Description
This Crystal Quest replacement cartridge refits the Bath Ball filter with ERA-6500 and ERA-9500 redox media for chlorine reduction at a flow rate of 4 to 5 GPM. Crystal Quest estimates 12 to 18 months of use per cartridge at water hardness under 100 ppm.
Highlights
- ERA-6500 and ERA-9500 media reduce chlorine and chloramines in bath water
- Also targets hydrogen sulfide (rotten egg odor), iron oxides, sediment and other odors
- 4 to 5 GPM flow rate keeps bath fill times practical
- Reversible disk design: flipping it periodically balances filtration and extends disk life
- Sold singly or in packs of 2, 4 or 6
