Whole House Water Filter Cartridge Replacement Guide

Know when and why to replace PP sediment and CTO carbon cartridges in whole-house water filter systems.

Why cartridges matter

Sediment cartridges capture dirt, sand, rust and silt. Carbon cartridges help improve taste and odour by reducing chlorine and organic compounds.

When to replace

Replace cartridges when pressure drops, taste changes, flow reduces or the cartridge reaches the service interval recommended for your water quality and usage.

Keep spares ready

Whole-house system owners should keep PP sediment and CTO carbon cartridges available so maintenance is quick and the system keeps protecting plumbing and appliances.
