Voted  “best buy” by Consumers Digest five years in a row, theAquasana system uses a combination of carbon filtration, ion exchange and sub micron filtration to produce safe water for less than ten cents per gallon. That’s right ten cents a gallon! Compare that with bottled water!  Right now there is a “huge” trend towards consumers purchasing these filters. The awareness of the contaminants in water, plus the knowledge of what the effects of purchasing and disposing of billions of plastic water bottles have made this move a smart consumer choice. We purchased ours and are enjoying clean water every day!
