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.
