Should every filter cartridge be replaced after the same number of months? No single interval applies to all cartridges.
Start with the manufacturer's instructions, then consider feedwater, water use, differential pressure, treatment capacity and applicable hygiene management requirements. Arrangements may differ with equipment and operating conditions.
Retain the model, installation date, operating information and maintenance records. When problems arise, investigate the cause first rather than considering only how many months the cartridge has been used.

What is a reasonable filter cartridge replacement interval?
Model instructions, actual water quality and operating conditions all affect maintenance. Without the relevant information, do not promise a universal interval in months. Establish records first, then confirm the basis for inspection and replacement.
