I m using pureit water purifier classic model of 23 liter from last 3 year.
This is best product to pure water.It is automatic so easy to use.
It shows battery indicator.You have to replace battery once it get shut off.Usually it get run around 6 month then indicator shows battery life.
Cleaning is very easy.This model is stylish and good looking and having nice blue color.It also suits to my kitchen.
Pureit having good service and support.
