iSpring RO800G
Score: 75/100Rankings
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.
The iSpring RO800G is a tankless reverse osmosis under-sink water filtration system designed to deliver up to 800 gallons per day with a flow rate of 0.6 gallons per minute. It features a space-saving design that eliminates the need for a storage tank and offers a high water efficiency ratio of 2.5:1 pure to drain. The system is ideal for high-demand users needing rapid RO water such as large families, offices, or restaurants.
