We live in an area where the water quality is horrible. The local water supply has way too much lead and sodium. The ZEROWATER filters are the only one that can handle these contaminates. We've had our Readypour for over two years and it has been perfect. It fits nicely in our refrigerator and eliminates the need to buy bottled water every week. It couldn't be more convenient. PS, We're also keeping a lot of plastic out of the landfill, and that's a great thing.
