Category: Coffee Filtration
Pentair
Your filtration system is only as good as the cartridge currently in it.
The Pentair CTO-20 Replacement Cartridge restores your filtration system to full performance — maintaining the water quality your equipment and your coffee depend on.
The Details
System Performance Restoration
Replaces exhausted media to restore full filtration capacity — scale, chlorine, and TDS reduction back to original specification.
Genuine Replacement Media
Manufactured to the system's original specifications. Same performance from first use to rated capacity — not a compatible generic.
Equipment Protection
Continuous scale and chlorine protection for espresso machines, brewers, and ice equipment throughout the cartridge life.
Scheduled Replacement
Replace on the rated capacity schedule — a fresh cartridge is the routine step that keeps water quality from drifting.
