While the steam humidifier and its available filtration options help to address the issue of water quality and
hardness, homes with extreme hard water problems should consider using a whole house water softener as
the primary filtration device. Use of a whole house water softener will help protect the humidifier from excessive
maintenance requirements as well as undue wear and tear in homes with hard water.
In applications with a water softener, it is critical for the steam humidifier to draw its water supply from the cold
water line after the water softener.
Note: Be sure to check all local plumbing codes before beginning installation.
