We compared five 50-pint dehumidifiers on real specs, manufacturer data, and independent lab tests where available, including bucket size, noise levels, and the 2019 pint-rating change.
Among the five units here, the Midea Cube with Pump is the strongest overall pick: it's the only one with independent bench-test numbers showing genuinely low noise (42.5-49 dB) and it carries the largest water reservoir of the group at roughly 4.2 gallons, so it needs emptying less often even without the drain hose hooked up. Its one real knock is software, not hardware, a reviewer flagged an in-app notice that the companion Midea Air app is no longer being actively updated, which matters if smart scheduling is why you're buying it. The Frigidaire FFAD5033W1 is a widely-stocked plain 50-pint option, though some retailers now list it as discontinued in favor of the WiFi-enabled FHDD5033W1, and an independent sound-meter test measured it noticeably louder than Frigidaire's own spec sheet suggests. Skip the original Honeywell TP70WKN unless you're fine buying it Renewed, new stock has shifted to the TP70WKNR, and treat the GE listing as the pick that needs the most homework, since GE's own site currently shows several recent 50-pint model numbers as discontinued.

Buyer checklist
We pulled core specs from each manufacturer's own product pages and spec sheets, cross-checked pint capacity and coverage claims against the current Amazon listings, and layered in independent bench-test data (noise in dB, tank size, long-term reliability) from outlets like HouseFresh and dehumidifierbuyersguide.com wherever that testing existed for the specific model. We did not run our own hands-on tests. Where manufacturer marketing and independent measurements disagreed, or where a brand's own site listed a model as discontinued, we say so directly rather than picking a number silently.
Not necessarily. Pint capacity is measured under a specific lab test, and two units with the same rating can differ in coverage area, bucket size, and real-world noise. A 50-pint unit tested under the newer, more realistic standard can outperform an older 70-pint unit tested under looser conditions, even though its number looks smaller.
Before 2019, most dehumidifiers were tested at 80°F and 60% relative humidity. The current DOE test procedure runs at 65°F, a temperature closer to an actual basement, and cooler air simply holds less moisture to remove. That single change pushed the old 30/50/70-pint tiers down to 20/30/50-pint tiers for the same physical hardware, which is why several older '70-pint' models, including versions of the Honeywell and hOmeLabs units in this guide, are now sold as '50-pint' without any change to the machine itself.
Only if you want to avoid emptying the bucket. A basic gravity drain works if the hose can run continuously downhill to a floor drain or sump; if it can't, you need a model with a built-in condensate pump (or an add-on pump) to push water uphill or over a distance, which is the difference between the pump and non-pump versions of the same product line in this guide.
