How the media works

The core of this system’s power lies in its media blend: KDF-55 combined with catalytic carbon. KDF-55 is a specialized formulation designed to inhibit bacterial growth inside your water system by creating an environment that disrupts their life cycle. This bacteriostatic action ensures that even after filtration, bacteria are less likely to multiply and cause issues down the line. Alongside this, catalytic carbon removes chlorine and other contaminants that can cause unpleasant tastes and odors, further enhancing water quality. Together, these medias provide not just a filter but an active environment that cleans your water while protecting your home’s plumbing from bacterial colonization.

Common questions

Q? How does this system handle bacteria and coliform differently than a standard filter?
A The Autotrol system uses KDF-55 media with catalytic carbon, which not only physically filters but also suppresses bacterial growth chemically, reducing the risk of regrowth—something standard filters often can’t achieve.

Q? Why is the Autotrol 263 backwashing valve important for bacteria removal?
A This valve automates the backwash and regeneration process, flushing out trapped contaminants and refreshing the media to maintain consistent bacteria suppression, ensuring your system performs optimally without manual intervention.

Q? Is this system enough on its own for full disinfection?
A While the system dramatically reduces bacteria and coliform, pairing it with a UV stage (part of our well water bundle) provides complete disinfection, eliminating bacteria that pass through filtration for total peace of mind.
