If you live in a humid area, the best 70-pint dehumidifiers can remove up to 70 pints (or 8.75 gallons) of moisture from the air every 24 hours and have built-in hose connections, so the water can automatically empty itself into a nearby sink or drain. (However, many also have water tanks if you'd prefer to empty manually.) To zero in on the best unit for you, consider the size, gallon capacity, intended square footage, and extra features.
Size and gallon capacity often go hand-in-hand: The larger your dehumidifier, the more moisture taken out of the air it can typically hold — but the less compact it'll be. Smaller units are better for those with limited space, but will likely require more frequent emptying if you don't have a hose (usually sold separately) hooked up. Next, measure the space you'd like to dehumidify. For reference, 30-pint dehumidifiers are ideal for bedrooms and other smaller spaces, and a 70-pint dehumidifier should be able to tackle areas 1,500 square feet and larger.
Finally, check out the additional features. Fan speeds, built-in timers, and automatic humidity sensors are all extremely useful, and will help you customize your dehumidifier so it suits your specific needs. Wheels and handles are helpful for portability, but they're not necessary if you plan on keeping your unit in one place.
With all that in mind, here are the three best 70-pint dehumidifiers on Amazon.
