Brita Purity Quell ST 450 Pro Filter Cartridge Refill

These cartridges are specially manufactured to fit coffee machines and automatic dispensers.

Water quality issues are responsible for 60% of breakdowns on espresso machines.

With thePurity 450 Quell STyou will benefit from an average filtration of4200Lfor coffee machines, i.e. 263kg of coffee/year (capacity calculated with a hardness of 10°Kh, national average value, and a bypass set at 40%).
It is recommended to analyze your water hardness beforehand to identify the appropriate cartridge model. For a complete installation, the cartridge requires a Brita Quell ST connection head (available separately) as well as two compatible fittings. A flow meter will allow finer consumption monitoring.

The benefits of filtered water:

For your coffee:
• Optimization of aroma extraction
• More stable and persistent crema
• Stable brewing temperature (limescale creates thermal insulation)

For your machine:
• Reduction of limescale buildup
• Decrease in unexpected breakdowns
• Reduction of service interruptions
• Control of costs related to travel, labor and spare parts

1. Pre-filtration
   Retains large-sized particles
2. Carbonate hardness reduction
   An ion exchange resin reduces carbonate hardness concentration and prevents limescale deposit formation.
3. Activated carbon filtration
   Removes the majority of compounds affecting taste and odor.
4. Fine filtration
   Captures particles up to 10 µm in diameter.

Note that no water treatment solution applies uniformly: each geographical area has specific water characteristics. The actual filtration capacity can thus fluctuate according to regions.
