Abstract
In one example, a filter cartridge includes a housing having a fluid entry port and a fluid exit port, and the housing has a chamber in fluid communication with the fluid entry port and the fluid exit port. A first medium is disposed within the chamber and includes a material that serves to change the pH of a fluid passing through the first medium. A filtration medium is disposed in the chamber downstream of the first medium and arranged to receive effluent of the first medium. The filtration medium includes a material configured to remove a metal from a fluid passing through the filtration medium.
