CuZn Under Sink Water Filter
Score: 88/100
APEC CS-2500P
Score: 75/100Rankings
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 APEC CS-2500P is a compact, non-reverse osmosis under-sink water filtration system designed for high-flow performance and long-lasting contaminant reduction. It utilizes US-made granular activated carbon filters to remove up to 97% of chlorine and 90% of lead, offering a simple installation process without the complexity or wastewater of RO systems. It is ideal for kitchens needing 1.67 GPM for quick filling and renters requiring easy installation.

Professional reviewers and editors praise APEC under-sink systems for their exceptional value, build quality, and performance relative to price. While specific lab tests highlight the superiority of APEC's reverse osmosis models, the non-RO CS-2500P is recognized for its high flow rates and effective contaminant removal. Editors note that APEC's WQA Gold Seal certification in premium models ensures high standards, and the brand generally scores higher in filtration metrics than competitors like iSpring.
Everyday users frequently praise the APEC CS-2500P for its ease of installation and the noticeable improvement in water taste. Common themes include satisfaction with the high flow rate for daily use and the simplicity of the DIY setup. However, recurring complaints involve variability in filter lifespan, particularly in hard water conditions, and occasional installation-related leaks.
