About instrAction

instrAction GmbH develops and produces selective absorber resins based on iA technology (Intelligent Absorber) for the removal of PFAS, heavy metals, bacteria and other contaminants from water. Having emerged from pharmaceutical research and development, the company has evolved its purification expertise into an absorber platform for complex water challenges. The resins are engineered at the molecular level to specifically detect and bind certain contaminants while preserving health-relevant elements such as calcium and magnesium. Trademarks include MetCap® and BacCap® as well as the patented PFAS filter technology. Together with partners such as filbec and Carbonit, filter cartridges are created, for example a carbon block with nanofibers (pore size 0.3 µm) combined with iA absorber technology. Fields of application range from point-of-use drinking water filtration to municipal and industrial water treatment and the recovery of precious metals from wastewater. The company has been headquartered in the Technology Park Heidelberg since 2020.

Processes & Technologies

iA absorber resin technology

Selective absorber resins that specifically bind PFAS, heavy metals (lead, cadmium, chromium) and precious metals, and are regenerable or safely recyclable.

MetCap®

MetCap® resin technology

Removes toxic metals such as lead, cadmium and chromium from drinking water in a single filtration step.

BacCap®

BacCap® resin technology

Removes pathogens from drinking water while preserving healthy minerals.

CB-NF

Carbon block with nanofibers

Filter cartridge produced in cooperation with filbec, featuring a homogeneous pore size of 0.3 µm, combined with iA absorber technology.
