Another Great Emco Tech Advantage-
The Biostone and Ultra-Biostone Filters

The Emco Tech quality extends to the revolutionary Biostone filters.

* The activated carbon in the filter comes from the UK and is NSF certified
*The natural mineral calcium in the filter comes from Japan and is certified by the Japanese Government.
*The Ceramic Biostone in the filter is produced in Korea and comes with Korean FDA certification.
*Finally all ingredients are put into the filter housing where sealing is achieved by using high motion heat friction thereby avoiding the need for any harmful chemicals.

Biostone .1 Micron (.1M) granulated, silver-impregnated carbon filter

The Biostone has nine separate stages of filtration. To give you an idea of how fine these filters are - there is over 25,000 microns in one inch. There are 250,000 .1M in one inch.

The primary filtering media is Granulated Activated Carbon. There is silver impregnated into the carbon to make sure that bacteria does not grow. Because it is impregnated into the carbon, the silver does not leach into the water. Tests done by the Seoul Department of Health show that no silver is released from these filters.

The Biostone Filter also includes five fiber layers. These layers provide extra effectiveness. The Biostone also includes calcium plus a layer of Bioceramic Tourmaline. The coral calcium is Japanese premium grade and comes from environmentally approved land deposits. The coral calcium not only helps to slightly remineralize the water but also naturally sweetens the water and changes volatile fluorine molecules into a benign compound (calcium fluoride).
The tourmaline in this patented, state-of-the-art filter really makes a difference to the ability of the water to carry an ionized charge naturally. As the water passes over the tourmaline crystals the ORP is naturally decreased and the water made more bio-available. What this means is when water passes through your Athena or Delphi even in “Purified” mode the water will come out slightly ionized!
Biostone .01 Micron hollow membrane / carbon filter
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.

Typically, if on city water we recommend the regular Biostone filter but for well or other untreated water and where there is hyper-allergy issues we recommend the .01M Biostone filter. The picture above 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 the filter is the same as the .1m Biostone – 4 fiber filters, silver impregnated Granulated Activated Carbon, Calcium and Bioceramic Tourmaline.
