About this accessory
The CO-SB150-K provides the perfect balance between protecting espresso equipment and the ideal water quality for espresso brewing. The role of water when creating coffee is to extract flavour compounds from the bean. Ideally, brewing coffee collects appetising compounds and leaves behind the unpleasant ones. Calcium, magnesium and carbonate play an important role in enhancing and muting flavours derived from coffee grounds. Unfortunately, when heated calcium and carbonate create limescale, which is bad news for the lifespan and performance of any coffee machine. Balance+ Technology was brought about from the desire to maintain flavour-enhancing minerals in the water so that a balanced flavour is achieved, whilst still protecting equipment from limescale.

What other customers have actually taken home in the last little while — straight from our order book, not a curated list.
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.

Tell us when suits and what else you are weighing up, and we will confirm a time to see them in the showroom.
Talk to a specialist
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.
