Replace on schedule to maintain peak contaminant removal and flow rate.

Why Use Genuine Replacement Filters?

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

Always use the replacement filter specified for your system model. Using the wrong cartridge can compromise performance and void your warranty. If you’re unsure which filter fits your unit, contact our water specialists for help.
