Water is an essential component of daily life, and it is crucial that the water we consume is clean, safe, and pleasant to use. Unfortunately, many people face the issue of hard water in their homes. Hard water is water that contains high levels of minerals like calcium and magnesium, which can cause a range of issues, including soap scum, dingy clothes, and clogged pipes. 

 According to a report published by the Spanish Ministry for the Ecological Transition and Demographic Challenge in 2019, the water hardness in various regions of Spain ranges from 100 mg/L to over 400 mg/L of calcium carbonate (CaCO3). Some examples of water hardness in different cities in Spain include: Madrid: 250-300 mg/L CaCO3; Barcelona: 170-260 mg/L CaCO3; Valencia: 200-300 mg/L CaCO3; Seville: 250-300 mg/L CaCO3; and Malaga: 180-220 mg/L CaCO3. It's worth noting that some regions in Spain have higher water hardness than others, and the exact water hardness may also vary depending on the time of year and other factors. Water hardness can impact the taste and quality of tap water, and may also affect the performance and lifespan of household appliances that use water, such as coffee machines or washing machines.

Biocera Antioxidant Alkaline Water Filter uses Biocera Balls (ceramic beads) in the filter medium that is designed to increase the pH of the water and add alkaline minerals such as calcium, magnesium, potassium, and sodium. Moreover, the ceramic beads generate abundant hydrogen which helps to neutralize free radicals and reduce oxidative stress in the body. The Biocera Balls were initially developed by Dr. JEON Hyoung-Tag in the 1990s through crystal growth technology.
