RO systems –The Aquaguard water purifier RO or reverse osmosis is one of the most widely used water purification mechanism used today given the fact that H2O in most regions of India is hard and has high level of total dissolved solids (TDS). The most vital components in an RO system are the filter cartridges incorporated. Every Eureka Forbes water filter in the RO category features at least four levels of purification, ensuring that every drop of H2O that flows from its faucet is safe and pure.

Four different filters incorporated in common in the RO Eureka Forbes water filter are clarity cartridge, organic remover cartridge, reverse osmosis membrane, and taste enhancer cartridge. Each has its own unique role to play, contributing step by step, the effectiveness of purification. Whether the source of H2O is bore well or municipal, you will find traces of dirt , sand, and other suspended particles in it. The clarity cartridge facilitates effective removal of the suspended particles. It is the first step of purification in the RO Eureka Forbes water filter. The next step of purification happens with the organic remover cartridge. Whatever excess chlorine and organic impurities are left out during the first step, are trapped in the second stage of purification. H2O in most regions is bad in taste and emanates odor. This filter absorbs the same. It is the thin film composite (TFC) RO membrane that is used in the RO Eureka Forbes water filter. This membrane reduces TDS, removes hardness, and eliminates disease-causing micro organisms like bacteria and virus besides heavy metals, pesticides, and other new age tough contaminants. Purification becomes complete at this stage. But, Eureka Forbes does not leave any scope for any residual impurities to flow from the faucet and hence the incorporation of taste enhancer cartridge. It removes residual organic impurities and revives the original taste of water. Polishing of the purified H2O happens with carbon granules, giving it a sparkling, crystal clear look.
