Hans Vestlund

Nynäshamn, Sweden

“My wife is very happy, and we swapped the wine for water last Friday.”

Prior to the installation of Fors M, Hans has tried several different solutions like carbon filters and sand filters, but he wasn’t satisfied with the result. The installation was handled by SWTs distributor CE Vattenteknik during summer 2021 and the system has exceeded Hans expectations since then.
