A far-infrared remineralization filter that adds a broad spectrum of trace minerals while keeping TDS low (only +1–3 ppm) and pH near neutral — for those who want minerals back without a heavy mineral taste. Fits 1/4″ and 3/8″ tubing.

What it does

This far-infrared 58-mineral filter (MINERAL58) is a final-stage cartridge that reintroduces a broad spectrum of trace minerals to RO water. Its distinguishing feature is a light touch: unlike remineralizers that spike mineral content, it keeps pH near neutral and raises TDS only 1–3 ppm — ideal if you want minerals back without a strong mineral taste.

It uses far-infrared ceramic media plus a mineral media that releases roughly 58 trace elements (calcium, magnesium, zinc, selenium, and more). Installed as the final stage after RO. This is a taste-and-mineral enhancement step, not a contaminant filter.
