Water travels through 7 stages of filtration:

• In stage 1, and 7  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, cyst (Giardia, Cryptosporidium), sand, rust, dirt, and other un-dissolved matter.

• In stage 2,  water travel through Nitrate-selective resin. Nitrate reduction is 90% to 95% and breakthrough is not affected by sulfate levels. The capacity is 3000 ppm of nitrates as CaCO3. To determine capacity, first, calculate the ppm of nitrates as CaCO3, then divide that number into 3000 to get the gallons. This cartridge can be regenerated using sodium chloride brine. 

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

• In stages 3 and 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.

• In stage 6,  water flows through granulated activated carbon (GAC). GAC is universally recognized and widely used as an effective adsorbent for a wide variety of organic contaminants, such as chlorine, chemicals linked to cancer (THM's, benzene) pesticides, herbicides, insecticides, volatile organic compounds (VOC's), 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, and these byproducts.

Important Note: The cartridge(s) in this system require manual salinity regeneration. The media must be recharged in order to maintain optimum performance. If the media is not regenerated, then the media will exhaust and result in a permeate of 0. The cycle of regeneration will vary based on the influent level of contaminants. The regeneration process should be done every 20 to 30 days depending on level of nitrate.

The process of regeneration involves dissolving salt in water (2-3 cups of salt for every 3-4 cups of water) stir well and soak (you may want to use something to hold the cartridge down) the cartridge for 1-2 hours, then soak the cartridge in tap water for an additional 1-2 hours, rinse with the tap running tap water and reinstall the cartridge. Regeneration is not required before its first use even if the cartridge has been unopened for a period of time.
