Description
The Crystal Quest SMART Filter Cartridge combines several filtration media in one replacement cartridge, so water passes through adsorption, catalytic chloramine reduction, redox, ion exchange and 1-micron particle filtration in a single pass. It is offered in four sizes and three levels, with published capacities from 10,000 to 300,000 gallons.
Highlights
- Coconut shell activated carbon and catalytic carbon reduce chlorine, chloramine, taste and odor
- ERA 6500 and ERA 9500 copper-zinc redox media target chlorine, ferrous iron and hydrogen sulfide
- Ion-exchange resin with selectivity for heavy metals, including lead and mercury at lower levels
- Also targets VOCs, THMs, pesticides, herbicides and pharmaceutical residues
- Plus, Ultra and Ultimate levels share the same flow rate per size, with higher capacity at each step
- Can serve as an RO pre-filter to protect the membrane from chlorine
Details
