How to choose
Match grain capacity to bathroom count
Grain capacity states how many grains of hardness a system treats before it regenerates. The Aquasure pairs 32,000 grains with 1-2 bathrooms, while the Tier1 pairs 32,000 grains with 3-4 bathroom homes, so bathroom count matters alongside grains. The AFW Filters system serves households of 2-5 people at 48,000 grains, and the DuraWater system offers 48,000 grains with twin tanks. Compare the bathroom figure and the grain figure together before choosing.
Metered regeneration and control valves
A metered control tracks water use and starts regeneration only when required. The Aquasure uses a programmable digital display for auto-flush intervals set by water quality and usage. The DuraWater uses a Fleck 9100 SXT metered control valve, and the Tier1 uses usage-based monitoring. The AFW Filters system uses a Fleck 5600SXT digital meter valve. Compare valve type and control style, since both decide how regeneration is timed.
Carbon filtration, resin and upkeep
Carbon filtration sits alongside softening only on the AFW Filters system, where upflow carbon removes chlorine and chloramines, pesticides, herbicides, organics, MTBE, and THM. Resin differs too: the AFW Filters system uses 10% resin, and the Tier1 system uses 1 cubic foot of NSF/ANSI 44 certified resin. For upkeep, the Tier1 valve warranty extends up to 5 years with registration and one bottle of cleanser every 3 months.
