Big compressor models are rated in pints per day; compact and mini units are usually listed by tank size, because they pull far less water. Do not compare a 95 oz tank with a 50-pint rating: they are different leagues.

Compressor, thermoelectric or desiccant?
Compressor: the one that really dries a space
It works like a small air conditioner: a cold coil condenses the moisture and drips it into the bucket. It is the most efficient way to remove a lot of water, which is why nearly every 35- and 50-pint unit sold in the US is a compressor model. The trade-off: it weighs 35–45 lb, makes a steady fan-and-fridge hum and loses capacity below about 60 °F (15 °C).
Thermoelectric (Peltier): small, quiet and cheap
No compressor, just a chip that gets cold on one side. They draw only 20–50 W and are nearly silent, but they pull a few ounces of water a day, not pints. Perfect for a closet, a small bathroom or an RV; useless for a basement.
Desiccant: the cold-weather specialist
An absorbent wheel or silica cartridge traps moisture, so it keeps working in cold garages, crawl spaces and boats where a compressor struggles. Cordless rechargeable units use the same principle on a tiny scale: they absorb for weeks and you plug them in overnight to dry them out.
How to choose a dehumidifier in 5 steps
- Measure first. A cheap hygrometer tells you whether you are at 55% (fine) or 75% (problem). Aim for 40–50% indoors. See our guide to ideal indoor humidity.
- Size it by square footage and dampness. Check the current pint rating, not old marketing numbers.
- Plan the drainage. If it will run all summer in a basement, a drain hose to a floor drain or sump saves you from emptying a bucket twice a day. Some units add a pump to push water up into a sink or out a window.
- Check the noise. In a bedroom, look for a sleep mode, a dimmable display and a published dB rating.
- Look for Energy Star. Certified units remove more water per kWh, which adds up over a long, humid summer.
What it really costs to run
With the US average residential rate of roughly 16–18 cents per kWh, a 50-pint unit running 8 hours a day costs about the same as a window AC: $18–29 a month. A compact model is usually under $10, and a mini thermoelectric about $3 even running around the clock. Thanks to the humidistat, real costs tend to be lower than these estimates because the compressor rests once the target is reached. Run your own numbers with our dehumidifier electricity calculator.
Get more out of any dehumidifier
- Run it in a closed room or a closed-off basement so it is only drying the space you care about.
- Pair it with ventilation: run the bathroom fan during and 20 minutes after every shower.
- Keep it on a hard, level surface and empty or drain it before the tank fills.
- If you already have black spots on walls, clean them first: here is how to remove mold from walls.

Frequently asked questions
What size dehumidifier do I need?
Rough rule under the current DOE ratings: a mini unit for closets and small bathrooms, about 20–22 pints/day for a bedroom up to 500 sq ft, 35 pints for 500–1,500 sq ft and 50 pints for a damp basement or anything bigger. Size up one step if you see mold, wet walls or standing water. Our calculator gives you a number in 10 seconds.
Is it OK to run a dehumidifier all the time?
Yes. Modern units have a built-in humidistat: set the target to 45–50% and the compressor shuts off when the room gets there and kicks back on when humidity climbs. In a basement it is normal for it to run every day from late spring to early fall.
Is a 50-pint dehumidifier too big for one room?
Not really. A bigger unit reaches the target faster and then cycles off, so it does not necessarily use more electricity. The downsides are size, weight, noise and price. An undersized unit is the worse mistake: it runs nonstop and never gets the room dry.
Why did dehumidifier pint ratings drop in 2019?
The Department of Energy changed the test from 80 °F (27 °C) to 65 °F (18 °C), which is closer to a real basement. The same machine that used to be sold as a 70-pint unit is now labeled about 50 pints. Nothing got weaker; only the label changed.
Where should I put a dehumidifier?
In the dampest area, at least 6–12 inches from walls and furniture so air can flow around it, with doors and windows closed. In a basement, put it near the source of moisture and close to a floor drain or sump if you want continuous drainage.
How much does it cost to run a dehumidifier?
A 50-pint unit draws roughly 450–700 W. Running 8 hours a day at about 17 cents per kWh, that is around $18–29 a month. A mini thermoelectric unit costs about $3 a month even running 24/7. Energy Star models remove more water per kWh.
