Looking for a water purifier to reduce the TDS in your drinking water? A high TDS level can negatively impact taste and increase AMC cost. TDS controllers allow you to customize the mineral content in purified water. I tested top brands like Kent, Eureka Forbes, HUL, AO Smith, and V-Guard to find the most effective and reliable RO+UV purifiers with TDS controllers. My picks effectively handle input TDS up to 2000 PPM, reduce hardness and TDS by over 90%, and retain useful minerals. Below I have listed the top 7 purifiers with TDS controllers that can handle levels up to 3500 ppm, to help you find one that suits your water quality and budget.
List of the best Water Purifier with TDS Controller
Controlling your water’s TDS is easy with this purifier. A simple twist of the TDS control knob, conveniently located next to the cartridge, lets you personalize your water to your preferred level. Brand says, this water purifier is ideal to control TDS Level up to 2000 PPM, so to proof that I conducted the test my water TDS level was 1560 PPM, it easily converts the PPM to 115 PPM. This TDS level is actually good, contains essential mineral Calcium, Magnesium. Although it has multiple purification methods (RO + UV + UF + TDS Control + UV LED), the purification rate is actually good at 18-20 L/hr. The flow rate is quite good as well, filling a 250 ml glass in under 10 seconds. The price of this water purifier is quite premium, around ₹19,000. At this price, you might expect them to provide stainless steel. However, let me inform you that they offer in-tank UV sterilization as an alternative. So, you shouldn’t have any problems, even if the water is stored for 24 to 36 hours, as it will still be drinkable.
I have found the tap is centrally located on the front of the purifier and made of sturdy plastic in a blue and white colour combination matching the unit. The tap mechanism looks simple and user-friendly to operate. However, I am disappointed with the lack of a drip tray under the tap which you need a separate water collector solution. The top section of the purifier has an LED display showing power status, RO water purification status, and cartridge life indicator similar to a mobile phone’s battery status.
It has this 8-liter transparent tank that you can actually remove from the machine. It rounded in shapes at the edges making it look a bit classy and the use of blue and white tap enhances the look of the kitchen.

Frequently Asked Questions
Does UV Filter Reduce TDS?
No, UV filters do not reduce TDS. They primarily disinfect water by killing bacteria and viruses but do not remove dissolved minerals or salts that contribute to TDS.
When to Use RO for TDS Reduction?
RO is recommended when your water source has high TDS levels, usually above 500 ppm (parts per million). High TDS can affect taste, cause scaling, and potentially have health implications in the long run.

How Often Should I Check the TDS Level in My Water Purifier?
It’s ideal to check the TDS level monthly to ensure your purifier is working effectively. You can use a TDS meter, which is an affordable and easy-to-use device.
Can I adjust the TDS level in my water purifier?
RO water purifiers like KENT and Aquaguard come with a TDS controller or adjuster, allowing you to modify the mineral content of the purified water. This is helpful if you prefer slightly higher mineral content for taste.
