As many of you know, beginning 1/1/2011 Enagic made a strategic decision to change the filter base on all their new Kangen Water machines such that neither their old filter cartridges or filter cartridges from any other company would fit in the machines sold from 1/1/2011. This move was clearly made as a response to the introduction of our American made cartridge filters which they know very well to be of superior quality. Otherwise they would not have made such a drastic move. Therefore if your Enagic Kangan Water Ionizer was made before 2011 you need to select a filter from the filters for machines made before 2011. Also be aware that if you have recently sent in your machine to Enagic for it to be serviced that Enagic can retrofit the filter base so that the older style filters do not fit. In that case you should select filters for machines made after 2010. We have both kinds of filters now and they are better quality than what you can get from Enagic.
