- IAPMO certification language for NSF/ANSI 42 and 372 is useful for taste/odor and materials claims

Our Verdicts
CuZn UC-200 Under Counter Water Filter
The CuZn UC-200 is the low-maintenance under-sink pick for buyers who mainly want better taste and fewer cartridge changes. Filter Report treats 42/372 as the strong receipt and keeps broader PFAS/lead wording in the caution lane until exact claim receipts are attached.
Waterdrop 15UA Under Sink Direct Connect Water Filter
The Waterdrop 15UA is the budget under-sink pick for taste, odor, chlorine, and low-maintenance buyers. It should not be oversold as a broad health-effect filter unless the exact certified lead or contaminant receipt is present.
