I have bought this Genpure UV+ RO filter 3 years back from Seventh HILL, Mahadevpura Bangalore.
This is a very good water filter with Silver-nano technology. As this is under AMC so, dealer is taking care all the service and maintenance related issues. For AMC you have to spend approx. 3800/- including parts and I think that is almost same for all other brands as they will replace filter/carbon etc everything with 2/3 free services.
Overall its very good product.
