TDS, or total dissolved solids, represents the combined content of inorganic salts and organic compounds in a specified water volume. These substances encompass both beneficial and harmful compounds dissolved in the water, including common inorganic ions like calcium, sodium, magnesium, potassium, iron, lead, arsenic, carbonates, bicarbonates, nitrates, sulfates, and chlorides. Additionally, water can contain dissolved organic matter such as hydrocarbons, herbicides, insecticides, fulvic acid, and humic acids sourced from industrial effluents.

Why is TDS Level in Water Crucial?

• Health Implications: Elevated TDS in water may harbor sodium, potassium, and chloride, but also potentially hazardous substances like cadmium, nitrate, and arsenic. Consumption of water with these contaminants can lead to various health issues, particularly impacting children whose immune systems are still developing.
• Taste Variation: The composition of dissolved solids can alter the taste of water, resulting in unpleasant or salty flavors.
• Health Concerns: Certain substances found in water, such as lead or copper, can pose health risks when consumed.
• Impact on Filters: High TDS levels can affect the efficacy and lifespan of water filtration systems, necessitating regular checks and maintenance of purifiers.
• Culinary Influence: While high TDS levels might not directly affect health, they can modify the taste of cooked food or beverages made with the water.
• Household Effects: Water with high TDS levels can leave stains on kitchenware, clothing, and contribute to bacterial growth in sinks and faucets. Additionally, it can cause scale buildup in pipes and appliances, reducing their durability.

Is Low TDS Harmful?

Low TDS alone doesn't determine water quality as it solely indicates the total dissolved solids present. Numerous types of contamination, including modern toxins from industrial waste and misused pesticides or fertilizers, contribute to water quality issues. Invisible and tasteless, these contaminants can pose severe health risks, emphasizing the importance of high-quality water purifiers.

The optimal TDS level in drinking water, as per the Bureau of Indian Standards (BIS), is set at 500 ppm, relaxable up to 2,000 ppm in the absence of alternative water sources. This standard varies if water contains specific toxic contaminants like arsenic or fluoride.

What is TDS in water, and monitoring them remains crucial to ensure safe consumption, avoid taste alterations, prevent health hazards, and maintain the overall quality of water for household and culinary purposes. Pureit water purifiers prioritize removing harmful substances, providing water that meets safety standards and tastes great. Testing TDS levels helps ensure your water is free from harmful contaminants and maintains an acceptable taste profile.
