We all are aware that metro water is contaminated due to its pipeline.so water from reverse osmosis filtration of metro water the health benefits of reverse osmosis filtration water and the content of its mineralisation.
If it removes mineral quantity then the water wont be good enough to our body.but the RO buisness person shows the total deposit salts(TDS).So whether the RO reduces the quantity of TDS in water.you know pipeline water also contains many contaminants.
The membrane used in reverse osmosis retains minerals like Ca, Fe, etc., and can affect bone density in healthy individuals. The final verdict is to use R.O water only in a case when the bone density isn't reducing otherwise mineral water is fine until the ppm exceeds.
