Brita Purity C1100 Quell ST Replacement Filter Cartridge

The Brita Purity C1100 Quell ST is a genuine replacement filter cartridge designed for use with the Purity C filter head in commercial kitchen water treatment systems. It filters the incoming water supply to reduce scale-forming minerals, heavy metals, and other impurities that affect both water quality and equipment longevity.

In busy commercial kitchens, water quality has a direct and measurable impact on equipment performance. Hard water causes limescale accumulation inside boilers, combi ovens, coffee machines, and water-fed appliances — gradually impairing heat transfer efficiency and shortening service life. By treating the water at source, the Purity C1100 helps reduce that build-up, keeping appliances running closer to their designed performance levels for longer.

Beyond equipment protection, filtered water also improves the consistency of hot beverages, soups, stocks, and any dish where water flavour carries through to the final product. Kitchens where taste consistency matters — hotels, contract catering, and high-volume food service operations — will notice a tangible difference in output quality.

• Reduces limescale build-up in water-fed commercial appliances
• Removes impurities including calcium, magnesium, lead, and copper
• Helps protect equipment investment and extend service intervals
• Supports consistent taste quality in beverages and water-based dishes
• Genuine Brita replacement — designed to fit and perform correctly in the Purity C system

This cartridge requires the Purity C Filter Head to operate. It is not compatible with other filter housings. Cartridge replacement frequency will depend on local water hardness and daily throughput volume — sites in harder water areas or with high daily water usage will typically need to replace cartridges more frequently. Brita's capacity guidance should be followed to ensure the system continues to filter effectively.

The C1100 is suited to medium-to-high-volume operations where a single filter point serves multiple appliances or a high-throughput single unit such as a combi oven or large boiler. For lower-volume sites, a smaller-capacity cartridge in the Purity C range may be more appropriate; for very high-demand installations, it is worth confirming the daily water volume against the cartridge's rated capacity before committing to a specification.

If you are unsure which Purity C cartridge size suits your site's water usage, or whether this system is the right choice for your appliances, we are happy to work through the options with you.
