Product review (5 stars): Fuss free, complete unit that's ready to use in minutes.
Rural Kansas water is nasty. This little system delivered clean, great-tasting drinking water with just a quick connection to the faucet. Totally portable so we can use it when we travel. The Itty Bitty CounterTop CT-10 lists a capacity of 1500 Gallon so I'm guessing it should be good for about a year.
