This water purifier does not purify your drinking water 100 percent.Actually I have used this purifier in past but then I change my purifier to kent RO with clean your water completely.
There is actually a device which measures the purity of the water in TDS units. I live in delhi with family in zakir nagar and the source water we get has 1000 TDS and my new purifier brings that to almost 200tds.but it can’t be possible with this purifier.well this pureit only cleans the dust particles in the water thats it.If you are in tight budget then only go fo this otherwise if you want safe drinking water then buy some purifier with RO capability.
