RO Purifier Maintenance: A Complete Guide for Pune Homes

Pune's water quality varies significantly by area — some parts draw from municipal supply with moderate hardness, others rely more heavily on borewell water with higher mineral content. Both affect how often your RO purifier's filters and membrane need attention.

Understanding your RO's filter stages

• Sediment filter: removes visible particles and rust — typically replaced every 4–6 months.
• Carbon filter: removes chlorine and odour — usually replaced alongside the sediment filter.
• RO membrane: the core purification layer — replaced every 12–18 months depending on input water TDS levels.

Signs your RO needs servicing

• Noticeably slower water flow from the tap
• A change in taste or smell of the purified water
• Higher-than-usual wastewater ratio
• Visible discoloration in the storage tank

Why an AMC makes sense for RO purifiers

Because filter life depends on usage and input water quality — both of which are easy to lose track of — an Annual Maintenance Contract (AMC) removes the guesswork. Under AMC, filters and membranes are checked and changed on a fixed schedule, and repair visits are prioritized without an additional visit charge.

If you're unsure when your RO was last serviced, a quick TDS check by a technician can tell you whether the membrane is still performing within range.
