If you are shopping for a 70 pint dehumidifier, you have probably noticed that the big brands do not sell one any more. They did not shrink their machines. In 2019 the Department of Energy moved the capacity test from 80F to 65F, and colder air holds less water, so the same unit now earns a smaller number. Honeywell and Hisense, for example, sold their former 70 pint models as "50 pint (70 pint pre-2019)".
ENERGY STAR's certified list makes the point clearly: of 552 certified portable dehumidifiers we checked in November 2026, none is rated above 50 pints a day on the current test. So a modern 50 pint unit is today's 70 pint. If you need more than that, you move up to heavy duty crawl space and whole-home machines, which are rated at the older 80F condition.
| Old rating (80F test, through 2019) | Approximate new rating (65F test, 2020 on) |
|---|---|
| 30 | 20 |
| 40 | 25 |
| 50 | 30 |
| 55 | 30 to 35 |
| 60 | 35 |
| 70 | 40 to 45 |
| 90 | 55 |
Source: ENERGY STAR, Dehumidifier Testing and Capacity, which calls this "a rough correlation" that varies by model. Some makers label their own conversions differently: Honeywell and Hisense, for example, market former 70-pint models as 50 pints under the 2019 standard.

Best large room dehumidifier
For a single large room such as a family room or open-plan living area, a 50 pint portable is the right size. It is the most powerful dehumidifier you can buy in a normal portable format, and ENERGY STAR's chart puts 50 pints at the top of the range for a wet room under 2,000 sq ft. Choose a model with a pump or hose if you do not want to empty a bucket, and put it where air can circulate around it.
Dehumidifier for 1000 sq ft
A dehumidifier for 1000 sq ft depends on how damp the space is, not just its size. Using ENERGY STAR's sizing chart for spaces under 2,000 sq ft: 20 to 30 pints if it is only slightly damp, 25 to 40 pints if it is very damp, and 30 to 50 pints if it is wet. ENERGY STAR adds that it is better to oversize than undersize.
| Condition before dehumidifying | Room under 2,000 sq ft (pints/day) | Space over 2,000 sq ft (pints/day) |
|---|---|---|
| Slightly to moderately damp feels damp, musty odor at times; about 50 to 75% RH | 20 to 30 | 30+ |
| Very damp always feels and smells damp, damp spots on walls or floor; about 75 to 90% RH | 25 to 40 | 40+ |
| Wet walls or floor sweat, seepage, laundry drying; about 90 to 100% RH | 30 to 50 | 50+ |
Source: ENERGY STAR dehumidifier buying guidance. ENERGY STAR adds: "it's better to oversize than undersize."
