Product Feature: Honeywell TrueSTEAM™ Humidification System

• Moisture on Demand - TrueSTEAM works by producing its own steam independent of equipment operation, so your home gets moisture when you need it most.
• Eco-Friendly - TrueSTEAM is the most eco-friendly way to humidify your home, because for every 1 gallon of water used, 1 gallon of humidification is produced.
• "True Steam" - While other humidifiers rely on moisture-filled pads that can be susceptible to bacteria growth in the water and the airstream, TrueSTEAM delivers "true steam" - the cleanest form of humidification.
• Out of Sight, Out of Mind - TrueSTEAM is installed out-of-sight by your heating and cooling professional into your home's central heating and cooling system. You can forget about having to fill clunky, portable units, because TrueSTEAM automatically fills itself. 
• Whole-House Solution - Installs directly or remotely to your furnace to deliver moisture throughout your entire home.
• Minimal Maintenance - Simply clean once a year with soap and water and the rest of the time it cleans itself automatically.
