YesWhat we know
Where it stands
This model is not on the EPA’s list of certified dehumidifiers (checked Oct 16, 2026). Figures on this page come from the company that filed it.
- Rated 50 pints a day in its filing with the Department of Energy.DOE class: portable, over 25 and up to 50 pints a day. DOE basic model MAD50P1ZWS.
- Its efficiency, 1.80 liters per kWh, is 0.20 above the federal minimum for portables rated over 25 and up to 50 pints a day.That minimum is 1.60 L/kWh, for units made since June 13, 2019.
- That beats 127 of the 452 certified portable models.Their median is 2.01 L/kWh, from 1.70 to 2.24.
- Removing 100 pints costs $4.81 in the United States, against $4.31 at the median of those certified models.Same 2019 DOE test on both sides, so the figures compare directly.
- In the DOE database, this model number appears under the Midea name only.
- The EPA list has 49 certified Midea models, from the MAD20S1QWT to the MDUDT-50AEN8-BB0F, filed by GD Midea Air-Conditioning Equipment, which also files Pelonis.
Good to know
What “not on the EPA list” means
The model is missing from the EPA’s dataset on the date we checked. That says nothing about its safety or build quality. Its capacity and efficiency come from the filing with the Department of Energy. That filing uses the same 2019 test as the models on the list, so the cost to remove 100 pints compares directly. No yearly energy figure is published for it.

Run for a whole day at its rating, the MAD50P1ZWS removes 50 pints, about 6.3 gallons, on roughly 13.1 kWh. In the United States, that’s $2.41.
Its rating comes from a DOE test at 65°F and 60% humidity. In cooler air at that humidity, the MAD50P1ZWS pulls out less than 50 pints a day.
Those 6.3 gallons need a way out: a hose to a drain, a pump, or a bucket you empty. Our sources don’t say which ones the MAD50P1ZWS has.
