Berkey® - Do Black Berkey® water filters contain silver?

Absolutely ! Silver, a powerful antimicrobial agent, plays an essential role within each Black Berkey® element by ensuring its self-sterilization. This use of silver has been carefully verified through in-depth analyzes carried out by an independent laboratory. The results could not be more reassuring: the silver used remains solidly integrated, without the slightest dissolution in the purified water.

The conclusions of the analysis are categorical: "All control samples, whether the reserve samples, the positive and negative analytical controls, as well as the negative control taken before the introduction of the elements, demonstrated compliant and acceptable results." Even effluent samples enriched with MS2 and R. terrigena, subjected to a two-phase evaluation, generated remarkably similar results. This consistency strongly suggests that no active antimicrobial agents are released into the treated water.

In short, silver proves to be a natural protector within Black Berkey® elements, guaranteeing flawless self-disinfection and water purification that meets the highest quality standards.
