Peak Water Replacement Filter Cartridges If you look under the espresso machine at your local café, you’ll likely find a complex filtration system using line pressure to force water through chambers of resin and carbon. These systems allow baristas to adjust water hardness via a bypass valve, tailoring water chemistry to their needs. While effective, they’re bulky, expensive, and impractical for home use. Peak Water’s revolutionary countertop solution changes that.
