How we pick

How we pick. Certified portable models rated 20–25 pints a day, the units sold as 20 to 25 pints. Each one is sold by a store we link to. One pick per need: no app, a Wi-Fi app, and sold by the brand. Within each need, the lowest yearly energy use wins, then the higher efficiency. Stores never pay for a place.

Questions

What people ask before buying

Who needs a 22-pint dehumidifier?

By the ENERGY STAR table, 22 pints a day fits a damp space under 2,000 sq ft.

That’s a room that smells musty now and then, with no damp spots on the walls or floor.

How much does a 22-pint dehumidifier cost to run?

EPA list, Oct 15, 2026 · EIA, July 2026
Are there smaller certified units?

Yes, 61 certified portables are rated under 20 pints a day. The ENERGY STAR table starts at 20, so we don’t pick from them here.

EPA list, Oct 15, 2026
Is a 22-pint unit enough for a basement?

Only a damp one. Under 2,000 sq ft, ENERGY STAR suggests 20–30 pints for a damp space. A very damp one needs 25–40, a wet one 30–50.
