Because it filters more.

Each filter lasts up to 20 gallons; the integrated TDS meter tells you exactly when to replace it.
Both brands reference NSF/ANSI standards, but certification scope differs significantly. Culligan with ZeroWater Technology is IAPMO certified against NSF/ANSI 42, 53, and 401 — covering 26 contaminants including Total PFAS, lead, and pharmaceuticals. Brita Standard covers 5.
