Whole House Filtration Systems
Point-of-entry protection for every tap
Whole-house (point-of-entry) systems sit where your water line enters the home, so every faucet, shower, and appliance gets filtered water. They are the backbone of a serious water strategy — especially on chlorinated city water or wells with sediment and iron.

How to Choose: Whole House Buyer's Guide
Match capacity to your household
Capacity is rated in gallons before the media is exhausted. A family of four uses roughly 100,000–150,000 gallons a year, so a 1,000,000-gallon system lasts 6–10 years before a media swap.
Flow rate matters more than people think
Look for 9–15 GPM. Undersized systems cause pressure drops when two showers run at once. Match the system's GPM to your peak simultaneous demand.
Carbon + KDF is the proven combo
Catalytic carbon handles chlorine, chloramine, taste, and odor; KDF media reduces heavy metals and controls bacteria growth in the tank. For PFAS, confirm the system uses a dedicated PFAS-rated stage.
