How Long Does an RO Membrane Last? 4 Signs It Needs Replacing
Learn how long RO membranes really last in Nellore water and catch the four warning signs that yours is due for replacement.
The RO membrane is the heart of your purifier. Every other filter exists mainly to protect it, and once it wears out, purification quietly stops even though water keeps flowing.
How Long Should a Membrane Last?
In typical conditions a membrane lasts around 2 to 3 years. In parts of Nellore where borewell TDS runs high, it works harder and may need replacement earlier. Skipping sediment and carbon filter changes also shortens its life.
4 Signs the Membrane Needs Replacing
- The water starts tasting salty or odd again, even with fresh pre-filters
- Purified water flow drops noticeably and the tank takes longer to fill
- Output TDS climbs closer and closer to your raw water TDS
- The purifier sends much more water to the drain than before
What to Do Next
A technician can measure input and output TDS in minutes and confirm whether the membrane is actually exhausted. Never let anyone replace it purely on age without a reading.
Aquera Solutions checks membranes with proper TDS measurements before recommending replacement, and stocks genuine membranes for all major brands in Nellore.
