Does your tap water just leave a little something to be desired? The water with high TDS can alter taste and can sometimes become a health issue. Making a shocking revelation, the World Economic Forum report stated that as much as 70% of surface water in the country is unfit for use. Luckily, RO purifiers with TDS controllers are a sort of magic in this – they remove all that stuff and make your water super delicious and healthy. I tested some popular models from Kent, Eureka Forbes, HUL Pureit and AO Smith to find the top budget and premium water purifiers that can handle up to 3500 PPM TDS. Read on to discover the best RO water purifier with TDS controller for your home.
List of the best Water Purifier with TDS Controller
The Kent Pearl Star RO water purifier features a simple TDS control knob – just a twist is all it takes to adjust the TDS level and personalize your water.
You will find 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 could lead to some water leakage and moisture buildup underneath. The top section of the purifier has LED display showing power status and filter condition. You’ll even find some handy labels and stickers right on the front, pointing out cool stuff like how it wastes no water and comes with 4 years of free service!
KENT is best known for their in-tank UV sterilization, in this RO I have found that during purification it goes throw the multiple stages RO + UV + UF + TDS Control + UV LED. One of the things I love about this system is how it tackles TDS. I went from having pretty high levels at 656 PPM to way under 100 after filtering.
As if things couldn’t get any better, there is the Kent Pearl which is great. It has this 8-liter transparent tank that you can actually remove from the machine. Cleaning it is quite a breeze even if you are not tech-savvy at all.
You will notice that the tank has no cover and is very much see through which will surely add to your benefit. 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. But the best part? On the top, it has display LEDs that inform you the device’s power status and the status of the filter.

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.
