Note: Filters and membrane are consumables. Their replacement time is dependent on the quality of
raw water and water consumption. They are not covered under the warranty. However, if a filter
chokes within six months and a membrane within a year, it will be cleaned/repaired/replaced free of
cost. Changing the filters and system inspection is available on call. The treatment capacity of RO
membrane will reduce with time due to clogging of pores of membranes.
