The iSpring RCC7AK (about $269) adds a sixth stage to its process with an alkaline remineralization step for a more balanced, natural taste. In addition, healthy levels of minerals like calcium and magnesium are restored after the initial filtration.

What reviewers didn't like

Most of the customers aren’t satisfied with the alkaline remineralization filter which doesn’t really increase the pH of the water to alkaline state.
PH filter not 100% efficient. Doesn’t completely replenish all mineral loss.
Unfortunately, there is some water wasted whenever you use reverse osmosis. The waste to RO water ratio is 1:2 for this system. That means that for each gallon of clean water it makes, 2 gallons of water are wasted.
A little bulkier than similar models
The filter life is shorter than some competitor systems
