2019 doe-approved: starting in 2019 the dept. of energy began using a new testing method for all dehumidifiers. our 2019-compliant dehumidifiers have an upgraded compressor to make them more energy efficient while still maintaining the same dehumidification capacity as previous models(70 pint 2012 doe standard).
Quiet operation: you don't always see it, but that’s the point. a peak sound level of 48 decibels means you'll barely notice the dehumidifier is there. for comparison, 50 decibels is almost as loud as a secluded suburban street or a normal conversation at home.
