Why use RO Water Purifiers?

Drinking impure water has harmful effects on your health, as it acts like a slow poison, causing routine illness like Cholera, Dysentery, Diarrhea, Jaundice, Tuberculosis and even diseases like Cancer. More than 37.7 million Indians are affected by water borne diseases annually, with over 1.5 million children are estimated to die of Diarrhea alone. More than 80% of stomach diseases in India are caused by polluted water.

Increasing Dissolved Impurities

Impurities, especially Dissolved ones are increasing in potable Water whether supplied by municipalities or from Ground well.
Contamination of Groundwater: The underground water has pesticides, insecticides, and harmful chemicals such as arsenic, fluoride & lead.
Pesticides & Chemicals in River Water: Excessive use of pesticides as well as contamination from industrial waste affects river water. These soluble chemicals result in water borne diseases.
Rusting of Pipes: The water from municipalities goes to overhead tank from where it travels through rusted old pipelines, which are also often unclean, causing further water contamination.
Hence it is essential to purify water before you drink. Reverse Osmosis (RO) Water Purifiers are ideal as they don't only kill Bacteria and Virus but also remove Dissolved Impurities which are harmful.
