What is included in the AMC for RO water purifiers

The maintenance cost of RO water purifiers involves the changing of all the cartridge elements in the RO water purifier like the pre water filter cartridges, post carbon filter and remineralizer cartridge. It is advisable to change all cartridges in a RO water purifier, excluding the membrane, once every year. The RO membrane of an RO water purifier is the costliest filter element in an RO water purifier and it costs roughly about RS.2,500-. Normally it needs to be replaced once in every 3 to 5 years, depending on the usage of the RO water purifier.

Wall mounted RO water purifiers have small pre filter cartridges which tend to get blocked quickly and limit the flow of water to the RO pump in the RO water purifier. This will reduce the efficiency of the RO water purifier. So a cheap external 10 inch pre-filter costing about Rs.300- to Rs.400- from the large selection of 10 inch pre-filters on, is highly recommended for any RO water purifier in India, especially for wall mounted RO water purifiers. This 10 inch pre-filter can be mounted away and hidden from the main purifier in a convenient location.

It should be noted that most RO water purifiers in India are of the wall mounted type, and as far as maintenance costs are concerned they tend to be more expensive than the under sink type water purifiers. Wall mounted water purifiers do not use standard size filter cartridges, and hence, such spare cartridges may not be available in the open market. You can only get spares from the manufacturer, and hence you may be compelled to enter into AMC with the manufacturers.

Under Sink type water purifiers have the advantage of using standard size spare parts and hence it is possible to buy spares online or from the open market. Thus there is a yearly saving in maintenance cost if you are going to do the maintenance of your water purifier by yourself. Then it will not be costly, roughly about Rs.600- every 4 to 6 months for a set of all the cartridges that need to be changed in an under sink RO water purifier. Membranes and motors tend to last at least 3 years, more likely 5 years.
