@redenigma Gave up on the usual outlets and bought a couple of AirCare units from Grainger. Floor model for the music room and "tabletop" (still pretty big) for the bedroom. Have humidity sensor built it, multi-speed, both use the same filter. Simple evaporative units.
@redenigma oops....I have a Grainger closer than HD, so that's not a problem. Sorry for your problem. We used to have Vicks, Homesick, etc - the evaporative always died quickly, can't take the white dust from electrostatics (ever try cleaning it out of all the nooks and crannies of an electric guitar?).
