Optimized carbon performance on repeat
Your spent carbon is a strategic asset, and GAC reactivation is your key defense against rising costs and long-term environmental liability. While others simply dispose of spent media, Calgon Carbon closes the loop, transforming your spent carbon into a high-performance solution that outlasts and outperforms the status quo.
Thermal reactivation destroys PFAS to near non-detect levels, avoiding the landfill.
Shield your budget from virgin carbon price volatility with a circular supply chain.
Access North America’s largest RCRA-permitted reactivation network.
Cut CO2 impact by 80% and meet sustainability goals with a recycled solution.
Water utilities value predictability. So do we.
By switching to a closed-loop GAC reactivation strategy with Filtrasorb Rx, you replace operational anxiety with a concrete pillar of technical certainty. Move toward a more resilient infrastructure and, above all, say goodbye to:
- Disposal fees and unpredictable carbon price swings
- PFAS liability lingering on your books
- Supply disruptions and media shortages
- High-emissions, single-use supply chain
Generic custom municipal reactivation solutions add uncertainty at every stage of ownership.
Filtrasorb Rx delivers the tailored performance others can’t.

Frequently Asked Questions:
Why did Calgon Carbon move away from the name “CMR”?
CMR describes a process, not a product.
Filtrasorb Rx places reactivated carbon under the trusted Filtrasorb master brand, creating a name that everyone can recognize, specify, and defend in budgets.
Calgon Carbon’s peer-reviewed reactivation process is only one aspect to realizing the reactivated product performance. The starting feedstock is another critical part to performance.
How does Filtrasorb Rx differ from generic reactivated carbon?
Filtrasorb Rx is:
- Your carbon returned to you, not pooled or swapped
- Based on Filtrasorb virgin grades
- Backed by peer‑reviewed, full‑scale reactivation studies
- Our process is proven to remove organics like PFAS from the spent carbon to non-detect levels
- Our process is proven to destroy PFAS to >99.9% Destruction Removal Efficiency
- Supported by Calgon Carbon’s technical, logistics, and field service teams
- The only reactivated media to use Filtrasorb virgin carbon for make-up supply post reactivation.
Other reactivated carbons may not offer the same level of consistency, transparency, or accountability.
What changes for current customers who use Calgon Carbon for reactivation?
Here’s what has changed:
- Product name on documentation and packaging transitions to Filtrasorb Rx
