Water is the vital element without which no form of life is possible. It is why astronomers and other scientists rejoiced when there was news about finding traces of water on Mars.
It opens up possibilities of finding life on Mars. Now, water is available on plenty on the Earth. However, 97% of the Earth’s water is either in the seas or locked up in the form of ice in the glaciers.
That leaves us with about 3% of water for human and animal use. When we say human use, it includes consumption for residential, commercial, industrial, and agricultural purposes.
Secondly, the purity of the available water is a source of significant concern. The water available for human consumption contains dissolved salts, industrial effluents, animal and human waste, and different kinds of impurities.
It brings us to the importance of having water purifiers in our homes. One of the best water purifiers available on the market is AO Smith water purifier.
Let us now discuss the purification technology employed in the AO Smith water purifiers in this simplified buying guide.
