With a family of seven in a third floor apartment, the last thing I wanted to do was not only purchase all of that bottled water and all of those plastic bottles, but carry all the water up to the third floor!  I found ZeroWater and now I tell all of the people who will listen how amazing this company is.  For a family of seven we go through about a filter ever two weeks, so I order in bulk on the website and we can send them back in the same packaging to recycle the filters!  Win for us, win for the environment, win for not having to carry bottled water!  Love it!
