- Prevent costly machine repairs by reducing scale and corrosion
- Achieve optimal water balance for rich coffee taste and aroma
- Filter out chlorine, sediment, and unwanted tastes
- Match your filter to local water types (soft, hard, salty, or gypsum)
- Suitable options for Breville, La Marzocco, and commercial machines
Why Water Quality Matters for Coffee
Espresso machines are precision tools, and unbalanced water can lead to serious issues like scale build-up, corrosion, and chalky or under-extracted coffee. Australian tap water varies widely- what works in Melbourne may not work in Perth. That's why filtration isn't just about the brand of your machine; it's also about the quality of the filtration system. It’s about treating the water you have to reach the right balance of chlorides, carbon hardness, and TDS (Total Dissolved Solids).
Which Water Filter Do I Need?
Choosing the right filter starts with understanding your local water:
- Soft water (e.g. Melbourne): May need remineralisation to improve extraction and taste.
- Hard or scale-prone water (e.g. Perth): Choose filters that reduce carbonate hardness and prevent build-up.
- Chloride-heavy water (e.g. coastal areas): Avoid corrosion with a balanced filter that reduces salt content.
Get your water tested (local pool shops or test kits available) and choose based on your region's needs, not just your machine.
Featured Filter Technologies
- Carbon Filtration: Removes chlorine, odours, and fine sediment. Good for relatively clean water like Sydney's. Everpure 4FC-S is a top pick.
- Ion Exchange (Softening): Balances carbon hardness and protects against chlorides. Ideal for harsher water. Try the Claris Ultra 250.
- Multi-Stage Filtration: Combines pre-filtration, carbonate hardness reduction, activated carbon, and fine particle filtering. The Brita Purity C Series is a leading choice for cafés, vending machines, and commercial kitchens.
- Reverse Osmosis: Strips out nearly all impurities—perfect for full control. Requires remineralisation for coffee use. Recommended in areas with extreme water issues.

Frequently Asked Questions
Do I need a water filter for my coffee machine?
Yes. Even high-end machines are vulnerable to scale and corrosion from unfiltered water. A proper filter protects your investment and improves coffee taste.
How do I know what water filter I need?
Start by testing your water's TDS and mineral content. Choose based on your local water type, not your machine. Use carbon for chlorine removal, softeners for hardness reduction, and reverse osmosis (RO) for complete control.
Can I use a BWT jug for my espresso machine?
BWT jugs are a good starting point, especially if you're using an entry-level espresso machine like a Breville. They help reduce chlorine, odours, and moderate hardness, improving the taste of your coffee and protecting your machine from limescale. For even better performance, especially in machines with water tanks, consider BWT Bestsave filter pouches. These drop directly into the tank, add magnesium for better flavour, and protect against scale. For very hard or high-TDS water, you may need a more advanced filter setup like an in-line or reverse osmosis system.
What’s the best water TDS for espresso?
A 90-110 ppm TDS is ideal for balanced extraction and taste. Too low, and the coffee lacks body; too high, and it becomes chalky, potentially damaging your machine.
How often should I replace my water filter cartridge?
It depends on water quality and volume used. Using a flow meter provides a scientific method for tracking usage. Otherwise, replace every 6-12 months or as recommended by the filter brand.
