Best Espresso Machine Water Filter — Review & Guide! 

Water, Water, Water! Something you can’t live, cook or brew your coffee without.

Growing up in the upstate, I had the privilege to drink tasty tap water. My family didn’t have to buy bottled or filtered water like most relatives did. And never have I ever in my youth given a second thought about it.

But now that I live in an apartment in the city, the privilege is simply not there. Instead, I have to drink filtered water. The reason is simple—the tap water is bland.

The flavour and build-up contribute to the taste of water. So when your tap water’s flavour is bland, it’s obvious you don’t want to have it.

Then comes the build-up (usually seen around showerheads and sinks), which really kills the vibe of your espresso or coffee machines, and you get bland coffee to start your day.

So, what can you do about it?

Of course, we all know the importance of a good cup of coffee in the morning. And today, I will review the top 5 best Espresso machine water filters that I have tried and tested in my apartment. 

Why Should I Use Filtered Water in my Coffee Machine?

We all have learned about scale and water hardness in our science classes. The scale forms a layer of calcium crust around the inside of your machine. The build-up keeps forming and forming and destroys the interior of the machine.

For the boiler, the coating of calcium also restraints water heating. As a result, the coffee you get won’t be warm, resulting in suboptimal coffee temperature that usually is not convenient.

Wait! The list just doesn’t end there. If you don’t descale the coat from the inside of your machine, they can break off literally like asteroids. And these tiny little asteroids will trundle through your machine and will block passageways plug small holes and openings.

Not using filtered water will destroy your investment in a coffee machine, and I hope you don’t want that. However, that is why you should use filtered water in your coffee machine.

How Does Water Quality Affect the Flavour of your Coffee

As I have said before, if your water’s taste is stale, that very staleness will be conveyed to anything your brew or cook. I have worked as a barista before, so trust me. I know all about brewing coffee and espresso.

The flavour of your coffee/espresso depends on many factors like freshness, temperature, roast profile, consistency of fines, grinds, and of course, the universal solvent—water. All of it impacts the flavour of your coffee directly.

Complexly, if your water is vessel to any minerals or contaminants, it will thrust the taste and impact the extraction of your espresso/coffee.

Let’s say that you have your water softened enough but it still may contain other contaminants that will go directly into your coffee cup.

So, no matter how much of a professional coffee brewer you are, the taste of your coffee will always be determined by the quality of your water.

Can I Use Distilled or Reverse Osmosis Water for Making Coffee?

Hold your horses, man! Don’t do it. If you are not a scientific person, it may lead you to think, “Why the hell would I need minerals in my coffee?”

It seems logical to use reverse osmosis or distilled water in your machine to fix the issue of the water scale. As a matter of fact, it may be really tempting, but it’s the worst of all things that you can do. Why?

The water is a solvent, and it needs minerals to carry the flavour of your coffee/espresso. And sometimes, the machine needs to detect the minerals in water to work.

The water that lacks minerals can leach metal from your plumbing and boiler, and it will corrode the machine. Yes, it definitely will.

Also, keep in mind that mineral-deficient water will lead to over extraction of coffee. I hope you understand why it is not a good choice to use distilled/reverse osmosis water to make coffee.

What Kind of Water is Best for Espresso Machines?

What Kind of Water is Best for Espresso Machines?

The fact is crystal clear that your water has a great impact on the taste of your coffee flavour. But like machines, there are different kinds of water too. So, which one is the best? Let’s discuss!

Filtered Water: This is the best option to choose as it is more convenient, best for your health and environment, and budget-friendly. It doesn’t affect your coffee flavour in any way, so, in my opinion, it is the best option.

Tap Water: The easiest solution of all. But ever heard of the phrase, “With great ease, comes greater sacrifice”? Yes, that’s right, folks. Using tap water can make your coffee taste absurd, as mentioned before.

Bottled Water: If you want to skip the hassle of buying and installing a water filtration system, using bottled water is the way to go. However, we still do not recommend this as this creates more plastic wastes and destroys our beloved planet. Furthermore, it should be noted that this quite costly too.

What kind of Water does Breville use?

The answer is pretty straightforward. The manual of Breville espresso machine water filter quotes, “DO NOT use highly filtered, distilled, or demineralised water in this machine. This may affect the taste of coffee and how the machine operates.” This quote gives the basic understanding of the kind of water the machine uses.
