These 120- or 220-V resi-dential steam humidifiers were designed to provide maximum efficiency and comfort with minimal maintenance, the manu-facturer says. Both units provide an automatic flush every 12 hrs, introducing clean water into the unit, while a sacrificial anode eliminates calcium and mineral buildup in the unit on the heating element and the tank itself, says the company. Models S2000 and S2020 both produce steam, to provide maximum comfort without the need to place a heat call, says the manufacturer.
