The Orono, Maine-based startup makes ceramic water filters that use the “size and shape” of DNA as a template to remove ultrafine water impurities. (More on how it works here.)

The company wants to see its technology adopted for industrial wastewater treatment. “Under ‘business as usual’ the world’s water needs will exceed supply by 40 percent by 2030,” Cerahelix’s Susan MacKay told Maine Startups Insider.

Cerahelix’s $2 million funding round was led by Shanghai-based PureTerra Ventures with backing from Maine Venture Fund and Propel(x).
