Address:

Bilekahalli Bangalore

Brought Pureit Water Purifier May 2021 and first one year without problems it was working good. But then April 2022 month Gkk2 changed paying 3000rs and again problem came June 2022 technician changed adaptor 1K and this month sept 2022 didn't work and technician came and said motherboard is gone need to change 3500rs said.
Even before completion of 1.5 year, if motherboard needs to be replaced what is the value and quality provided by pureit?
