The Contour and the Classic are entry-level instant hot water dispensers from InSinkErator. They feature an upgraded hot-water stainless-steel tank, offering longer life and better performance. A more robust optional filtration system is available and includes the F-1000S and F-2000S filtration systems. The F-1000S reduces chlorine, taste and odor, while the F-2000S removes cysts, lead, mercury, asbestos, benzene and atrazine. The Contour and the Classic have an automatic shutoff and instantly dispense 200° F, near-boiling water.
