Reduction of Contaminants: Samsung Electronics water filters use only a high-grade carbon block which removes over 99% of the potentially harmful contaminants that may be present in your water, including: • Chlorine Taste & Odor: Chlorine is used widely to treat water but may add a particular taste and odor to the water • Heavy Metals & Chemicals: Lead, asbestos, benzene, mercury and carbofuran; these common industrial contaminants with high toxicities can infiltrate the water source and be potentially harmful to your health • Microbial Cysts: Parasites such as cryptosporidium are commonly found in lakes and rivers. They have a high resistance over disinfectants such as chlorine and thus may be present even in treated water.
