The ROTL-600 matches the ROTL-AIO on output and beats it on efficiency, delivering 600 gallons per day at a one-to-one pure-to-drain ratio that no other APEC system approaches. Its strongest attribute is that ratio, which halves the water bill impact against the all-in-one model and cuts it by two thirds against the tank systems. Its weakest is that it does so with three stages rather than four, so the pre-treatment path is shorter than anything else in the range at any price. It is also 300 dollars more than the ROTL-AIO for that trade, and neither model carries any certification. The buyer paying twice the price for the more efficient and less filtered of two otherwise similar systems is making a water-conservation decision rather than a filtration one.
