How Often Should You Service Your RO Water Purifier?
A practical service schedule for sediment filters, carbon filters and the RO membrane, plus simple habits that keep your purifier healthy.
A general service schedule
Exact timing depends on your purifier model, water quality and daily usage. As a general guide:
- Routine service and check-up: every 3–6 months
- Sediment filter: typically every 6–12 months
- Activated carbon filter: typically every 6–12 months
- RO membrane: typically every 1–3 years, depending on water TDS
Follow your manufacturerYour purifier's manual lists recommended intervals for your specific model. Our technician can advise based on your water test during the visit.
Why high-TDS water needs more frequent care
Hard or high-TDS water leaves scale on the membrane faster. Homes using borewell or tanker water often need more frequent servicing.
Simple habits that help
Keep the purifier switched on so water does not sit stagnant, clean the storage tank during service, and do not ignore warning lights or a change in taste.
Key takeaways
- Plan a routine check every 3–6 months.
- High-TDS water shortens filter and membrane life.
- Timely pre-filter changes protect the membrane and pump.
