The 2019 dehumidifier label change — the same machine is rated lower now

The June-2019 DOE test moved from 80°F to 65°F, dropping ratings ~30%: an old 70-pint is now labeled 50. Buy by the current label.

A dehumidifier unit in the center with two labels. The pre-2019 amber label (tested at 80°F) reads 70 pints; the current blue label (tested at 65°F) reads 50 pints for the same machine, connected by a times-0.71 arrow. A red warning below notes that an old chart’s "50-pint" is today’s "35-pint," so sizing from an old chart against a new box buys a unit one size too small. — Source: DOE 10 CFR 430 (June 2019)
