Its better then Aquaguard . I had done lots of research on purifier and then settle for this.
First of all, if you go on compare the price of aquaguard ro plus uv. you will find its cheaper then aquaguard.
The purification process is very good. before purifier. the taste of water was not good to my tongue. but after installing it. the taste of water has changed. and not its better.
It has 6 stage purification system.
The guy who came up for installing it was a very nice guy. and TATA's service is very good. and yes its a Indian brand.
You will dont need have to change the filter for atleast 1 year of the starting.
Overall. you will dont find a UV plus RO at a price of around rs 15, 000 performance wise very good.
I strongly recommend this purifier.
