FAQs

How often should I replace 4-stage domestic filters in an RO system?

Regular pre-filter replacement is typically recommended every 6 months. The membrane element can be replaced every 18-24 months to ensure optimal performance and sustained water purity, although this timeline may vary based on usage and water quality. You can use a TDS Meter to check water quality more closely.

How can I prolong the lifespan of my filters?

Having optimal water pressure (80-100PSI) and optimal water temperature (25°C) will prolong the lifespan of your filters, increase efficiency (resulting in lower TDS from the membrane) and increase water flow.

Can a 4-Stage Domestic RO Filter be installed without professional help?

Yes, our filters are designed for a user-friendly setup. However, if you are having trouble, it is best to consult the system manual or contact our team for support.
