If you would like to upgrade your Softener to a Softener + Filter in One, add a KDF Media Guard to your purchase at the same time and we will install it to the tank before shipping it out to you. You can still use the same valve/meter for the water softener system with a MediaGuard. No Changes Necessary. Valves Not Included
For our KDF 55 MediaGuard: B07PDB1KK9
For municipal water, KDF 55 MediaGuard removes chlorine and heavy metals, and prevents the growth of bacteria in your softener system.
For our KDF 85 MediaGuard: B07PJN729V
For Well Water, add the KDF-85 MediaGuard to remove moderate amounts of iron and hydrogen sulfide (up to 1 ppm iron and/or H2S).
