• Applications: Best for high-traffic cafés, large restaurants, and foodservice operations that require constant water filtration.
• Pros:
  • High-capacity filtration, reducing the need for frequent replacements.
  • Comprehensive water purification for demanding environments.
  • Excellent limescale protection for extended machine life.
• Cons:
  • More expensive and bulkier compared to standard models.
  • Not necessary for small operations with lower water usage.

6. BWT Bestprotect

• Filtration Technology: Dual-action ion exchange and activated carbon filtration.
• Features:
  • Provides simultaneous protection against limescale and corrosion.
  • Adjusts the pH balance of the water to protect machines from acidic conditions.
  • High-capacity design for commercial use.
  • Available in different sizes.
• Applications: Ideal for areas with aggressive water chemistry, balancing the pH and preventing scaling and corrosion in espresso machines and combi ovens.
• Pros:
  • Exceptional protection for both scaling and corrosive water conditions.

  • Suitable for high-volume, high-mineral-content areas.
• Cons:
  • Over-engineered for areas without water chemistry issues.

7. BWT Besttaste

Purpose: Designed for locations where taste improvement is the primary concern rather than limescale reduction, such as in soft water areas or for cold beverage applications.

• Filtration Technology: Activated carbon with taste optimization.
• Features:
  • Primarily focuses on removing chlorine, organic substances, and off-flavors.
  • Retains minerals for optimal beverage taste without removing hardness.
  • Ideal for enhancing the taste of tap water and cold beverages.
  • Available in multiple sizes.
