Filter Replacement
How to know when it's actually time
Typical replacement intervals
| Filter type | Typical interval |
|---|---|
| Sediment / PP cotton | 3-6 months |
| Carbon block / granular | 6-10 months |
| Ultrafiltration membrane | 3-7 years |
| Reverse osmosis membrane | 1-2 years |
| Post-filter / polishing carbon | Annually |
Key takeaway
By the time performance visibly drops, you've likely been drinking through a partially spent filter for a while. Replace on schedule, not just when noticed.
Signs it's time sooner
Reduced flow rate, return of taste/odor, visible discoloration, or a noticeable change in water clarity - all point to a filter that's reached its capacity ahead of schedule.
Frequently asked questions
- What happens if I use a filter past its date?
- Performance gradually declines rather than stopping abruptly - reduced removal, slower flow.
- Does well vs. city water change the schedule?
- Yes, significantly - well water typically requires more frequent pre-filter changes.
