Filters
Check the installed filter stages and actual service history before deciding what needs replacement.
RO maintenance
Routine attention helps you notice issues before they become bigger.
Use this maintenance checklist as a booking guide. Replacement intervals and parts vary by purifier and water conditions.
Maintenance checklist
Check the system, not just the calendar.
There is no single replacement schedule that fits every purifier. Model, usage, incoming water and filter type can change maintenance needs.
- Look for drips, dampness or loose connections.
- Notice whether water flow has changed significantly.
- Do not ignore unusual sound or repeated auto-cut issues.
- Check whether the last filter service is known.
- Share taste/odour concerns during enquiry.
Representative water-purification photography.Avoid guesswork
Do not replace parts just because a generic chart says so.
Ask about your specific model and actual symptoms. Filter and membrane life can differ substantially.
Membrane
Purification performance concerns should be evaluated before assuming the membrane is the cause.
Connections
Loose tubes, fittings or housings can be a source of visible leakage and should be inspected.
Maintenance enquiry
Not sure what service your RO needs?
Send the purifier model and what you are noticing. We can use that information to discuss the likely service requirement.
