6. Under-Sink RO With a Separate Storage Tank

How to Choose an RO Purifier

Know your water. Get the TDS of your supply tested. RO suits water above about 500 TDS, and UF-only units suit municipal water with low TDS. RO+UV suits varied conditions.

Check storage and speed. A tank of 7 to 10 litres suits families, and a purification rate of 15 litres per hour or more keeps up with demand.

Consider running costs. Filters, membranes and servicing add up. Check annual maintenance contract costs and the availability of technicians.

Common Mistakes to Avoid

Ignoring TDS. Test your water.

Overlooking wastage. RO wastes water, so consider reuse.

Skipping servicing. Change filters on time.

Buying without checking service. Confirm local support.

Real-World Scenarios

A city home with municipal water. A multi-stage purifier with a TDS controller suits.

A home on borewell water. Look for strong RO and a good pre-filter.

A family that wants hot water. Consider a premium model.

What to Check on the Listing

Confirm the stages, the tank size, the purification rate, the filter life and the warranty. See annual maintenance costs.

Quick FAQ

Does RO remove minerals? It removes many, and a TDS controller keeps some.

How often do I service it? Typically every six to twelve months.

How long do they last? Eight to ten years with servicing.

Installation, Servicing and Reject Water

Installation requires a water inlet, a drain and a power point near the location, and most brands include it. Ask about the annual maintenance contract, which typically covers filter changes and servicing visits. RO purifiers reject a significant share of the input water, so collect it in a bucket for mopping, plants or cleaning.

Water Testing and Certification

Ask for a TDS reading of your supply before you buy, and check whether the purifier lists relevant certifications. A good installer will run a test after installation to confirm output TDS, and you can use a handheld TDS meter to monitor over time.

Recommendation

For most homes, the Kent Grand Plus or Aquaguard Aura is a well-supported pick. For smart alerts, consider the AO Smith X8, and for hot water, look at the Z9.
