AlkaViva Vesta GL Fluoride Shield Replacement Filter

For Filter Position 1 (left). Fluoride in drinking water is an unwanted contaminant for many of us. AlkaViva’s proprietary solution is the Fluoride Shield. It is NOT made of activated alumina or bone char and so is not pH or temperature-sensitive. It employs the latest cutting edge technology. The Fluoride Shield reduces fluoride to very low levels in laboratory testing. (Rated for 500 Gallons)
