About
Delta Clarifi™ Tankless Reverse Osmosis System is a compact, powered, under-sink RO unit that pushes tap water through a six-stage membrane–carbon train, achieving high recovery (≈78 %) without a storage tank. Independent, NSF-certified tests show broad contaminant removal—including micro- and nanometre-scale particulates—while an optional remineraliser can add back healthy minerals.
