Use Coupon Code Membrane10 to get a 10% discount on our already low-priced RO elements (with a $50+ purchase). Why are "RO Membranes" referred to as "RO Elements?" As shown in the graphic below, the semi-permeable RO membrane is only one of multiple layers in each leaf of a spiral wound Element. "Element" is a more technically-correct way to refer to the entire product, including all leaves, the central stem, outer wrapper, brine seal, orings, etc.
Regardless - our residential RO membranes/elements are on sale - come get some!
