While the TrueSTEAM 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 TrueSTEAM 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.

PRACTICE
Use TrueSTEAM with water that is less than 1 grain per
gallon hardness. A properly functioning water softener will
accomplish this.
