AquaTru Under Sink
Score: 85/100Rankings
The iSpring RCC7AK-UV is a 7-stage under-sink reverse osmosis system that combines mechanical filtration with alkaline remineralization and UV sterilization. It offers a high 75 GPD flow rate and NSF/ANSI 58 certification, making it ideal for well water users and larger households. The inclusion of UV sterilization is a standout feature, though it requires adequate feed water pressure.
The AquaTru Under Sink is a high-capacity reverse osmosis system designed for families, featuring a patented 4-stage filtration process that removes 84 contaminants without requiring electricity. It includes a dedicated faucet, a 3-gallon storage tank for on-demand access, and optional alkaline mineral boosting capabilities. However, the high wastewater ratio and requirement for professional installation are notable trade-offs.
