In our previous post we established the “why” in terms of having a water filter for your coffee machine, let’s now explore what features/types of filtration are important in a water filter for espresso.
The main thing you want to look for is sediment filtration, followed by lime filtration and ideally, a chlorine filter (though this is exclusively for taste). Pay attention to the cost of replacement filters in relation to the capacity of the filter before it needs replacing.
It’s important to replace your filters on time or when at capacity to prevent sediment from entering your espresso machine.
With a little foresight and prevention, you can keep your espresso machine performing in peak condition for many many years to come.
