Your RO filters work silently until performance drops — so knowing the warning signs saves you from drinking under-purified water. The clearest signals are a change in taste or smell, visibly slower flow, more frequent pump cycling, or the purifier taking longer to fill its tank.
Sediment and carbon pre-filters usually need replacement every few months depending on input water quality, while the membrane lasts longer. If water quality dips soon after a filter change, the membrane or a specific stage may be the real culprit.
Don't wait for filters to fail completely — degraded filters strain the pump and shorten membrane life. A quick service check confirms exactly which stage needs replacing.
