Your carbon has already done the work.
Now watch Filtrasorb® Rx do it again.
Calgon Carbon’s proprietary reactivation process transforms spent carbon into Filtrasorb Rx, a high‑performance media engineered to remove PFAS and other challenging contaminants with a measured DRE > 99.9%. What leaves your system as spent carbon returns to you as Filtrasorb Rx.
What makes Filtrasorb Rx different?
Generic reactivated carbon is a commodity. Other suppliers can offer it, and most treat it that way. Filtrasorb Rx is your Filtrasorb carbon, returned to you, engineered for your specific system and water profile. A premium solution built for proven PFAS destruction and peace of mind.
Here's what you can expect:
“Prescribed” for your water profile
Reactivated to the same quality standards as our virgin Filtrasorb grades.
Proven PFAS removal and destruction
Our GAC removes PFAS. Reactivation destroys it at a measured DRE exceeding 99.9%.
Same quality as virgin carbon
Reactivated to the same quality standards as our virgin Filtrasorb grades.
Lower total cost of ownership
A defined solution that avoids disposal fees and reduces environmental liability.
With Filtrasorb Rx, performance comes standard.
So does certainty.
Most custom municipal reactivation solutions seem like a straightforward service; however, the hidden costs of generic reactivated carbon stack up quickly:
- Generic reactivation lacks peer-reviewed research.
- Not optimized for your water profile or objectives.
- No performance baseline to hold suppliers accountable.
- Unpredictable change-out schedules strain your budget.
Generic custom municipal reactivation solutions add uncertainty at every stage of ownership.
Filtrasorb Rx delivers the tailored performance others can’t.
“Filtrasorb Rx delivers performance, supply chain confidence, and a proven alternative to rising disposal costs and liability. For us, that is what pure water, clean air, and a better world means in practice.”
