Do all Water Ionizers have a carbon filter and why do some Carbon Filters have silver impregnation ?
All continuous flow Home Water Ionizers on the market have a carbon filter. The Regency Elite Water Ionizer comes with a silver impregnated carbon filter. The carbon in the Regency Elite filter is silver impregnated in order to retard bacterial growth. The silver that is impregnated in the carbon will NOT leach into the water. Every major manufacturer of carbon filters in the US & UK produces carbon filters with silver impregnation There are no Water Ionizers currently manufactured that use arsenic in their filters as has been suggested.
