How efficient is the MARS HYDRO MH-DeHumidifier?
It files an IEF far above every other dehumidifier (all the others file 4.5 L/kWh or less), so it's left out of the class comparison and the cost figures.
A higher IEF means more water removed per kWh.
Who makes MARS HYDRO dehumidifiers?
DOE's database has no manufacturer field, so the evidence is whose model number each unit is filed under and which other brands file the same unit.
Its one basic model isn't filed by any other brand as of 2026-11-03, and the model number isn't another company's. DOE's records tie it to MARS HYDRO alone.
