Fluoride Under Sink Water Filter System

15 reviews |



Leak Detector/Flood-Prevention Valve Included: Due to numerous unpredictable circumstances including installation errors, flood damage is subject to occur without a leak-detector valve. Our included leak detector/flood-prevention valve will allow the water system to be flood-proof.

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 Calcium 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.

    Could not beat Berkey

    I have purchased this under the sink system a few years ago and have been more than pleased ever since. The quality of the water beat Berkey in testing. Yes, I did buy a Berkey for emergencies and could not find the same quality when I tested the water. Aside from this, I could not tell you how helpful the customer service reps are. We ended up mixing up the order of the filters , never mind we were confusing their names and color (which is Smart, which was the Ultrafiltration, and so on) and we received step-by-step assistance RIGHT AWAY. So, thank you Crystalquest for the water quality you provide for my family and for always helping us to figure out the order of the filters while we are on our knees under the sink. We are also testing our water every 6 months or so and Crystalquest made sure to suggest and replace one of the cartridges to better fit the needs in the area we are living. Thank you!
