Product Overview

Say hello to the power of steam. Our efficient ComfortSteam humidifiers combine the purity of electrode-based steam humidification with the automation of electronic monitoring and control so you can enjoy both easy-to-breathe air and low system maintenance. This complete, easy-to-implement whole-house humidifier was initially designed for commercial and industrial applications, and we’re proud to offer the same professional level of performance at a reduced cost for home use. The CFS20 at 115 VAC can deliver 11.5 gallons per day of steam output. Supporting higher capacity requirements, the CFS22 powered at 230 VAC delivers double the output to 23 gallons per day. Both the CFS20 and CFS22 are ETL-listed.
