Thank you for visiting us!

The AQUATECH AMSTERDAM 2017 is over - time for a short resume and to say thank you.

The exhibition in Amsterdam is always a good place to maintain personal contact with our customers - but also to establish new, interesting contacts. This year we met many professional visitors from more than 30 different countries on our booth and informed them about our EVERZIT® filter media.


Thank you  for your visit on our stand during the Wasser Berlin.

Numerous visitors received information about our EVERZIT filter materials for the treatment of water.
To start with EVERZIT N for multi-layer filtration to EVERZIT Carbonate for the deacidification or hardening, the  EVERZIT Mn for catalytic demanganization and EVERZIT As for the adsorption of arsenic, cadmium or copper. A lot of interesting discussions took place and
many contacts were made.

Furthermore, many visitors wanted to get information about our new and most modern...

Continuous outstanding quality of EVERZIT® N even after 2018!

With the construction of the new and most modern factory in Ibbenbüren EVERS set a clear sign. The leading producer of anthracite filter material (EVERZIT® N) guarantees that the customers will be supplied with high quality anthracite even after 2018 thus preventing any doubt.

This reliability is very important because from 2019 on there will not be any more production of coal in Germany and for that reason the anthracite form Ibbenbüren that has been used so far will no longer be available.
