Signs Your Water Filter Media Needs Replacing

A master filter's media wears down gradually, and by the time it fails completely, you've usually been living with reduced performance for months. Here's what to watch for.

Dropping water pressure that doesn't recover after a flush is the most common sign — it means the media is clogged deeper than a normal rinse can clear. Water that looks clear right after flushing but turns cloudy again within days suggests the media has lost its trapping capacity, not just picked up a temporary load. A change in smell or taste, even subtle, often means sediment is passing through rather than being caught.

How long media lasts depends heavily on grain quality — finer, denser media (like what we use) holds performance far longer between replacements than the loose sand-and-gravel mix in cheaper units. If you're flushing every few weeks and still not getting pressure back, the media itself — not your flushing routine — is usually the problem.
