When to Replace

A drop in flow rate, rising contaminant levels on a periodic water test, or reaching the one-year mark are the three signs it’s time. Tracking your install date is the most reliable approach — performance on a spent cartridge tends to decline gradually rather than stopping abruptly, which makes it easy to miss. A calendar reminder set at installation keeps you ahead of it. Reordering a little early costs far less than running an underperforming system for months without realizing it.
