Score: 85/100Rankings
The Waterdrop G3P600 is a tankless, under-sink reverse osmosis system featuring 8-stage filtration and a smart display faucet with real-time TDS monitoring. It delivers a high flow rate of 600 gallons per day with a water-efficient 2:1 pure-to-drain ratio, designed to save space and reduce wastewater. Best suited for households of 5-7 people needing reliable daily filtered water supply.
The APEC ROES-50 Essence is a budget-friendly 5-stage under-sink reverse osmosis system designed for DIY installation, producing 50 gallons of purified water daily. It features a 4-gallon storage tank and utilizes a FILMTEC membrane to remove up to 99% of contaminants, including lead, arsenic, and PFAS. However, experts note its high wastewater ratio and lack of full NSF/ANSI 58 certification compared to newer, more efficient models.
