KENT Grand Plus Alkaline + Copper RO

Why it's our Upgrade pick

• RO, UV and UF with TDS control handle borewell, tanker or city water, with a 9 L tank and 20 litres an hour of output.
• A buying guide names it its best overall pick, and Consumer Voice's older test put Kent and Aquaguard on top.
• Kent advertises service across 19,000+ pin codes, which matters for yearly filter changes.

Watch out: Needs yearly membrane and filter changes, which add to the running cost.
