NSF 61 certified granular activated alumina for fluoride and arsenic removal from drinking water. Activated alumina (AA) is the only filter material specifically designed to remove fluoride and arsenic from water. It is a ceramic compound made of aluminium oxide with a very high surface-area-to-weight ratio, AA has a very high capacity for fluoride adsorption. Most municipal water supplies add 2 ppm (parts per million) of fluoride. AA filters can reduce fluoride concentrations to below 0.1 ppm, in other words 99% of the normal fluoridated water level.
Available in 1-10 lb packages.
