Why do I need a Water Filter?

Water may seem as simple as 2 hydrogen atoms and 1 oxygen

atom (H20) but depending on where it’s come from, water can

contain all sorts of things, both good and bad.

In order to control the minerals and reduce unpleasant tastes/odours in your mains water, it is essential that some form of water treatment is utilised. Not only will this result in a better quality product - it will reduce clogging, scale build-up and corrosion, meaning equipment will operate more efficiently with less downtime and lower maintenance costs.

How does water affect my coffee?

In the increasingly refined world of speciality coffee, a lot of interest is given to how coffee beans from different parts of the world taste as well as how the roast, grind and brew affect the flavour. But there is one element that often gets overlooked when trying to achieve a genuinely great cup of coffee: water!

Besides the coffee beans you choose to brew with, water is the most important element that goes into any cup of coffee.

Did you know a coffee is made up of  98% water?

UK Water Hardness

Water’s hardness is determined by how many dissolved minerals it contains - the more calcium or magnesium your water contains, the harder it is. Though the UK Water Hardness Map (right) can give you an idea of how hard your water is; water type can still differ widely within a comparatively small geographical area. For example, some counties water type varies from town to town with pockets of both soft and hard water.

Due to the fact different locations can experience different levels of water hardness, we always test the water before installation of a Water Filter and ensure the settings are adjusted accordingly.

Water Filter Bypass Head

The Claris system's Filter Head contains a unique DuoBlend™ bypass valve which, unlike some other systems, is not affected by flow rate. The flexibility offered by the DuoBlend™ Filter Head not only makes the system suitable for many different types of coffee making equipment and vending machines but can also be adjusted to be suitable for different variations of water hardness.

Used in conjunction with a Claris Ultra, the DuoBlend™ Filter Head technology can help solve both scale and corrosion issues.

Pentair Everpure Claris

Ultra Water Filter

The Pentair Everpure Claris Ultra range offers world-first technology designed to help you achieve a balance between protecting equipment and producing the best quality coffee. It also maintains an acceptable acidity level, preventing corrosion to equipment whether installed in soft or hard water areas.

The Filter offers a 5 stage filtration process, which includes:

1. Pre-filtration

2. Carbonate hardness adjustment

3. Fine filtration

4. Highly effective carbon block

5. Solid membrane filter



To prevent the build-up of lime scale and permanent damage to your coffee or water machine we strongly advise the fitting of a Water Filter. Changing your Water Filter regularly not only ensures your beverages taste their best every time but also ensures your equipment will last longer.

We supply a Bypass Water Filter Head and visit your site regularly to change your Water Filter. You don’t need to worry about remembering when your Water Filter is due for its change; we will do that for you! We’ll get in contact a few weeks before it’s due to give you the heads up.
