Your filtration system is only as good as the cartridge currently in it.

The Pentair CTO-10 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.

Penelope T. ★★★★★

My tap water tastes noticeably cleaner and my Keurig hasn't had any scale buildup since I swapped this cartridge in. The simple twist-on design made installation a breeze.

Evelyn K. ★★★★★

The water pressure in my espresso machine has been much more consistent since swapping to this filter cartridge. It's clearly doing its job with the sediment and chlorine removal, making each cup noticeably cleaner.

Scarlett I. ★★★★★

I’ve been running this CTO-10 cartridge for a few weeks now, and my coffee maker’s water flow has noticeably improved compared to the old one. The fit was snug but straightforward to install, and my morning brew tastes cleaner. Definitely worth swapping out for consistent water quality.
