1. Prefiltration
The expansion media removes coarse particles
2. Temporary hardness reduction
An ion exchanger reduces the temporary hardness content and prevents scale deposits
3. Activated carbon filtration
Substances that can impair taste and odor are eliminated
4. Fine filtration
Retains small particles

PURITY technology means:
• Optimal water quality
