Dear Achim,

We gave the Filtersorb SP to Dr.Borsanyi, Matyas Head of Water Chemistry Department of National Institute of Environmental Health, National Public Health Centre H-1450 (Gyali ut 2-6)P.O.Box.26, Hungary

He did not believe it at first. He is in charge to test all the water treatment equipments coming to Hungary for approval. He said, after he installed the Filtersorb SP in front of their distiller, made of glass, and after few month no spots on the glass. He did not believe it. So he called as after two months of testing, the glass was clear, he is preparing the certificate for scale prevention of drinking water. The inlet water is 17 dH .Budapest.

Also, one of my customer has an existing fountain. He filled it up with Filtersorb SP water, 8 days ago, and fill up always to reach the level.
" no scaling at all "
and all the existing scale ,black dirt removed from
- the wall
- from the joints
- from the skimmer
- from the glass parts
- all the parts are shiny and no scaling detected on the water level. Because of the evaporation the hardness already more than 50 dH.

Best regards,
Gyula Petro
