BRITA Purity C Quell ST C300 Filter System - 30% Bypass with Install Kit

Protect your coffee machine, improve drink quality and reduce limescale build-up with this complete BRITA Purity C Quell ST C300 filter system bundle.

Designed for professional coffee, espresso and vending equipment, the BRITA Purity C Quell ST range reduces carbonate hardness, chlorine and other unwanted substances that can affect taste, aroma and machine performance. This makes it an ideal choice for cafés, offices, hospitality sites and anyone using commercial coffee equipment where consistent water quality matters.

This bundle includes the BRITA Purity C Quell ST C300 cartridge, a 30% fixed bypass filter head, John Guest push-fit fittings and 3/8" tubing, giving you the key components needed for a clean and professional installation.

The 30% bypass head allows a controlled portion of water to bypass the decarbonisation process, helping maintain a balanced mineral content while still reducing scale-forming hardness. This is particularly useful for coffee machines, where water quality plays a major role in flavour, extraction consistency and equipment protection.
