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

Change your water filter on the schedule recommended for your specific system, because timing varies by filter type, household use, and water quality. Pre-filters usually need changing more often than carbon or reverse-osmosis stages. In Chicago and nearby suburbs like Evanston and Glenview, higher sediment or chlorine can shorten change intervals. A Green Air Care plumber can inspect your setup and set a maintenance cadence that protects flow, taste, and appliance life.

Quick checks:

• Watch for pressure drop.
• Notice taste/odor changes.
• Follow the system’s indicator light or manufacturer guide.
