Classic SMART Filtration + Fluoride Removal: Water travels through SEVEN stages of filtration Removes hundreds of contaminants from your drinking water, with additional specialized resin for fluoride removalSits on the counter and easily connects to any kitchen faucetA diverter valve switches between filtered and unfiltered waterUse for any countertop/faucet and helps remove the sediment thus enabling your filter to work more efficientlyFilters up to 1500 gallons of water before needing a new filter (typically over 12 months of consistent usage) Water Travels Through SEVEN Stages of Filtration STAGES 1 & 7: water flows through pre and post one - micron filter pad (1 micron equals 1/25,000th of an inch), which removes suspended particles such as silt, sediment, sand, rust, dirt, and other un-dissolved matter. STAGE 2: water flows through a FLUORIDE REMOVAL media containing Fluoride Charcoal Granulated Activated Carbon (GAC). This media is specifically designed to have a high affinity for Fluoride, Lead and Arsenic. It removes metals through a mixture of adsorption and chemical reaction with the media; therefore, the elimination is not reliant on ion exchange. It has uniform particle size, is physically stable and can be used over a wide pH range. 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, 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.
