small space, high performance

ZERO is the highest performing, most compact reverse osmosis drinking water filtration system to go under the sink.

danish TECHNOLOGY build on nature


The Aquaporin Inside® technology is unique to ZERO.

A technology developed using 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.

When tap water flows through the Aquaporin Inside® membrane in the ZERO, the natural aquaporin proteins act like a super-highway for water. Keeping bacteria, viruses and pesticides out, while leaving you with great tasting tap water.
