The BioStone Plus is used in Filter Position 2 (right). The mid range filter is designed with compressed carbon block and is enriched with Plus Technology, by adding specialty media to to the carbon block to increase contaminant reduction. It removes Chloramine, heavy metals and other tough contaminants better than the BioStone Basic. Will not remove heavy metals as well as the UltraWater filter does. Containing Scale Guard protection, it will outperform any GAC filter – regardless of micron rating.
Vesta GL Fluoride Shield Filter (position 1- left) is a cutting-edge water filtration system designed specifically for Vesta H2 series. Unlike other filters utilizing activated alumina or bone char, Fluoride Shield is not affected by pH or temperature. By using advanced technology, it effectively reduces fluoride to very low levels, as shown in laboratory testing.
