Do I need to use filtered water?
Minerals in tap water will cause scale to build up inside your coffee machine. Scale can affect your machine’s performance and even damage your machine’s internals.
If you have poor quality tap water (eg, Adelaide) I recommend installing a water filtration system or using rainwater or bottled water.
If you have high quality tap water (eg, Melbourne) you can go ahead and use it. Most of my customers (9/10) use tap water. Of course, even with the best quality tap water you will still need to descale periodically.
