Best Whole-House Water Filter
Most whole-house filters reduce chlorine and sediment well but are not system-certified for health contaminants - pair one with a certified point-of-use filter for drinking water.
Whole-house filters treat every tap, mainly for chlorine, sediment, and taste. A key catch: many are built from NSF-certified media but are not certified as a complete system. We score what the system actually holds.
How we score: We rank whole-house-class systems by composite score and are explicit about media-certified versus system-certified.

FAQ
- Does a whole-house filter remove lead or PFAS?
- Most do not, and few are system-certified for health contaminants. For lead or PFAS, add a point-of-use filter certified for that contaminant at your drinking tap.
