The COMFORTSTEAM™ CFS20 & 22 Self-Generating Electronic Steam Humidifiers combine the purity of electrodebased steam humidification with the automation of electronic monitoring and control to provide a complete, easy-to-implement solution for your high capacity residential applications. This same design was proven in commercial and industrial applications and now has been cost-reduced, offering the same professional level of performance to residential markets.

The CFS20 at 115VAC can deliver 11.5 gallons per day of steam output. Supporting higher capacity requirements, the CFS22 powered at 230VAC delivers double the output to 23 gallons per day. Both the CFS20 & CFS22 are ETL listed.
