What are water efficiency classes?

In order to help you choose the right product, we rated each of our devices to its water efficiency grade.

Water efficiency classes are determined separately for each category in our offer (for example: kitchen faucet or bathroom faucet).

The higher the grade, the bigger the savings.

When choosing a product consider also other product characteristics, such as limescale resistance or special features.
