When to Replace Your Filter

1. Check your system manual for the rated gallon capacity or time interval
2. Watch for reduced flow rate — a sign the filter is clogged with sediment
3. Monitor taste and odor changes in your filtered water
4. Replace every 2–6 months depending on usage and water quality
5. Set a reminder at purchase to stay on schedule
