Hi,
I have purchased Dr. Aqua guard magna RO+ UV in November 2015(18 months back) and at the time of installation the representative told me that filters needs to be changed every year(and, he did not guide me what filters needs to be changes and why) and I got only 2 services and committed to me was 3 services while purchase.
When I called customer care about the service, they said filters needs to be changed after 7000 ltr water usage. Need to know every thing, if any one can guide about service, changing filters, AMC, etc.
