Why Should You Invest in Kent Supreme Extra?


This model relies on a TDS controller to regulate the TDS level of water purified. Kent states that this TDS controller can maintain the safe levels of vital minerals present in the purified water.

However, truthfully speaking, we do not approve of the TDS controller since it can compromise the quality and safety of your water.

Alerts to change filters and UV fail alarms inform you that the filters or UV lamps need replacement. The purifier ceases all functions when the filters have not been replaced within the next 60 hours after the notification.

These characteristics are what make it a highly dependable and fail-safe water purifier.

The in-tank UV Disinfection is another amazing feature. The UV LED within the storage tank helps keep the purified water clean and safe during longer periods.

This Alkaline Booster feature supports maintaining water pH between 8.5 and 9.5 and, consequently, offers healthy and alkaline drinking water. The Alkaline booster feature tackles the issue of the alkaline nature of RO-purified water.

Although the evidence for scientific studies isn’t as strong, several studies have demonstrated that Alkaline water has various health advantages.

It addresses the most significant drawbacks of using an RO water purifier.

The most effective water purifier has Zero Water Waste technology. This technology returns the water that is rejected into the tank that is overhead, cutting down on water waste to zero.

This is possible because of an internal pump that is robust. The pump can move the rejected water onto an overhead pump, even on the 10th level.
