Whole-House vs Point-of-Use Water Treatment: Choosing the Right Layer
POU RO/GAC targets drinking/cooking; whole-house systems address sediment, hardness, or volatile chemicals at every tap—with tradeoffs.
POU protects ingested water efficiently; whole-house treats every tap at higher cost and maintenance.

| Layer | Best for | Watch |
|---|---|---|
| POU RO | Drinking/cooking | Waste water; remineralize taste |
| POU GAC | Chlorine/organics | Media exhaustion |
| Whole-house sediment | All taps | Not metals/PFAS alone |
| Softener | Hardness | Not drinking metals |
| Certs | NSF 42/53/58 | Match claim |
