This is an optional upgrade filter available for the
Athena and Delphi
. Also called a hollow membrane filter this filter is the same size filter that is used in kidney dialysis. It is the finest (smallest micron) domestic filter available and will remove virtually everything except for the essential alkalizing minerals.
For well or other untreated water and where there is hyper-allergy issues we recommend the .01M Biostone filter.
The picture to the right shows a single .01M hollow membrane filter fiber
magnified 40 times
. Hundreds of these are in a Biostone Ultra Filter.
Below the hollow membrane stage of the filter is 4 fiber filters, silver impregnated Granulated Activated Carbon, Calcium and Bioceramic Tourmaline.
