Dehumidifier Running Cost Lookup: Every ENERGY STAR Model
This tool loads the current list of ENERGY STAR certified dehumidifiers straight from the EPA's public database and prices each model's rated yearly energy use at your state's electricity rate.
How to read the results
- kWh/yr is ENERGY STAR's rated figure, reported by the manufacturer under the Department of Energy test procedure. It is a standardized estimate, not a measurement in your basement. When we back-calculate from each model's capacity and efficiency, the ratings correspond to roughly 1,100 hours of running per year for most models. If your unit runs much more than that (for example, around the clock all summer), your cost will be higher.
- IEF (integrated energy factor) is liters of water removed per kWh. Higher is more efficient. Compare IEF only between units of similar capacity.
- Capacity ratings changed in 2019. The DOE test now runs portable units at 65°F instead of 80°F, so today's ratings are lower than older ones for the same machine class. ENERGY STAR notes that an old "70-pint" class unit is roughly a 40 to 45-pint unit under the current rating.
- Flagged rows: a few listings report yearly kWh that is several times higher (or lower) than their own capacity and IEF would imply. We show them unchanged but flag them, since they may be data-entry errors.
