Reviews
In-depth reviews of the systems readers ask about most. We read the certification listings, manuals and warranty terms, work out the 10-year cost, and collect the complaint patterns owners report.
We do not lab test systems ourselves, and our reviews say where each fact comes from. For quick specs on 56 systems, use the system finder.

Aquasana HealthShield review
Aquasana HealthShield review: WQA-certified for five PFAS, but a $1,749 tank every 165,000 gallons puts 10 years at $11,000 to $14,500. Who should pay that.
