When I first bought and started using KENT Prime, I didn’t even know that a certain%age of water is rejected within the purification process. That is when I went back to the KENT website which explains how the KENT Prime saves more than 50% as purified water, and saves the rejected water for non-potable uses, as compared to 20% by other water purifiers.
That, for me, makes it one of the best RO water purifiers in India which contributes to water sustainability as well.
