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

Change your water filter when performance declines, not on a fixed calendar. The right timing depends on your system type (whole-home, RO, carbon, UV), your water quality, and household use. Endless Energy provides no-cost in-home water testing, customized recommendations, and follow-up service for filter replacements and maintenance across Massachusetts, including Newton. A technician will confirm the correct replacement schedule during service.

Quick checks:

• Taste or odor returns.
• Water looks discolored.
• Water pressure or RO flow slows.
