“WQA Gold Seal product directory (find.wqa.org, keyword "Aquasana"), read in a browser 2026-10-23. Under Aquasana Inc., "Claryum 3-Stage Max Flow" models AQ-5300+ and AQ-6300M (Plumbed-In to Separate Tap) are listed under NSF/ANSI 42 (aesthetic chlorine, chloramine, taste and odor, nominal particulate class I), NSF/ANSI 53 (reduction claims: asbestos, cyst, lead, mercury, MTBE, PFOS, PFOA, turbidity, VOC as chloroform) and NSF/ANSI 401 (emerging compounds, including microplastics). Aquasana's own product page (aquasana.com, read the same day, model AQ-6300M-BN) states "WQA tested and certified to NSF/ANSI Standards 42, 53 (includes P473), and 401 for the claims specified on the Performance Data Sheet" and an 800-gallon or six-month filter life. IAPMO R&T's directory lists Aquasana (files WC-31171 to WC-31174, WP-10706, WP-10707, WP-12506) but only for other models, not this one; the WQA listing is the one that carries it. The registers show the standard and claim list per model; they do not show the percentage figures on the box.”
