On this page you will find the various analyses carried out by an independent third-party laboratory on a number of pollutants filtered by a British Berkefeld® system.
These analyses were carried out for the Ultra Sterasyl and Ultra Fluoride cartridges, which are developments of the Super Sterasyl and Sterasyl cartridges.
The analyses were carried out on volumes of water representing twice the recommended life of the cartridges. This is a guarantee of quality, performance and safety for the consumer.
