Whole Home Systems
XL Whole-Home Softener + Filtration
64,000 grains. Same system, more capacity between regenerations.
Identical hardware to the Standard — the difference is real softening capacity, not a trim level. Built for larger homes, more people, or water hard enough that a 48,000 grain system would regenerate more often than you'd like.
Best for: Larger homes, bigger families, or harder water
