To improve taste and balance pH, an alkaline filter is added as a final stage in some RO systems. This filter reintroduces essential minerals such as calcium, magnesium, and potassium into the water. Doing so raises the pH to a more neutral or slightly alkaline level (typically 7.0–8.5), enhances flavor, and gives the water a smoother mouthfeel.
In short, the alkaline filter prevents flat water by restoring minerals removed during RO filtration, making the water more pleasant to drink and less acidic.

Is the pump only for those with low water pressure? (i.e. will the system still work when the pump eventually fails?)
I buy bulk filters so it works out to about $16 a set and membranes only need replaced every couple years with heavy use and up to 5 years with light use.
I make about 400 gallons a month for my saltwater aquarium systems and probably another 150 for drinking. It's not that expensive. The systems that take proprietary filters leave you paying the price they want you to pay. I buy larger amounts than most but you can buy smaller amounts on Amazon for carbon/sediment and such at around $5 a filter or less.
