BRITA PURITY C150 Café Water Filtration Set with 30% Bypass Head and FlowMeter

The BRITA café water filtration set is a complete system for connecting commercial coffee equipment to the mains water supply. It is designed for cafés, restaurants, hotels and other venues setting up a station with an espresso machine, a hot water boiler or a filter coffee machine. One set contains the PURITY C150 Quell ST filter, a head with 30% bypass and a FlowMeter, which are all the parts the installation needs to work.

Café water filtration set: three essential parts

A filter cartridge on its own is not enough to connect your equipment. You also need a head that connects the filter to the water line, and a flow meter that tracks how much water has been used. This set solves a common problem with a first purchase: the customer orders just the cartridge and only finds out during installation that there is no way to connect it or to tell when it needs replacing.

The set includes:

• BRITA PURITY C150 Quell ST filter: treats the water supplied to commercial equipment.
• BRITA PURITY C head with 30% bypass: holds the cartridge and sets the ratio of water flowing through the filter and past it. 3/8 inch male thread.
• BRITA FlowMeter 10-100 CU: counts the litres passing through the installation so you can track cartridge use.

Water filtration for commercial espresso machines and warranty

Manufacturers of commercial coffee equipment make their warranty conditional on proper water filtration. This applies to espresso machines, grinders with water dosing, hot water boilers and filter coffee machines. Without a filter you may lose warranty cover if a fault is caused by deposits or scale.

Scale builds up in boilers, pipes, valves and heating elements. Over time it restricts water flow and increases the risk of breakdown. That is why filtration is not an optional extra for a coffee station but part of installing the equipment correctly.

How do the bypass head and flow meter work?

The head holds the cartridge in the water line and lets you set the bypass. The bypass decides how much of the water passes through the cartridge and how much flows past it. The 30% version is a typical choice for espresso installations, but the right setting has to match the water in your particular venue.

The FlowMeter measures how much water has passed through the filter. This means you can replace the cartridge based on actual use rather than an approximate date. Replacing it too early adds unnecessary cost, while replacing it too late means scale can start building up in the equipment again.

How to choose the filter bypass setting

Measure the water hardness before starting up the installation. Water parameters vary by region, water source and even the building’s plumbing. The result tells you how to set the bypass and when to replace the cartridge.

There is no single filter capacity in litres that applies to every café. The actual capacity of the BRITA PURITY C150 Quell ST depends on the water hardness at your location and the bypass setting. That is why the flow meter is a practical operating tool, not an extra gadget.

One set for an espresso machine and a hot water boiler

The set can serve an espresso machine and a hot water boiler at the same time, as long as both are connected to one correctly built installation. This lets you monitor water use for the whole station with a single flow meter.

The PURITY C150 Quell ST cartridge is a consumable and needs regular replacement. The head and BRITA FlowMeter stay in the installation and can work with new cartridges for years. At the next change you only buy a new filter, without putting the whole system together again.
