50-Pint Dehumidifiers

A 50-pint dehumidifier, rated under the current DOE test, is the largest common portable size and suits large or very damp basements, roughly 1,000 to 4,500 sq ft depending on conditions. It equals what older listings called a 70-pint unit.

What to compare

• Check the rating basis: a listing that says "70 pint (2012 DOE)" and "50 pint (2019 DOE)" describes the same machine.
• Pump or gravity drain: models with a pump can push water up to a sink or out a window.
• Bucket size: a 50-pint unit can fill a small bucket quickly in wet weather.
• Operating temperature: check the lowest rated temperature if your basement is cool.
• Energy factor: higher liters per kWh means lower running cost.
• Weight: these units often weigh 40 lb or more, so look for handles and casters.

If your drain is above floor level, see Dehumidifiers with Pump. For quieter living areas, compare Quiet Dehumidifiers.

FAQs

What size area does a 50-pint dehumidifier cover?

Manufacturers commonly rate 50-pint models for about 1,000 to 4,500 sq ft, depending on how damp the space is. Very wet basements with standing moisture sit at the low end, and moderately damp spaces at the high end. For very wet conditions over large areas, consider two units or a whole house model.

Is a 50-pint dehumidifier the same as a 70-pint?

Usually, yes. The 70-pint figure comes from the older DOE test at 80°F. Since 2019, the same capacity is tested at 65°F and labeled about 50 pints. Compare models using the same test standard, which most listings now show alongside the old figure.

Is a bigger dehumidifier better?

Often. A larger unit reaches the target humidity faster and cycles off sooner, which can mean similar or lower energy use than an undersized unit running constantly. It costs more and is heavier. If your space is only slightly damp and small, a 22- or 35-pint unit is enough.
