How efficient are SEMKAP dehumidifiers?

Of the 33 SEMKAP dehumidifiers, none files a higher IEF than the class median: 33 fall below it.

A higher IEF means more water removed per kWh.

Who makes SEMKAP 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.

None of the 33 SEMKAP basic models is filed by another brand as of 2026-11-03, and none uses another company's model number. DOE's records tie them to SEMKAP alone.

How much does a SEMKAP dehumidifier cost to run?

Running nonstop at DOE's test conditions, the 33 SEMKAP dehumidifiers with both figures use 2.91 to 2.91 kWh a day. That's about 53¢ to 53¢ a day, or $15.86 to $15.86 for 30 days.

Real use cycles on and off with the humidity, so these are the upper figures for a day of nonstop running.

At 18.16¢ per kWh, the US average residential price for August 2026 (EIA Electric Power Monthly, table 5.6.A). Worked out from the certified figures.

Questions about SEMKAP

Is SEMKAP a good dehumidifier brand?

How its 33 dehumidifiers compare on efficiency with their DOE class is above. All 33 are filed under SEMKAP alone. We don't test reliability, noise or build quality, so we can't rank brands on those. How we compare models.

Does SEMKAP make a 50 pint dehumidifier?

No current DOE record shows one as of 2026-11-03. Its largest, SEMKAP CAS-CF12(W)-US, certifies 8 pints/day under the 2019 DOE test. Boxes that quote the older 80°F test read higher for the same unit. How the 2019 test changed pint ratings.

Which SEMKAP dehumidifier is the most efficient for its size?

SEMKAP CAS-CF12(W)-US, SEMKAP D035B, SEMKAP DH1800S and 30 more tie at IEF 1.3: tied with 62 others at DOE's 1.30 minimum.
