Improve drink quality, reduce limescale build-up and protect your coffee equipment with this complete BRITA Purity C Quell ST C300 filter system bundle. The BRITA Purity C Quell ST range is designed for professional applications where water quality matters — including coffee, espresso, vending machines, combi steamers and ovens. It helps reduce carbonate hardness, limescale deposits and unwanted substances that can affect taste, aroma and equipment performance. This C300 bundle suits busy cafés, commercial coffee and espresso equipment, hospitality sites and vending. For smaller or lower-volume setups the C50 or C150 may be more cost-effective, while the highest-volume sites may prefer the C500 or C1100. The included 30% fixed bypass head allows part of the water to bypass the hardness-reduction stage, helping retain some mineral content while still reducing scale-forming hardness. This balance is particularly useful for coffee, where water affects taste, aroma and extraction consistency.
