the washable filter cotton, with a spare in the box, rinses clean under the faucet. In a damp laundry room or camper, connect the hose and set it where the water can drain by gravity, and there’s no tank to empty.
- Hidden aroma pad slot
- Washable filter, spare included
- Red light when full
- Carry handle
- Weighs 5.5 lb
Best for: Small rooms with a drain
- Type
- Thermoelectric
- Pints a day
- About 2 pints
- Tank
- 0.77 gal
- Noise
- Under 30 dB (sleep)
- Laundry mode

#5KNKA PD30MA-20 80-Pint Energy Star Dehumidifier
$150–$200
An 80-pint dehumidifier for basements and large rooms that runs at 40 to 45 dB, with a Dry mode for laundry, a humidity setting from 30% to 80% and a light that changes color with the room’s humidity. It rolls on 360° casters and has built-in cord storage.
Heads up: Let it stand upright for 24 hours before switching it on the first time, as KNKA advises, and keep it upright while it runs.
A closer look: Auto mode holds the room at 50%, a sensible level for a basement. The 1.45 gallon tank shuts it off when full; for a wet basement, run the 6.56 ft hose to a drain, or add KNKA’s 2.64 gallon external tank, sold separately. Close the doors and windows while it works.
- Auto mode keeps 50% humidity
- Set humidity 30–80%
