Click on the chevron to the left of enlarge above to see scale comparison.Excessive scale is a challenge facing many homeowners, manufacturing and industrial water users around the world for decades. The build up of scale can cause damage or poor performance in hot water heathers, clothes and dishwashers, shower heads and other hot water using appliances/fixtures. This situation is compounded when water is ionized since the scale causing minerals are more concentrated and will have a tendency to create scale build up on the alkaline spout and connected parts. The traditional approach to hard water problems is sodium or potassium based ion exchange water softeners that waste water and dump high concentrations of salt into sewer systems and septic tanks. The EOS anti-scale device is an environmentally friendly way to reduce the amount of scale in your ionizer!
