NOT SURE WHICH FILTER IS RIGHT FOR YOU?

WHY YOUR COFFEE MACHINE NEEDS A WATER FILTER

Even the best tap water may contain dissolved substances which might make it taste or smell weird – which in turn affects the taste of your coffee. This starts with hard water but also includes chlorine, iron or even heavy metals. With a reliable water filter for your coffee maker, you’ll dramatically improve the taste of your daily pick-me-up. 

They’re especially useful for bean-to-cup and espresso machines. Hard water doesn’t just ruin taste, it can also lead to limescale, which might shorten the lifespan of your coffee machine. 

With Ecosoft filter systems, you can brew your coffee with pure, filtered water – free from unwanted notes, and full of natural flavour. Even better: our reverse osmosis systems don’t just remove harmful substances, they also re-mineralise your water with essential elements like magnesium and calcium. Magnesium in particular helps create a stable, rich crema bursting with flavour. Perfect for anyone who truly appreciates great coffee.

FAQ: Water for coffee – your questions answered

  • Filtered water is free from any unwanted substances and lets the bean’s true flavour shine. That means more aroma, more depth, and more enjoyment in every cup. 

  • Yes – but we recommend using a water filter for your coffee machine that also re-mineralises the water. Not all minerals are bad – elements like magnesium and calcium actually play a vital role in perfecting your coffee’s flavour. 

  • That depends on the system you’re using. Some filters last 1 month, others up to 6. The CROSS 90 Balance even has an LED display that lets you know exactly when it’s time for a change. The RObust Mini is also easy to maintain, with user-friendly cartridge replacement designed for regular home use. 

  • That depends on your situation. If you’re looking for a flexible, affordable solution, we recommend the Slim Jug. If you're looking for long-term high performance, go with the CROSS 90 Balance or the RObust Mini — the latter is specially designed for coffee applications and delivers outstanding results for home use. 

  • Magnesium plays a key role in coffee flavour. It helps extract aromas evenly and supports a well-rounded taste.  

    Our CROSS 90 Balance system re-mineralises the water with magnesium and calcium after filtering – giving your coffee more depth, more crema and a perfectly balanced flavour.  

  • There are many things that can affect the taste of your coffee – and water contains many of the deciding factors: 
     

    • Chlorine: Masks subtle aromas and creates a sharp smell
    • Hardness: Overpowers flavour and flattens the crema
    • Heavy metals: Disturb the mouthfeel and strain your machine
    • Micro-contaminants: Disrupt extraction balance 


    An Ecosoft water filter for your coffee machine solves these problems and ensures consistent water quality – and consistent coffee flavour. 

  • It’s often not the machine or the beans – it’s the water. Hard or chlorinated water affects extraction, which makes the crema look flat or patchy. Using a water filter to purify your water before brewing your coffee can help with that.

What our customers say about Ecosoft water filters for coffee machines

My barista-grade coffee maker is my pride and joy. Now, with the CROSS 90 Balance, I’ve finally got the perfect water for it, too. No more limescale, less maintenance, and best of all: my espresso tastes just like in Italy.

I use a bean-to-cup machine and always wondered why coffee at home never tasted as good as in a café. The Ecosoft PURE Balance changed that completely – every cup is a delight now.

I didn’t want a built-in solution, so I went for the Slim filter jug. It looks great, fits in the fridge, and my filter coffee tastes miles better.
