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

Change most faucet-mounted, pitcher, and under-sink filters about every three months for best performance. Whole-house systems typically need less frequent maintenance, but their filters still require periodic replacement based on use and water quality. We offer free water quality testing to help set the right replacement schedule and detect contaminants. In Glendale Heights and nearby Schaumburg or Elgin, our team installs and maintains systems and provides free quotes for installation.
