TDS Water Purifier
Water quality is one of the most critical aspects of health and wellness. In India, where water contamination levels can vary drastically from one region to another, using a water purifier has become more of a necessity than a luxury. One important term you may have heard in this context is TDS, which stands for Total Dissolved Solids. A TDS water purifier is designed to manage and optimize the TDS levels in drinking water, ensuring it is safe, clean, and healthy.
In this blog, we will take a deep dive into TDS, its importance, how it is measured, the best TDS levels for drinking water, and the role of TDS water purifiers. We will also guide you through the tools used to measure and control TDS, and recommend some helpful links for buying quality TDS meters and adjusters in India.
What is TDS in Water?
TDS refers to the combined content of all inorganic and organic substances contained in a liquid. These substances can include minerals, salts, metals, cations, and anions dissolved in water. TDS is generally expressed in milligrams per liter (mg/L) or parts per million (ppm).
The major contributors to TDS in drinking water include:
-
Calcium
-
Magnesium
-
Potassium
-
Sodium
-
Bicarbonates
-
Chlorides
-
Sulfates
While some of these minerals are essential for human health, too much of them can affect the taste and safety of water.
Why Does TDS Matter in Drinking Water?
TDS is a critical indicator of water quality. Both low and high TDS levels can pose challenges. Extremely low TDS water may taste flat and lack essential minerals, while high TDS water may contain harmful substances like lead, arsenic, and other contaminants.
Effects of High TDS:
-
Bad taste (salty or metallic)
-
Laxative effects (due to sulfates)
-
Possible heavy metal contamination
-
Corrosion of pipes and appliances
Effects of Low TDS:
-
Lack of essential minerals
-
Tasteless water
-
Possible leaching of metals from pipes
Ideal TDS Levels for Drinking Water
The Bureau of Indian Standards (BIS) and World Health Organization (WHO) suggest the following TDS guidelines:
| TDS Level (mg/L) | Water Quality |
|---|---|
| 50 – 150 | Excellent |
| 150 – 250 | Good |
| 250 – 350 | Fair |
| 350 – 500 | Poor |
| Above 500 | Unacceptable |
Ideally, the TDS of purified drinking water should be between 80 and 200 ppm, ensuring a balance of taste and health.
What is a TDS Water Purifier?
A TDS water purifier is a water purification system that not only removes impurities but also manages the TDS levels in water. These purifiers often use Reverse Osmosis (RO) technology, which effectively reduces high TDS. Advanced models also include TDS controllers or mineralizers that help retain essential minerals.
Key Features:
-
RO membranes to filter dissolved solids
-
TDS controllers to maintain ideal mineral levels
-
Multiple filtration stages including sediment, carbon, and UV
-
Better taste and odor removal
How to Measure TDS in Water
To measure TDS levels, you can use a TDS meter. These digital devices give you an instant reading of the TDS in water, typically in ppm.
You can purchase high-quality TDS meters online. Check the following reliable products:
Both options are listed on Romega Mart, a trusted marketplace for water purifier spares and systems across India.
What is a TDS Adjuster?
TDS Adjusters are devices or settings in an RO water purifier that allow you to control the TDS level of the output water. When the TDS is too low, it can be adjusted upward to maintain essential minerals and taste. These adjusters ensure that purified water remains both safe and palatable.

How to Choose the Right TDS Water Purifier
When selecting a water purifier, consider the TDS level of your source water.
If TDS is above 500 ppm:
You need an RO water purifier with a strong membrane to remove harmful dissolved solids.
If TDS is between 150 and 500 ppm:
Choose a RO+UV or RO+UF system with a TDS controller to balance the mineral content.
If TDS is below 150 ppm:
You may not need RO purification. A UV or UF purifier is usually sufficient.
Also, consider buying a purifier from platforms that offer verified products. You can visit Romega Mart to find domestic and industrial-grade RO systems and accessories.
Benefits of Using a TDS Water Purifier
-
Removes heavy metals like lead, arsenic, and mercury
-
Retains essential minerals when used with a TDS controller
-
Improves water taste and smell
-
Reduces the risk of water-borne diseases
-
Ideal for both domestic and industrial use
Frequently Asked Questions (FAQs)
What is a good TDS for water?
A good TDS for drinking water ranges from 80 to 200 ppm. This level balances taste and health, ensuring the water is neither too flat nor too salty.
What is the best TDS for a water purifier?
The best TDS level for a water purifier output is generally considered between 100 to 200 ppm. Most modern RO systems come with a TDS controller to maintain this ideal range.
What is the normal TDS for purified water?
Purified water typically has a TDS ranging from 50 to 150 ppm, depending on the source water and the type of purification process used.
Is 25 TDS safe for drinking water?
Water with 25 TDS is generally considered too low, lacking essential minerals. While it may be microbiologically safe, it is not ideal for long-term consumption due to the absence of minerals.
What is the TDS of Bisleri water?
Bisleri bottled water typically has a TDS of around 120 ppm, which falls in the optimal range for taste and safety.
Can I drink 15 TDS water?
Drinking water with TDS as low as 15 ppm is not recommended for regular consumption. It lacks essential minerals and may taste bland. Long-term consumption can affect electrolyte balance in the body.
Conclusion
Understanding and managing TDS levels in water is crucial for maintaining health and wellness. With increasing concerns over water contamination in India, using a TDS water purifier becomes essential. Whether you need to measure, monitor, or adjust TDS, the right tools and systems make all the difference.
Platforms like Romega Mart offer a wide range of reliable water purification products including TDS meters, TDS adjusters, and industrial TDS and pH meters to help ensure you are always drinking the best quality water.
Make an informed decision, test your water, and choose a purifier that suits your TDS needs to protect your family’s health.
