I am using this device past 4 weeks, Its working perfectly fine.
Since it has RF technology, water is tasty. In my apartment the bore water TDS is 700 and we controlled it to 45 and it has 16 stage filter so output water is healthier.
It has 12ltr capacity tank sufficient for 3 days usage for 2 members. Very limited running cost and maintenance is limited.Leaupure is the working very good. I like very much. We are know this time normal water is very dirty because in water more gurms not safe.
