QUESTION
Query on safety levels of household water purifying systems

Hi

How safe are household water purifying systems like HUL, Pureit etc which use chlorine for purification? The manufacturers say that this system involves 4 stage purification and one of them is polishing. Does this process really work for safe drinking water?

Please suggest as millions of people use appliances like these and most of them doesn't know what chemicals are used actually.

Regards
