Brita Purity C500 Finest filter cartridge

The BRITA Purity C500 is compatible with all professional coffee machines fitted with a BRITA Purity C-Series filter head. This industry-standard filter head system is fitted to most modern professional coffee machines: Lavazza (LB2210, LB2310, LB2610, LB4700 depending on options), Rancilio (Silvia Pro, Classe series), WMF (WMF 5000S, 9000S, Espresso), Franke (A400, A600, A800), Necta (Krea, Kanguro), Wega, Nuova Simonelli, Faema. Check for a Purity C head on the machine or in the manufacturer's documentation.

Not compatible with domestic / basic capsule machines (Nespresso, Dolce Gusto, Delta Q Mini Qool, Lavazza AMM/Blue LB300) — these machines use their own integrated filter system (see the Aqua Aroma Lavazza LB300 filter).

Two criteria determine the end of service life:

• Volume filtered: capacity of ~4 500 L at 10 °dH — the cartridge gradually becomes exhausted (saturated ion-exchange resin). Check using the water volume meter on the machine or filter system, if fitted.
• Maximum service life of 12 months: even if the volume has not been reached, replace at intervals of no more than 12 months for hygiene reasons (bacterial biofilm may develop on the activated carbon beyond this point).

Practical estimates of service life:

• Medium-sized office, 50 espressos/day — filtered water consumption of ~5 L/day → service life of ~2–3 years (limited to 12 months for hygiene reasons).
• Intensive use in cafés, hotels and restaurants, 200 espressos/day — consumption of ~20 L/day → service life of ~7–9 months depending on local water hardness.
• Restaurant / brasserie, 100 espressos/day — service life of ~12 months, annual replacement.

The BRITA Purity C-Series range uses the same technology across 5 increasing capacities — choose according to how intensively the machine is used and local water hardness:

• C50 — ~350 L, machines for intensive domestic or small-scale professional use.
• C150 — ~1 200 L, small cafés, hotels and restaurants or medium-sized offices. See our C150 model.
• C300 — ~2 700 L, medium-sized cafés, hotels and restaurants.
• C500 (this product) — ~4 500 L, intensive use in cafés, hotels and restaurants / large company offices.
• C1100 — ~11 000 L, industrial vending / very large cafés, hotels and restaurants / intensive hotel use.

The BRITA Purity C-Series filter head is universal — you can change capacity (C300 → C500 → C1100) without changing the head, just the cartridge. This is a major advantage for the operator.

Installation is simple and takes 5 minutes, with no tools required:

1. Turn off the water supply upstream of the machine.
2. Unscrew the used cartridge from the filter head (standard quarter-turn).
3. Insert the new C500 cartridge (turn a quarter-turn in the opposite direction until it clicks into place).
4. Turn the water supply back on; flush 2–3 L through the machine's outlet (using the hot water button or running an espresso cycle without coffee) to remove resin fines from the initial fill.
5. Reset the machine's water volume meter, if fitted (maintenance menu).

If the machine's flow rate drops after installation or you detect a leak at the head, contact Cafemalin after-sales support.

Three main reasons:

1. Protect the machine — limescale is the biggest killer of professional coffee machines. Without a filter, limescale quickly builds up in the boiler and internal circuits (especially in very hard water areas): reduced performance, repeated breakdowns and a manufacturer's warranty often conditional on upstream filtration.
2. Preserve the taste of coffee — coffee is 98% water: its quality directly determines the taste in the cup. Chlorine + excessive dissolved minerals = metallic or chlorine notes, less dense crema and muted fruity aromas.
3. Comply with HACCP standards — in cafés, hotels, restaurants and offices open to the public, water quality traceability is required during HACCP audits. A dated and monitored BRITA filter serves as documentary evidence.

Yes — BRITA is the world's No. 1 in water filtration for food and drink. Founded in 1966 in Taunusstein (Germany) by Heinz Hankammer, the brand invented the activated carbon water filter jug for consumers, then developed a professional B2B range (Purity C, Purity Fresh, Purity Steam) for coffee machines, hot water dispensers, steam ovens and ice machines. BRITA supplies most major professional coffee machine manufacturers (Lavazza, WMF, Franke, Rancilio, Nuova Simonelli, etc.) through filtration partnership agreements. It is the default choice for café, hotel and restaurant operators or office purchasing managers who want to safeguard the quality in the cup and the machine's longevity.
