Dehumidifier Sizes: What Pint Rating You Need
Dehumidifier size is pints of water removed per day; ENERGY STAR suggests 20 to 50 pints for a room under 2,000 square feet, and ratings since 2020 run lower.

The short answer
A dehumidifier's size is its capacity: how many pints of water it can pull out of the air in 24 hours. Pick it from two things, the size of the space and how damp it is. ENERGY STAR's sizing table and its advice that it is better to oversize than undersize are the simplest guide.
Sizing chart
ENERGY STAR gives these capacities, in pints per day, by how damp the space is without a dehumidifier:
| How damp the space is | Room under 2,000 sq ft | Room over 2,000 sq ft |
|---|---|---|
| Slightly to moderately damp (50 to 75% humidity) | 20 to 30 pints | 30+ pints |
| Very damp (75 to 90% humidity) | 25 to 40 pints | 40+ pints |
| Wet (90 to 100% humidity) | 30 to 50 pints | 50+ pints |
If you are replacing an old unit, ENERGY STAR suggests estimating from how much water you empty from the bucket each day.
Why pint ratings dropped in 2020
If you shopped for a dehumidifier years ago, today's numbers look smaller. The unit did not shrink; the test changed. ENERGY STAR explains that the Department of Energy test now runs portable units at 65°F instead of 80°F, closer to a basement, and cooler air holds less water. Lower ratings began appearing in early 2020.
ENERGY STAR lists these approximate matches for portable units:
| Old rating (through 2019) | New rating (2020 on) |
|---|---|
| 30 pints | 20 pints |
| 40 pints | 25 pints |
| 50 pints | 30 pints |
| 60 pints | 35 pints |
| 70 pints | 40 to 45 pints |
| 90 pints | 55 pints |
So an old "70 pint" model and a new 40 to 45 pint model can remove about the same amount of water. ENERGY STAR notes the change varies by model, and the maker can confirm the exact figure. When you compare listings, check whether a rating is under the old or new test.
Efficiency and cold rooms
ENERGY STAR certified dehumidifiers use 20% less energy than standard units that remove the same amount of moisture. Efficiency is rated in liters of water removed per kWh; a higher number is better. 24 dehumidifiers on Wiki Shopping list ENERGY STAR.
For a space that often drops below 65°F, such as a basement in winter, ENERGY STAR suggests a unit rated for low temperatures or one with an anti-frost sensor. For a whole house in a humid climate with central air, it suggests a whole-home unit sized by an HVAC professional.
