RO Water Purifier Service Guide: When to Change Filters

25 Oct 2026 · 2 min read

Learn how often an RO purifier needs service, signs that filters or the membrane are exhausted and why water quality matters more than the calendar.

Overview

An RO purifier cleans water only as long as its filters and membrane are in good condition. Waiting too long between services can make the water taste bad, reduce the flow and put extra load on the pump.

What the filters do

  • Sediment filter: removes dust and visible particles.
  • Carbon filter: reduces chlorine, odour and bad taste.
  • RO membrane: reduces dissolved salts and many impurities.
  • Post filters or UV or UF stage, depending on the model: add extra protection.

How often to service

The right time depends on the brand, the model and the quality of your incoming water. As a rough guide, pre-filters are changed every few months and the membrane lasts from one to three years, but heavy use or high TDS water shortens this. Check your manual and ask for a TDS reading at every service.

Signs it is time for service

  • Slow flow or the purifier runs for a long time to fill the tank
  • Water tastes salty, bitter or has a smell
  • The purifier shows a service or filter alert
  • Unusual noise from the pump
  • Water leaking from the connections

Good habits

  • Use a purifier that matches your water source, such as tap or borewell water.
  • Do not ignore service alerts.
  • Keep the tank covered and flush it before first use after a long break.

Frequently asked questions

How often should RO filters be changed?

It depends on the model and water quality. Pre-filters are commonly changed every few months and the membrane every one to three years. Check the manual and a TDS reading.

Why does my RO water taste salty?

This can be caused by an old membrane, very high TDS in the incoming water or an exhausted carbon filter.

Is an annual RO service needed if the water looks clear?

Yes. Filters can be exhausted even when the water looks clear, so a service and TDS check are still worthwhile.
