1. Introduction to Fluoride in Water
Fluoride occurs naturally in groundwater and is also added to municipal supplies for dental health. However, excessive exposure can lead to fluorosis, bone weakness, and other chronic conditions. The World Health Organization (WHO) recommends that fluoride levels should not exceed 1.5 mg/L in drinking water.
To achieve optimal safety and taste, homeowners and industries turn to fluoride water filters designed with specialized filtration technologies such as activated alumina, reverse osmosis, and bone char carbon.
2. How Fluoride Water Filters Work
Fluoride removal requires specialized media that target fluoride ions in water. Here are the main technologies used:
- Activated Alumina (AA): A porous aluminum oxide that adsorbs fluoride efficiently, often reducing up to 95% of fluoride content.
- Bone Char Carbon: Made from charred animal bones, it removes fluoride, heavy metals, and chlorine effectively.
- Reverse Osmosis (RO): Uses a semi-permeable membrane to remove up to 98% of dissolved solids, including fluoride.
- Deionization and Distillation: These methods physically separate contaminants, leaving behind ultra-pure water.
