Schedules depend on the system — and your water
Cartridge filters, carbon stages, and RO membranes each have different lifespans. Manufacturer guidance is a starting point; Folsom water conditions and household usage can shorten or extend that window.
Waiting until water taste changes is a late signal. A simple calendar reminder tied to your equipment type is usually better.
Typical replacement ranges
Exact timing varies by brand and water quality, but these ranges help set expectations for many Folsom homes.
- Sediment or carbon cartridges: often every 3–12 months
- RO prefilters: commonly every 6–12 months
- RO membranes: often every 2–5 years, depending on use and water quality
- Whole-house media: follow system specs and service recommendations
Signs you should not wait
Lower water pressure, returning tastes or odors, or visible discoloration can mean filters are overdue. Skipping replacements can also stress other parts of the system.
