Jura CLARIS Water Filter: Which Cartridge Your Machine Takes
Jura machines take one of four CLARIS cartridges: Blue (71312), Blue+ (24231), Smart (71794) or Smart+ (24232). They are not interchangeable. Smart cartridges carry an RFID chip the machine reads; Blue does not. Check which your model's manual names before ordering - the wrong one either will not seat or will not be recognised.
Also sold as: 60209 60468
Does it fit your machine?
Match your model number exactly — the code on the rating label, not the name on the front of the machine.
| Model | Notes |
|---|---|
| CLARIS Smart (71794) | Grey. RFID chip. Machines with the Smart filter system - most current bean-to-cup models. |
| CLARIS Smart+ (24232) | Successor to Smart, 6-pack. Same fitment as Smart. |
| CLARIS Blue (71312) | Blue. No chip. Older ENA, IMPRESSA and Micro ranges. |
| CLARIS Blue+ (24231) | Successor to Blue, 3-pack. Same fitment as Blue. |
| CLARIS White | Legacy cartridge on early IMPRESSA. Superseded - check the manual before ordering. |

OEM or aftermarket?
Jura sells four CLARIS cartridges and they look similar enough that people order the wrong one regularly. The difference that matters is not the colour on the box, it is whether your machine expects to read a chip.
The four cartridges
CLARIS Smart (71794) and its successor Smart+ (24232) carry an RFID chip. The machine reads it when you seat the cartridge and logs the change itself. CLARIS Blue (71312) and Blue+ (24231) have no chip; on those machines you tell the machine through the menu that you have changed the filter. CLARIS White is the legacy cartridge from the early IMPRESSA era and has largely been superseded.
They are not cross-compatible. A Blue cartridge in a Smart machine is the common mistake, and the failure is quiet rather than obvious: the filter physically sits there doing its job, but the machine never registers a change, so it keeps counting down against the old cartridge and eventually starts asking for a descale you should not need.
Why Jura treats the filter as descaling
Jura’s own position is that a correctly fitted CLARIS filter removes the need to descale, because the cartridge sits in the water tank and treats the water on every single brew rather than after the fact. That claim comes with a condition attached: it only holds while the filter is current and the machine’s water hardness setting matches your actual supply.
This is why the hardness setting is worth getting right rather than leaving at the factory value. Set it harder than your water actually is and the machine will schedule filter changes and maintenance far more often than needed, which is expensive at fifty dollars a three-pack.
Getting the interval right
Jura counts filter life in litres filtered, not days, so there is no fixed calendar figure. The machine will tell you when it is due. If you are getting noticeably less life than you expect, check the hardness setting before assuming the cartridges are faulty.
One habit worth building: change the cartridge when the machine asks, not when you next remember. The cost of a late change is not just worse-tasting coffee, it is scale in a boiler that is expensive to deal with on a bean-to-cup machine.
Cartridges that fit
Buy the cartridge your manual names. Multi-packs are the sensible unit here because the interval is short enough that a single cartridge is false economy.
If the filter is not the problem
A Jura that has been run without a filter for a long stretch may need a genuine descale before a new cartridge is worth fitting – the filter prevents scale, it does not remove what is already there. If your machine is asking for maintenance for a different reason, the error and light guides cover what each alert actually means, and the super-automatic section collects the rest of the bean-to-cup maintenance.

Questions about this part
How do I know if my Jura takes Blue or Smart?
The machine's manual names the cartridge, and the filter bay itself is the giveaway: Smart cartridges have an RFID chip that the machine reads when you seat them, so a Smart machine will confirm the filter on screen. A Blue machine has no chip and asks you to confirm the change through the menu instead.
Can I use a Blue cartridge in a machine that wants Smart?
No. Beyond the physical fit, a Smart machine expects to read the chip. Without it the machine will not register that a new filter is in, so it keeps counting toward the old filter's expiry and will nag you to descale.
How often does a CLARIS cartridge need changing?
Jura counts it by litres filtered rather than by calendar, and the machine tells you when it is due. In practice most households land somewhere around two months. If you are getting far less than that, the water hardness setting is probably too high.
Does a CLARIS filter really replace descaling?
Jura's position is that with the filter fitted and the machine set to the right water hardness, descaling is not needed. That holds only while the filter is current. Skip a change or two and scale starts building again in the boiler.
Why is my machine still asking to descale with a new filter in?
Two usual causes: the filter change was never confirmed in the menu, so the machine does not know it happened; or the water hardness is set higher than your actual supply, which makes the machine schedule maintenance far too often.
