How often should I replace the reverse osmosis membrane in my whole-home filter?

An RO membrane commonly lasts around two to five years, but whole-home use can make a fixed calendar schedule unreliable. Feedwater quality, prefiltration, pressure, recovery settings, and the amount of water your household uses all affect membrane life. When in doubt, call a professional for an inspection. They will determine whether a worn-out RO membrane is the source of your issues and proceed accordingly.
