I am a Vet.Doctor by profession, I installed a Kent Supreme in my chamber.The water quality has improved a lot, besides the reject water tank which collects the raw water after purification is a new technique.
Because the other water purifiers I used prior to these in the chamber, all had to be kept a check on, since it used to overflow after filtering the water.
And after the raw water gets collected in the Reject water tank I can reuse the water for cleaning and washing purposes again, which actually is an unique thing and I am happy with this. Prior to this I have also used Kent Grand Plus at home.
