Aquaporin Inside

All of our products contain aquaporins, the proteins responsible for transporting and purifying water in all living cells. Billions of years of evolution have made aquaporins super-efficient and super-selective, far better than any man-made water filter.

By incorporating aquaporins into our biomimetic membranes, we enable you to tailor-clean water faster and more energy-efficiently than ever before.
