About this accessory
The Bombora Scale Stopper cartridge is a replacement filter cartridge built to protect your espresso machine from scale. Scale is the mineral build-up hard water leaves behind, and over time it clogs boilers, valves and lines, which is exactly the kind of damage this cartridge is designed to hold back.
Fitting a fresh cartridge keeps your water treatment doing its job. Cleaner, scale-controlled water means fewer mineral deposits inside the machine and better-tasting coffee in the cup, since off-flavours from untreated water don’t carry through.
Swap in a new cartridge before scale becomes a problem. Order yours now.

Before you buy
Built for 58 mm portafilters — the size used by essentially every prosumer machine we sell, including Bezzera, ECM, Lelit, Profitec, Quick Mill and Rocket. If you're on a 51 mm or 54 mm machine, talk to us first.
Tell us the machine you own and we'll confirm the fit before you order. It takes one phone call and saves a return. Call 1300 551 626 →
Dispatched from our Brisbane warehouse, usually within 1–2 business days. Pickup from the Woolloongabba showroom is available if you'd rather collect.

Why buy it here
We don't stock accessories because a distributor offered them. Our technicians use this gear on the bench every day — so if it's here, it's because it holds up and it actually fits the machines we sell.
Goes well with
The grinder matters as much as the machine — here's what we'd pair with it.

We would rather spend ten minutes helping you land on the right machine than process a return later. Call us, start a chat, email, or send this and we'll come back to you.
