How We Chose These Whole-House Filters
We compared whole-house water filters by certified contaminant reduction, flow rate for whole-home use, filter life and cost, installation needs and value. We researched and spec-checked each system and its certifications and reviewed owner feedback rather than claiming hands-on testing. Systems undersized for household flow were downgraded.
Key Takeaway: Whole-house filtration is about flow, not just filtration. A system must keep up with every tap and shower running, so match it to your household’s peak flow rate, or you will lose water pressure throughout the home.
