RO Water Purifier Maintenance: When to Change Filters & Membranes

Learn exactly when to change your RO water purifier filters, membranes, and UV lamps to ensure safe drinking water and protect the system from hard water scaling.

Introduction to RO Maintenance

In Pune and MIDC areas, borewell water contains high TDS (Total Dissolved Solids) and hardness. An RO (Reverse Osmosis) water purifier is essential, but neglecting its maintenance renders it useless and turns it into a bacteria trap.

In this guide, we cover RO Water Purifier Maintenance Timelines. At Prime Cool, our appliance technicians service RO systems to ensure safe drinking water.

Key Maintenance Timelines

  1. Sediment & Pre-Carbon Filters (3-6 Months): These filters catch heavy mud, rust, and chlorine. If left unchanged, they choke and force heavy debris directly into the expensive RO membrane.
  2. RO Membrane (1-2 Years): The heart of the system. If your water flow slows to a trickle or the water tastes metallic/salty, the membrane is fouled with calcium scale and must be replaced.
  3. UV Lamp (1 Year): The UV light kills bacteria. Even if it still lights up, its germicidal intensity drops after 9,000 hours. It must be replaced annually for safety.

Expert Troubleshooting

A constantly running reject water pipe (even when the tank is full) indicates a failed auto-shutoff valve or a punctured RO membrane, wasting hundreds of liters of water.

Ensure your family's water is safe. Book an RO service and filter change with Prime Cool.
