Whole-house filtration (also called point-of-entry treatment) installs where the water line enters your home, so every faucet, shower and appliance gets filtered water. It's different from a drinking-water system like reverse osmosis, which polishes water at a single tap.
What whole-house filtration addresses
- Chlorine & chloramine — taste, odor and dryness on city water. See SHIELD Chlorine & Chloramine.
- PFAS, lead & cysts — SHIELD Health-Related Contaminants.
- Sediment & turbidity — SHIELD Sediment filters.
- Iron, manganese & sulfur odor on wells — the MM-OX iron filter.
- Bacteria & viruses on wells — UV disinfection and ultrafiltration.
City water vs. well water
On city water, filtration usually targets chlorine/chloramine, taste and sediment. On well water, it's about iron, sulfur, sediment and microbial safety — and the right train depends entirely on your water test.
The complete setup
Whole-house filtration works best alongside a water softener (for scale) and a reverse osmosis system at the kitchen (for drinking water). Together they cover scale, contaminants and great-tasting drinking water. We design the combination around your test results.
