A drinking water RO unit has an in-line carbon filter as the post filter to remove any abnormal tastes or odors. It normally comes with a pressurized storage tank and a RO faucet. They reduce the TDS down low enough for safe drinking water levels, but are not completely free of TDS. fish tank only are RODI systems and provide 0 TDS water reading. and do not come with any tanks or faucet. but i guess its all the same, it's much better then tap water ;p
