Score: 85/100Rankings
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.
The Express Water 10-Stage RO System is a comprehensive under-sink filtration solution with alkaline remineralization and NSF 58 certification. It includes a 4-gallon tank to compensate for its slow flow rate, making it suitable for families. However, it requires adequate cabinet space and sufficient water pressure to operate effectively.
