CuZn Under Sink Water Filter
Score: 88/100
Frizzlife SK99
Score: 88/100Rankings
The CuZn UC-200 is a high-performance under-sink filter featuring a 5-year lifespan and KDF-55 technology for effective contaminant removal without sacrificing flow rate. Its primary limitation is its large physical size, which may not fit in all under-sink cabinets, and its inability to reduce TDS. It is best suited for households with municipal water seeking low-maintenance, high-flow filtration.
The Frizzlife SK99 NEW is a highly rated, NSF-certified under-sink filter that offers a direct-connect installation and a high 2 GPM flow rate. It excels in contaminant removal, including PFAS and lead, while retaining beneficial minerals. The main limitations are its sensitivity to water hardness and temperature, and it does not reduce TDS. It is ideal for families seeking premium protection without renovation costs.
