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

For most faucet and under-sink filters, replace the cartridge at least every 3 months for best performance. Whole-home systems are low-maintenance but still need regular filter changes to keep contaminants out. Reverse osmosis and drinking water systems follow a schedule based on water use and quality. We offer free water quality testing and maintenance plans with routine filter changes and annual inspections for Elkhart-area homes.
