2015 H2O Innovations 300gph RO. Ran only about four hours and about 1,200 gallons of sap through it this spring. Might as well be new but without full retail price or sales taxes! This machine is mint. Super easy to use. Incredible time and cost saver versus boiling raw sap. Comes with a five gallon wash tank and three pvc storage vessels.
