The PURE UPSTREAM Companion Series Advantage
Purified Water That Stays Pure in Storage
Unlike many water treatment methods, water purified with the Companion Series can be safely stored for extended periods.
​
Because silver ions remain in the treated water, they continue providing antimicrobial protection during storage, helping protect against bacterial and viral recontamination. Purify today, and your water is still protected when you need it most.
