For Athena and Melody ionizers with 2 filters.
The BioStone Plus paired with our Sediment filter.
The BioStone Plus starts with the same compressed carbon block as the Basic, then we add Plus technology by impregnating it with specialty media to increase contaminant reduction.
It removes more Chloramine, heavy metals and other tough contaminants than the BioStone Basic, but not as many as the Ultrawater filter.
Containing Scale Guard protection, it will out perform any GAC filter – regardless of micron rating. (Rated for 1000 gals.)
(BioStone Plus rated for 1000 Gals)
The Sediment is used in Filter Position 1 (on the left as you face the front of the ionizer) and utilizes an advanced spun fiber technology to safeguard your Athena and enhance the life of whatever you have in Filter Position 2.
