Description
The Crystal Quest Nitrate Removal + SMART Single Cartridge Countertop Water Filter System reduces nitrate by 90% to 95%, with breakthrough unaffected by sulfate levels, using a nitrate-selective resin cartridge rated for 3,000 ppm of nitrates as CaCO3.
Highlights
- 7-stage filtration: pre/post 1-micron filter pads remove suspended particles such as silt, sediment, cysts (Giardia, Cryptosporidium), sand, rust, and dirt
- Nitrate-selective resin reduces nitrate 90–95%, with a capacity of 3,000 ppm of nitrates as CaCO3; cartridge is regenerable with sodium chloride brine (recommended every 20–30 days depending on nitrate level)
- Ion exchange resins reduce heavy metals such as lead, copper, aluminum, and water hardness
- Eagle Redox Alloy media (ERA-6500 & ERA-9500) oxidize chlorine through an electrochemical, spontaneous-oxidation-reduction process
- Granulated activated carbon (a coconut shell and catalytic GAC blend) adsorbs chlorine, chloramine byproducts, pesticides, herbicides, VOCs, and other organic contaminants affecting taste and odor
- Diverter valve switches between filtered and unfiltered water; white polypropylene housing is BPA free
