The BioStone Plus filter for the Vesta is for use in Vesta ionizers only. The carbon block, fiber filters, calcium, and tourmaline combine to provide a revolutionary filter performance. The filter improves water taste and reduces odors. It is particularly effective in removing chlorine.
(Important Note: This filter is a different size than the regular BioStone Plus and cannot be used in any ionizer other than the Vesta).
Sediment OR Fluoride goes on left side - the Vesta Biostone Plus goes on right side.
