Iron Pro 2 Combination Softener + Iron Filter — 64,000 Grain (Fleck 5600SXT)

The AFW Filters Iron Pro 2 is a 64,000-grain high-flow unit that combines a water softener and an iron filter on the same Fleck 5600SXT metered valve — built for larger homes and very hard well water where dissolved iron stains and compounds the mineral load. Softening at the source is the most durable fix for dense Asian hair abroad, where water far harder than home is what leaves thick hair stiff and dull; adding iron removal matters on well water, where iron alone can turn hair brassy and rough. It regenerates on demand (metered), drawing salt and water only when you use it. It is a step-up in capacity for big or very-hard-water households; it is over-sized for small households, so choose a smaller grain count there.
