Score: 75/100
Icepure Under Sink Filter
Score: 85/100Rankings
The ICEPURE Under Sink Water Filter System is a single-stage, direct-connect unit certified to remove heavy metals and chlorine with a high flow rate exceeding 2.5 GPM. Its primary limitation is the lack of TDS reduction and multi-stage filtration depth compared to RO systems. It is ideal for DIY users with municipal water seeking quick installation and long filter life in tight under-sink spaces.
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.
