QUESTION
Query related to water purity especially TDS

Dear team,

Recently I shifted to Gurgaon from Delhi where I had installed a UV at my home. Now in Gurgaon I got the TDS checked for the supply water in the tank at my home by the aquaguard executive and it came out to be 150. Now is it safe to use only UV?? I know the TDS is less than 500, but I am confused as I want to be sure if the nitrates or any other harmful chemicals are also considered under the acceptable TDS amount of 500 or it should be considered seperately and if there could be a risk of any other contamination in the water supplied, which can be avoided by installing RO??

Please give your expert comments as everybody is proposing and favouring their products and I just want to be safe and also do not want to spend unnecessarily.

Thank you
