About

About Ecofilter Tek Ecofilter Tek is a Canadian cleantech company pioneering a novel regenerable ion exchange resin for the sustainable removal of PFAS from water. Unlike conventional resins that rely on harsh chemicals, Ecofilter Tek’s patented Charge-Switching Technology uses only pH adjustment to regenerate the resin, making it safer, more cost-effective, and environmentally friendly. This breakthrough approach significantly reduces operational costs, waste generation, and environmental impact while delivering high efficiency in PFAS removal. Ecofilter Tek is a Québec-based cleantech company developing advanced charge-switchable polymer technologies for water treatment. Its proprietary solutions, including AmphoRes™ and AmphoPoly™, enable efficient removal of contaminants such as PFAS while improving performance, regenerability, and sustainability of filtration systems. It has developed a novel ion exchange resin for PFAS removal and it is regenerable just by NaOH at pH 11.
