Jura Water Filters: What They Are, Why You Need One and Where to Buy Them

Your Guide to Jura and Jura Claris Coffee Machine Water Filter Replacements

If you’ve got a Jura bean-to-cup coffee machine, chances are you care about good coffee. But here’s the deal: great coffee isn’t just about beans or machines – it starts with clean, high-quality water. That’s where the Jura Claris water filter comes in.

In this no-nonsense guide, we’ll walk you through what Jura filters do, which ones you need, how often to change them, how they affect your machine and your coffee – and most importantly, how to get genuine filters without paying through the nose.

Let’s get stuck in.

What Is a Jura Claris Water Filter?

A Jura Claris water filter is a cartridge that sits inside your Jura coffee machine’s water tank. Its job is simple but essential: remove impurities from tap water before it hits your beans.

Why does that matter? Because better water = better coffee. And more importantly, it protects your machine from limescale, extending its life and cutting down on descaling.

Why You Actually Need One (No, It’s Not Optional)

We get it – filters can feel like one more thing to remember. But if you’re thinking of skipping them, here’s why that’s a terrible idea:

  • Limescale is a killer. It builds up inside your machine, clogs pipes, and wrecks your heater.

  • Unfiltered tap water affects taste. Chlorine and metals = dull, flat coffee.

  • Using a Claris filter means fewer descaling cycles, which saves time and hassle.

  • Jura machines are calibrated to work best with the filter in place – so skipping it? Not worth the risk.

Think of the Claris filter as cheap insurance for your pricey machine.

Which Jura Water Filter Do I Need?

Here’s the fun part: not all Jura filters are the same. The one you need depends on your machine model and whether it uses the old blue filters, the newer white Smart filters, or the Smart+ upgrade.

🔹 Jura Claris Blue

  • Older machines like the Impressa range.

  • Push-fit design.

  • Still available and supported.

🔹 Jura Claris White

  • Predecessor to the Smart filters.

  • Used in select older models.

🔹 Jura Claris Smart

  • Used in newer machines with Intelligent Water System (I.W.S.) tech.

  • Machine automatically detects the filter and tracks usage.

  • You’ll see “Smart filter recognised” on screen.

🔹 Jura Claris Smart+

  • The latest version with an upgraded membrane and added benefits.

  • Backwards-compatible with Smart machines.

  • Better filtration, longer life.

✅ Top Tip: If your machine uses Claris Smart, it can also use Smart+.

Not sure which one your machine needs? The product listings on our filter collection page make it easy. Just match the model.

How Often Should I Replace My Jura Water Filter?

This is a big one. According to Jura, the filter should be changed after 50 litres or 2 months, whichever comes first.

But here’s the reality:

  • If you make 4–6 coffees a day, expect it to last around 6–8 weeks.

  • Some machines will alert you automatically when it’s time to change.

  • Ignoring the alert just delays the inevitable – and risks scale damage.

📅 Set a reminder, or better yet, buy a few at once and stash them in the cupboard.

What Happens If You Don’t Change the Filter?

Short version? Nothing good.

  • Water quality drops = worse-tasting coffee.

  • Scale builds up = reduced performance and lifespan.

  • If the filter clogs, your machine may stop brewing altogether.

You might save a few quid now, but you’ll pay it back in repairs, descaling, or a new machine later. Not worth the gamble.

Are Jura Claris Filters Reusable or Refillable?

No – and don’t be tempted by DIY hacks.

Each filter cartridge is single-use. Trying to refill or clean them defeats the point: once it’s done filtering, it’s done.

Some third-party refill kits are floating around online, but we don’t recommend them – they can damage your machine or give inconsistent results. Jura machines are fussy for a reason: they’re built for performance, and cheaping out on filters just messes with that.

Where Can I Buy Genuine Jura Water Filters in the UK?

Great question – because there’s a lot of knock-offs out there. If the price seems too good to be true… it probably is.

Can You Use a Jura Machine Without a Filter?

Technically yes. Practically? Not a great idea.

If you remove the filter:

  • You’ll need to descale the machine regularly – manually.

  • Your machine may show alerts or warnings.

  • You could void part of your warranty if damage occurs from scale buildup.

And let’s be honest – if you spent hundreds (or thousands) on a premium Jura, why risk it to save a few quid on filters?

How Do You Install a Jura Water Filter?

It’s super simple – takes under a minute.

  1. Remove the water tank.

  2. Insert the filter into the designated holder (Smart filters snap in, Blue push-fit).

  3. Fill the tank with cold water.

  4. Place the tank back.

  5. Your machine will detect the filter and ask you to confirm activation (on Smart models).

  6. Run the filter rinsing programme when prompted.

That’s it. Your machine’s protected, your water’s clean, and your coffee’s going to taste brilliant.

Do Jura Claris Filters Fit Other Coffee Machines?

Not really.

They’re specially designed for Jura machines. Other brands use different connectors, sizes, or filter materials – so don’t try to force a fit.

If you’ve got a bean-to-cup from another brand, check our full water filter collection – we’ve got options for most major models.

How Can I Tell If My Jura Filter Needs Replacing?

Keep an eye out for these signs:

  • You get a "Replace filter" or "Filter expired" message.

  • Coffee starts tasting dull or off.

  • Brew times slow down.

  • You notice chalky residue in the water tank.

And of course, if it’s been more than 2 months, just swap it.
