Accessories — water and taste filtration for coffee machines

Coffee machine filter cartridges

Q: Why install a water filter on my coffee machine?

A limescale-resistant water filter for professional coffee machines offers four major benefits: Extends the machine's lifespan — limescale buildup is the leading cause of failure in professional coffee machines. A Brita Purity filter typically adds 3 to 5 years of longevity. Improves coffee taste — filtered water that is neutral in limescale and pH balanced better reveals roasted aromas and allows for better extraction. Reduces maintenance — fewer descalings, fewer technical interventions, fewer downtimes in HoReCa establishments. Cost-effective — a C150 cartridge (~€60, ~6-12 months) costs less than a single service call for descaling (~€150-€300).

Q: What is the difference between Brita Purity C150 and C500?

The two Brita Purity cartridges are designed for different volumes and uses: Brita Purity C150 Quell ST (~€60) — medium capacity cartridge. Filtration capacity: 3,000 to 5,000 liters (~500 to 800 espresso cups/day for 6 to 12 months). Ideal for: bars, brasseries, medium-volume restaurants, offices with professional machines. Quell ST formula: balanced water for coffee (retains limescale, preserves essential minerals for taste). Brita Purity C500 Finest (~€135) — high capacity cartridge. Capacity: 10,000 to 20,000 liters (~1,500 to 3,000 espresso cups/day for 12 to 24 months). Ideal for: high-volume hotel cafes, restaurants, catering, industrial automatic coffee machines. Finest formula: finer filtration, optimal results for specialty espresso. Cost per cup: C150 ~€0.015/cup · C500 ~€0.010/cup. The C500 becomes more economical from ~50-70 cups/day.

Q: When should I replace my Brita Purity cartridge?

The lifespan of a Brita Purity cartridge depends on the volume filtered and the water hardness. Technical guidelines: C150 Quell ST — replace every 3,000 to 5,000 liters filtered or every 6 to 12 months (whichever is shorter). C500 Finest — replace every 10,000 to 20,000 liters filtered or every 12 to 24 months. In practice, most high-end professional espresso machines include a filter volume counter or a filter wear indicator. Consult your machine's manual or activate the monitoring feature using a Brita filter head with an integrated counter.

Q: Which machines is the Lavazza Aqua Aroma Crema filter compatible with?

The Lavazza Aqua Aroma Crema Filter (~€16) is compatible with the following Lavazza Blue professional machines: Lavazza Blue LB300 Classy Mini — compact Blue capsule machine; Lavazza Blue LB900 — medium Blue sized office/small restaurant capsule machine; Lavazza Blue LB1050 — high-capacity professional/vendor Blue machine. It is installed in the machine's water tank and improves the taste of your espresso (denser crema, preserved aroma). Please note: this filter is not a professional limescale inhibitor. For complete limescale protection, add a Brita Purity cartridge upstream if your water is hard (> 25°TH).

Q: How can I tell if the water in my area is hard?

Water hardness is measured in °TH (French degrees of hardness). Reference points: Soft — 0 to 15 °TH · Western France, Brittany, Massif Central. Filter optional. Medium hard — 15 to 25 °TH · Most regions. Filter recommended for professional machines. Hard — 25 to 35 °TH · Northeast, Île-de-France, Paris region, Paris Basin. Filter required for professional machines. Very hard — > 35 °TH · Some municipalities in the Southeast and North. Brita C500 Finest filter recommended. Consult the water quality report for your municipality on the website of your regional health agency (ARS) or on solidarites-sante.gouv.fr.

Q: Delivery and return of filter cartridges?

Two types of filters are essential for properly equipping a professional or high-end automatic coffee machine. Each serves a different technical purpose:

Anti-limescale water filters — Brita Purity. Founded in 1966 in Germany, Brita is the global leader in professional water filtration. The Purity range covers Ho.Re.Ca. and industrial machines: Purity C150 Quell ST (~€60) — medium-capacity cartridge for medium-volume bar/restaurant coffee machines; Purity C500 Finest (~€135) — high-capacity cartridge for high-volume professional coffee machines, hotel cafes, and other establishments. These filters eliminate limescale, reduce heavy metals, balance the water's pH, and extend the life of your espresso machine by several years.
Coffee quality filters — Lavazza Aqua Aroma Crema . Specific organolithic filter Lavazza Blue (~€16) — compatible with LB300 Classy Mini , LB900 , and LB1050 machines . This filter is installed in the machine's water tank and improves the crema and aroma of the extracted coffee. It does not replace a professional anti-scale filter such as a Brita — it is a flavor-enhancing accessory .

The choice of filter depends on the type of machine and the water hardness in your area:

Very hard water (> 25 °TH) — professional machines: Brita Purity C150 filter required. High volume (> 100 cups/day): Brita C500 Finest.
machine Blue LB300/LB900/LB1050 — Aqua Aroma Crema recommended as an accessory (improves crema). Does not replace a limescale inhibitor if the water is very hard.
High-end espresso machines with grinders — Brita Purity C150 (medium use) or C500 (heavy use Ho.Re.Ca.).

The average lifespan of a Brita Purity C150 cartridge is approximately 3,000 to 5,000 liters filtered (6 to 12 months depending on volume), and up to 10,000 to 20,000 liters for the C500 Finest (12 to 24 months). The Lavazza Aqua Aroma Crema filter should be replaced approximately every 2 months, depending on usage.
