Decision rule

Treating every gallon only makes sense when the exposure or nuisance happens throughout the house.

Chlorine/chloramine affect showers, laundry and every tap, so whole-house carbon can be rational. For PFAS, lead and drinking-water contaminants, point-of-use treatment may deliver stronger evidence at lower cost.
