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.

You can buy 3 year supply of filters for $90 from their website. If your municipal water is not too bad, you can multiply filter life by 2.

You may be able to find it a little cheaper at home depot.
I can easily go 2 years on a membrane and as long as I change the prefilters once a year im still under 10ppm.
The $90 3-year kit will last me 6 years easily.
This is a generic kit using off the shelf parts. If you look up "reverse osmosis filter" you will find many results by different brands that all look the same, and you can expect them to work pretty much the same. In most cases the replacement filter kits are interchangeable too, but your mileage may vary.
I add some trace amounts of magnesium and epsom salt to RO water in order to improve the taste of the pourover coffee. For drinking and cooking, we prefer the RO water with no minerals added back. Usually our ppm reader will read ~40-45 with the recipe we use.
For my espresso machine, we add a little bit more minerals as the manufacturer recommends not using pure, distilled or RO water without remineralization (voids the warranty). Usually the ppm reader will read ~100-125 with the recipe we use for espresso water.
We have an APEC system with the high flow (model# RO-HI) and love it. Fills up our glass or coffee machine tank super fast. We bought it for $167+tax in July 2024, however it seems the prices are now north of $250 (thanks to tariffs?).
The system has the standard 10" housing so you can use any generic cheaper filter from iSpring, EspressWater or other companies. The push-to-connect couplings make it very easy to self-install.
