Many places is Noida receive uneven water supply. Sometimes with high TDS level. So its better to go for RO Water Purifier brand which gives amc(annual maintenance contract) along with the RO.

This AMC gives free of cost replacement of any part while under contract. For example if you take two year amc with a new water filter then first year of your filter is covered under warranty. After first year this 2 year amc starts and in next two year your would get free service visit every 6 months and free replacement of pre filter, carbon filter, sediment filter, RO membrane, UV filter, RO motor pump, power adapter & water tank etc. Though we recommend pre filter to be changed every 2-3months depending on Noida water quality as it would increase the life of RO membrane.
