Platinum is used because it is an excellent conductor. The Technos does NOT use stainless steel electrodes as has been suggested by other companies. Stainless steel was used for Water Ionizer electrodes in the late 1980's and was found not be a suitable material because they did not last more than a a few years. The industry began using titanium platinum-coated electrodes as a whole in the early 1990's because it will last indefinitely. At present, no one is manufacturing Water Ionizers with stainless steel electrodes.
Some companies claim to have solid platinum electrodes on their water ionizers.
Solid platinum electrodes would be cost prohibitive to begin with. The electrodes are one of the most expensive components of the water ionizer. Anyone claiming to have solid platinum electrodes in the water ionizers they are selling do not know their own product because solid platinum electrodes are, in a practical sense, not possible in a water ionizer. The Technos comes with a one year warranty from the date of purchase. If anything goes wrong with the unit during that period, return it to the Watershed and it will either be repaired or replaced, if necessary, for free as long as it is under the warranty.
