I have been using Pureit very satisfactorily. But as I wanted to get rid of Chlorine, I considered Swach for the following reasons :
i) a TATA product (would now like to label it "Tata-Bye-Bye" !)
ii) it also has won medals for design, etc. (now I doubt !)
ii) Kent Gold Plus, a similar product in the offline category, lacks an indicator for changing the filter component
BUT I AM EXTREMELY UPSET and REPENTANT because of the following:
i) Tata Swach is horribly designed to guarantee Leaks and Impure water :
Impure water from upper chamber is leaking into the lower chamber thru the joint of the bulb (i.e. thru the slot where the Bulb attaches to the bottom of the upper chamber), even though the fitting is correct. It seems even the stop-cock is not adequately water-tight.
ii) Their HELPLINE is a HELL-Line ! A Non-existent support network (wonder how/why TATA did this !)
iii) Retellers donot stock/sell spares
