Yes. Water with TDS 25 is safe for drinking purposes. However, water with TDS 25 does not contain all the essential minerals in appropriate quantities. Hence, the water with TDS 25 does not taste good. It is advisable to add some minerals like calcium and magnesium by passing the water through mineralizer cartridges to increase their content and make the water taste good.
Is TDS 5 safe for drinking water?
Water with TDS 5 is safe for drinking because it is as good as pure water. Such water has a pH level of 7, which is ideal. But water with TDS 5 does not have any taste because it does not contain essential minerals like calcium and magnesium. Even the WHO stipulates that water with TDS levels 100 up to 300 ppm is safe for drinking. So, the solution is to add essential minerals to water with TDS 5 and make it suitable for drinking.
Is TDS 10 safe for drinking water?
From the safety angle, water with TDS 10 is safe for drinking. However, if we look at the taste factor, water with TDS 10 does not have much taste. It tastes bland. BIS stipulates that the ideal TDS levels in drinking water should be 100 to 500 ppm. Therefore, RO water purifier manufacturers use various methods to add more TDS to the RO-purified water and improve its taste.
Is TDS 15 safe for drinking water?
Yes. TDS 15 is safe for drinking water, but does the water taste good? The answer is No because TDS 15 does not contain essential minerals like calcium, magnesium, and others in the right quantities. The RO purification process removes all TDS, including essential minerals. Therefore, replenishing the minerals becomes necessary to improve the water’s taste.
Is TDS 20 safe for drinking water?
Yes. TDS 20 is safe for drinking. However, WHO and BIS consider TDS levels below 50 ppm unacceptable for drinking because water with TDS less than 50 ppm does not contain minerals like magnesium and calcium. Therefore, the water with TDS 20 is safe but does not have the necessary taste. So, water with TDS 20 is not recommended for drinking purposes.
Is TDS 35 safe for drinking water?
The World Health Organization stipulates that water with a TDS of less than 50 is not considered suitable for drinking. However, that does not mean the water is unsafe. Water with TDS 35 is safe for drinking but will not taste well because it lacks minerals considered suitable for our consumption. Hence, RO water purifier manufacturers use various methods to add essential minerals and increase TDS levels in RO-purified water to enhance its taste.
Is TDS 50 safe for drinking water?
TDS 50 is considered suitable for drinking by the World Health Organization and BIS. Though the water is safe for human consumption, it lacks essential minerals like sodium, calcium, and magnesium. Therefore, water purifier manufacturers use mineralizer cartridges or other methods like TDS controllers to improve the content of essential minerals in RO-purified water and its taste.
Is TDS 300 safe for drinking water?
The WHO clarifies that water with a minimum of TDS 50 is suitable for drinking. It has fixed an upper limit of 300 ppm. BIS has recategorized the limits and increased the upper limit of TDS to 500 ppm in India. Therefore, water with TDS 300 is suitable for drinking. However, whether it is safe will depend on the TDS content in the water. You can act safe and use an RO water purifier to reduce TDS levels and make it better suited for drinking.
Is TDS 350 safe for drinking water?
TDS 350 is considered unsafe for drinking by WHO standards. However, BIS has relaxed the upper TDS limit in India and increased it to 500 ppm. Therefore, water with TDS 350 is considered suitable for drinking in India. Nevertheless, much depends on the TDS content in the water. Using an RO water purifier to remove TDS is a better option.
Is TDS 400 safe for drinking water?
Water with TDS 400 is not safe for drinking according to WHO standards. However, BIS recommends that water with more than 500 ppm TDS requires RO water purification. However, if you live near industrial areas or the water has a high content of heavy metal contaminants like lead, mercury, and arsenic, using an RO water purifier is the recommended option. It is better to be safe than sorry.
