[Resolved]  Kent RO — Running cost of Kent RO

I have purchased Kent RO in 2014 at Hyderabad for my family(2 adults+2 children's) and in initial days RO performed for 3 years without any problem and than following are frequency for replacement of filter kit:

1) First filter kit in 2017 @ Rs.3500/-
2) Second kit on 07.11.2019 @ Rs.6450/-(second replacement)
3) Third kit on June 2020 @ Rs 1800 i.e. within one year.
4) Finally again 4th replacement on 11.06.2021 @Rs.4, 350/- i.e. within one year again.

All above kit replacement is done by Kent RO service center and my source of water is also not changed. It means the product quality of KENT spares are not good and fails normally within one year. So, after purchase of this unit i have spend more than Rs.16, 000/- to keep my RO in running condition. I am attaching some of bills for reference.
