Our Take
The Aquasana AQ-5300+ is a strong all-around performer. Its proprietary Claryum filtration combines activated carbon, catalytic carbon, and ion exchange to remove 77 contaminants. While its 95% PFAS removal trails dedicated PFAS filters, it excels at broad-spectrum water quality improvement including lead, chlorine, herbicides, and pharmaceuticals.
