    1. A Crystal Quest® WS Fluoride Under Sink Water Filter System-Single

    2. A PDF e-book about the benefits of filtering water. It covers the history of water filters, the reasons why you should filter your water and the various filtration methods. $39.00 value.

    Our Fluoride Under Sink Water Filter System reduces or removes contaminants such as chlorine, heavy metals, and fluoride from tap water to offer the freshest taste to you. This system is the perfect solution for any household. It is quick and easy to install and use, attractive, and convenient.

    • Installs neatly under the sink.
    • Comes with a beautiful faucet and all necessary installation hardware

      When considering installation, if current under sink plumbing is hard copper tubing the saddle valve would be used; for flex tubing, the T-valve would be required. While ordering a prompt will require that an installation valve is specified in order to progress through the order entry screen.

      Fluoride Water Filter Cartridge

      Water flows through a fluoride removal water filter cartridge containing Fluoride Charcoal Granulated Activated Carbon (GAC) unless Aluminum Oxide is requested. 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 a uniform particle size, is physically stable and can be used over a wide pH range. Capacity: 4500 ppm Fluoride (Avg. 1000 to 1500 Gallons). As high as 11000 ppm F+ with effluent levels below 0.2 ppm from 10 ppm F+ feed.

      SMART Water Filter Cartridge

      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 electrochemical and spontaneous-oxidation-reduction (Eagle Redox Alloy®) principles. Chlorine is instantaneously and almost inexhaustibly oxidized.

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

      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 (99.9%), 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.

      Carbon Block Water Filter Cartridge

      Water travels through a 5-micron solid carbon cartridge for removing volatile organic carbon compounds (VOC's), insecticides, pesticides and industrial solvents and traps particles larger than 5 microns including sediment, silt, sand, and dirt.

      Ask a Question
      • How often do you have to repurchase a whole new kit or can you just wash the canisters and replace the filters as they state? Ours tastes like it has algae or mold in it. We just replaced the filters six months ago and washed everything

        Our products are designed to last, so you should not have to repurchase a whole new system. Acidic water can cause things to leech off pipes, scale build-up, or an algae/mold taste. Often times if you switch the position of the Carbon Block Filter from the front to the end you can see a change in taste of your water. In rare cases, the Fluoride and SMART can create a bad taste from the media interacting with each other. It should decrease over time. Other methods for cleaning the canisters is to use either a 50/50 mixture of hydrogen peroxide and water or white distilled vinegar and water, let soak overnight. Wipe down with a warm cloth and reassemble your system. I hope this works for you, please feel free to reach out if you need further assistance.

      • Does this get rid of PFOA's? Are the filters NSF certified?

        Yes, it does. The granulated coconut shell, granulated activated carbon, and catalytic granulated activated carbon both target PFOA's All components and media are NSF certified. We rely on the components and media certification for all of our products.

      • How often do we change the fluoride under sink filter and how often do we change the smart under sink filter?

        We recommend anywhere from 12-24 months, depending on consumption and water condition. On average 12-18 months is a good number to go by. This applies to both filters.
