How often should I change my water filter for best performance?

Change your water filter on the schedule recommended by the system’s manufacturer for best performance. Actual timing varies by system type, local water quality, and how much water your household uses. Apollo Plumbing installs and replaces whole-home and point-of-use filters in Everett and nearby cities, and provides ongoing maintenance. Our team can test your water and set the right replacement cadence. A-List members get a drinking water test free. Watch for reduced flow, new tastes or odors, or filter-change alerts.
