Score: 85/100Rankings

The iSpring RCC7P-AK is a 6-stage under-sink reverse osmosis system designed to remove over 1,000 contaminants while restoring beneficial minerals. It features a built-in electric booster pump that ensures high efficiency and consistent performance in homes with low incoming water pressure. This makes it a maximum performance option for households with suboptimal 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.
