Maintain your home's most comfortable humidity level and protect your hardwood flooring and woodwork with Honeywell's HE420 Whole-House Steam-Powered Humidifier. The exclusive technology of the HE420 delivers consistent and reliable moisture on-demand, even when your heating and cooling system isn't running. You'll also save money on energy bills because humidified air feels warmer than dry air, allowing you to turn down your thermostat setting.
