Hi Richard,

DC units can completely solve the humidity gambit, at least where I live 4%
to 84% each year. They just need to have enough wattage for the highest
possible humidity level and have the pads changed 4 times per year. And be
properly installed with back/bottom covers. And "fed" water as needed.
