CuZn Under Sink Water Filter
Score: 88/100
Waterdrop Countertop Filter
Score: 88/100Rankings
The CuZn UC-200 is a high-performance under-sink water filter designed for municipal water, offering a 5-year lifespan and a high flow rate of 2 GPM. Its primary limitation is its large physical size, which may not fit in all under-sink cabinets, and it does not reduce TDS. It is best suited for households seeking low-maintenance, high-flow filtration that improves taste and removes heavy metals.
The Waterdrop WD-CTF-01 is a countertop faucet filter with 5-stage filtration and an impressive 8,000-gallon lifespan. Its bulky design and lack of TDS reduction are notable trade-offs. It is ideal for renters or households seeking long-lasting, mineral-enhanced filtration without under-sink installation.
