Water Travels Through 7 Stages of Filtration

  • In stages 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 flows through a FLUORIDE REMOVAL 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 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.*
  • In stage 4, water flows through ion exchange resins, reducing heavy metals such as lead, copper, aluminum, and water hardness.  Ceramic and Tourmaline balls to enhance the water and maintain a more alkaline pH. 
  • 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, 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. To read about the ERA® Oxidation/Reduction Process, click here.
  • 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 (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. To read about how GAC's work, click here
  • Easy to use and install on all standard sinks.
  • Please note: 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 be specified in order to progress through the order entry screen.

Dependable delivery and quality

Arrived as ordered, opened and verified the filter received, had drinkable water in 30 min. My second or third house with a Crystal Quest filter. I appreciate the selection available, the different setups available, and the price points.

Great Filter

Elaine was a huge help in helping me determine which filtering system would fit my needs. Highly recommend their fluoride filter.

Seems to do a good job

We've been using this undermount fluoride multi-stage filter for years through Crystal Quest. It seems to do a good job, but I'd like to see them post lab confirmed data on their website that this removes what the website says it will remove. I just have to go on trust that what they say is true because there is nothing I can find online with any lab test results. Our water does taste good until the filter starts to go. We live in S. Florida and have hard water, so our filters only tend to last about 3 months with just 2 people in the household. The price of these filters have gone up quite a bit in the 5 years or so we've been buying them. I would appreciate it if they would email me a coupon code to use on my next order for leaving this review! I've called the customer support over the years and have found them to be helpful. I do like that they are using charcoal in their filters rather than aluminium. Also the plastic is free of PVCs, which is good.
