High TDS water is very common all over India. It can make water taste salty, bitter, or just “off” and leave residues of salt and hardness in your appliances and pipes. RO (reverse osmosis) is the only effective method to remove excess dissolved salts while ensuring safe drinking water. We’ve compared top models of water purifiers, looked into their specifications, and read hundreds of customer reviews to make a list.
Here are 11 best water purifiers for high TDS in India.
What TDS is, safe limits, its effect on taste and health
TDS stands for Total Dissolved Solids. It indicates the quantity of salts, minerals, and metals present in the water, expressed as parts per million (ppm). The BIS IS 10500:2012 Indian standard specifies 500 ppm as the acceptable limit, with a permissible limit of 2000 ppm.
Several experts consider 50-150 ppm as ‘excellent’ and 150-300 ppm as ‘good’. Excessive TDS levels give water a salty or metallic taste. Moreover, it contributes to the risk of metallic poisoning and leads to white scale formation in geysers and iron vessels and kitchen utensils. If your TDS level consistently exceeds 500 ppm, you should get an RO-based water purifier.

RO vs UV vs UF: what they do and where they fit
RO (Reverse Osmosis) is the biggest gun. It pushes water through a very dense membrane to remove dissolved salts and heavy metals. The only technology capable of reducing high levels of total dissolved solids (TDS), RO is a must-have if you live in an area with high TDS.
UV uses ultraviolet light to kill bacteria and viruses. Although effective in eliminating germs, it is unable to remove salt content.
UF (Ultrafiltration) acts as a net to keep out particles such as dust and bacteria. Unfortunately, just like UV, it too does not address the issue of salt content in water.
If you live in a region with high TDS, investing in an RO water purifier is non-negotiable. But good-quality purifiers come equipped with multiple technologies. So, invest in a purifier that features RO along with UV or UF filters. These products can provide effective removal of physical impurities as well as microbial contaminants.

How We Finalised This List
We considered the practical features which contribute to ease of usage in our daily lives. As it can work with brackish or borewell water, we opted for purifiers which have the capability to handle up to 2500 ppm of Total Dissolved Solids (TDS).
Given that conventional RO+UV/UF filtration systems are necessary, we chose products with built-in mineralizers or TDS controllers to enhance the taste. Most families can opt for purifiers with tanks ranging from 6 to 15 liters with a capacity to dispense approximately ~20 L/hr of filtered water per hour.
We have given importance to companies with reliable customer service networks such as Eureka Forbes, KENT, and AO Smith along with online platforms such as Urban Company that provide maintenance-free products valid for up to 2 years.
We checked for safety certifications like ISI available in the Proven Nexon Aqua and adherence to IS:10500 standards of drinking water quality.
Lastly, we considered factors that contribute to long-term costs, including the lifespan of the filters (e.g., Native’s 2-year replaceable cartridges) and annual maintenance costs rather than the product’s market price.

Key Features to Look for Before You Buy
First, check if the purifier has TDS control features. You need a water purifier with adjustable TDS levels. The standard RO purifiers remove everything, leaving behind dead water. The TDS control feature allows you to retain essential minerals from your water.
Secondly, look out for the mineralizer/alkaline cartridge. These enhance the presence of calcium & magnesium, giving great taste and improving overall well-being.
Thirdly, check the storage capacity according to the number of family members. Big families can opt for 8-10 liter tank capacities. Small families with one or two members can choose 6 litter units.
Lastly, check the water-wastage ratio. Old generation RO purifiers consume a huge amount of water. Modern-age water purifiers are highly efficient in conserving water. Choose one that boasts about its high recovery rate or minimal water waste.

Maintenance and Ownership: What to Expect
A water purifier requires regular maintenance to keep it running smoothly. You will have to replace its filters. The sediment filter and carbon pre-filter need to be replaced every 6-7 months. While the RO membrane has a longer lifespan, typically lasting for 1 to 2 years. The UV lamp needs to be replaced every year. You should make provision for such expenses.
You can expect to set aside between Rs. 3,000 and Rs. 5,000 each year for water purifier maintenance and replacing filters. It is good to consider taking up an annual maintenance contract, or AMC. This generally includes regular services and filter replacements.
Regular servicing through an AMC helps you save money compared to booking individual service visits. Keep the outer part of the machine clean and also clean the storage container from time to time to maintain good hygiene.

Simple Tests You Can Do at Home
To find out if your air purifier is doing its job properly, you can perform some simple tests. The simplest one is to buy a TDS meter, which is available at low costs online. Test your tap water followed by testing the filtered water. If your air purifier is effective, the TDS reading of purified water should ideally be less than 150 ppm.
Another simple test is the chalk test. Fill a glass with a small quantity of water and let it evaporate completely. If a thick layer of white deposition can be observed, it indicates that the total dissolved solids (TDS) level in your water is still high.
One can also rely on our sense of smell and sight. If your water smells of chlorine or appears to have an unusual color, it could indicate that your filter is clogged and needs to be replaced.
Our Final Words
If you live in an area with high TDS levels, then you don’t need to get bogged down by the decisions needed to choose the right product.
For a smooth and hassle-free experience in the long run, the Urban Company Native M1 and M2 Pro come highly recommended. Their 2-year filter lifespan and warranty offer excellent peace of mind.
If you are looking for features such as hot water or under-sink installation, the AO Smith Z9 and Z2+ Luxe provide strong performance capabilities.
KENT Grand offers reliable solutions with widespread availability of service centers. If budget is a concern, products such as Aquaguard Delight NXT, AQUA D PURE Copper, Kinsco Aqua Punch, Proven Nexon Aqua, and iSpring Mineral RO offer great value.
Frequently Asked Questions (FAQs)
Do I really need an RO?
Yes, only if your water TDS exceeds 300-500 ppm. If it is less than this, a UV purifier would be sufficient.
Is boiled water better than RO water?
Boiling makes water free from bacteria but does not eliminate dissolved solids and metal contaminants. An RO system does away with all types of physical and chemical contaminants, including dissolved solids and metals. An RO system is better.
How much water does an RO waste?
Depending on the model of the system. Latest systems contribute to around 50-60% of the wastage of water. The wastewater can be used for cleaning floors or for watering plants.
What is a UV chamber in RO?
It’s an added layer. RO removes physical impurities. UV kills any living microorganisms that might pass through.
