STAGES 1 & 7 water water flows through pre and post one - micron filter pads (1 micron equals 1/25,000th of an inch), which remove suspended particles such as silt, sediment, sand, rust, dirt, and other un-dissolved matter.

STAGE 2 water travel through Arsenic-selective resin, designed specifically for reducing arsenic. Capacity 500 gallons, depends on the arsenic type & ppb of influent water.

STAGES 3 & 5 water flows through a bed of media made of a special high-purity alloy blend of two dissimilar metals - copper and zinc (ERA-6500, and ERA-9500). ERA-6500 and ERA-9500 are major advancements in water treatment technology that works on the electro-chemical and spontaneous-oxidation-reduction (Eagle Redox Alloy) principles. Chlorine is instantaneously and almost inexhaustibly oxidized.

STAGE 4 water flows through ion exchange resins, reducing heavy metals such as lead, copper, aluminum, and water hardness.

STAGE 6 water flows through granulated activated carbon (GAC). GAC is universally recognized & widely used as an effective adsorbent for a wide variety of organic contaminants, such as chlorine (99.9%), chemicals linked to cancer (THM's, benzene), PCB's, MTBE's and hundreds of other chemical contaminants that may be present in water causing bad taste and odors in your drinking water. All Crystal Quest GAC is a mixed blend of coconut shell and catalytic GAC to address both chlorine, chloramines.
