SKU: 3K-FC-RN Category:


This is a 3-canister radiation water filter in the undercounter version, that also filters fluoride, chloramines, chlorine, and hundreds of other organic and chemical contaminants, plus heavy metals and odor and taste issue.


This is the best if you want to filter radiation, chloramine, and fluoride plus hundreds of other contaminants.

The radiation water filter cartridge will remove any type of ionic radioactive contaminant including Uranium, Plutonium and other heavy metal.

The housing is tested to handle 100 psi, a 33.3% increase in pressure above standard undercounter white filter housings.

WHAT IS FILTERED?  (short sample list) 

* fluoride

* chlorine
* chloramine
* radiated iodine
* strontium
* cesium
* plutonium
* uranium
* all other radiated cationic and anionic isotopes
* disinfection by-products like trihalomethane
* perchlorate
* mtbe
* heavy metal
* chromium
* lead
* sediment
* algae
* molds
* scale
* bad taste
* pesticides
* hormones
* pharmaceuticals
* odors

The FDA has certified kdf as releasing nothing harmful into the water. The EPA has certified kdf as compliant with Standards 61 & 42.

Water flows over and through several filter media designed to remove fluoride, chloramine, radiation and a very wide range of contaminants. Different filter media select for targeting contaminants.

There are 6 sediment stages and 7 different types of media, in 7 other layers, using multiple filtration methods. The types of filtration include ‘pore opening’, magnetic attraction, catalytic action using reduction-oxidation, electroplating, ANION AND CATION ION EXCHANGE, reshaping of hardness ions and adsorption. An environment harmful to bacteria, algae and fungus is created. The water acts softer.

Trace elements the body needs stay in the water!

Water flow is excellent.

This unit contains:

* FIRST CARTRIDGE: A sediment filter and a full pound and half of activated alumina to remove fluoride. (This is not aluminum.) …….. OR you can select calcium-based carbon to filter fluoride.  The effectiveness is equivalent.

* SECOND CARTRIDGE targets radiation. Sediment filters are between each of the other media. First granulated activated carbon which filters a wide range of radiation contamination; then media to focus on strontium and cesium; then a media bed of combined cationic and anionic resins to filter the range of radiated isotopes, and finally another layer of carbon to further filter and polish the water.


– Sediment filters at start and finish

– Kdf 85 – 1 1/4 pounds! Especially effective at filtering chloramine, chemically-based contaminants and heavy metals. Works on radiated iodine. Kdf is bacteriostatic, preventing bacteria from growing in the carbon or your water.


– Granulated Catalytic Carbon – a full pound (that’s 453 grams) of top-grade pre-washed granulated catalytic carbon! Works especially well against organic-based contaminants and further filters radiation. Best carbon for mtbe.

The fixtures are the highest quality, and there is more of the right filter material – resulting in greater and longer-lasting filtration. THAT IS HOW FILTERING HAPPENS!


Everything you need!

* One fluoride filter cartridge   Change every six months.  Select Activated Alumina or Calcium Carbon (bone char.)              We don’t recommend one over the other.
* One radiation filter cartridge (RN-1)    Change once a year in low-radiation circumstances, more often if needed.
* One chloramine-focused, wide spectrum cartridge (CR-1) cartridge   Change once a year
* Plastic wrench to make changing cartridges easier
* Faucet and parts needed to install


* Select Activated Alumina or Calcium-based Carbon to filter fluoride.  They both work well – it’s your choice.

* Get a free standard faucet or upgrade to a better and more attractive faucet.  We recommend the upgrade. 


* The size of the unit is 17.5 X 6.5 X 14.5″.

    I did quite a bit of research for kitchen filters and felt this was the best option. I ended up attaching it to the water line of my refrigerator so I could have cold filtered water and my ice maker would be filtered as well. Plus, I would no longer need to use the refrigerator filter which needed replaced twice a year. I chose radiation because I was tested by my doctor for chemicals and it showed I had a high level of strontium. My doctor recommended I filter my drinking water. The install was easy (although the fittings and water lines included with this model don’t work on the fridge because much longer lines are needed, as well as adapters to switch from the filters 3/8″ fittings/line to the fridges 1/4″ fittings/lines. A little thinking with the help of and I figured it out. I also installed a shutoff valve right before the filter since I store the canisters in a cabinet above my fridge and will need to easily turn the water off when I make filter changes.(without moving the fridge to turn off water line from wall). So installing that’s easily reached made sense. I chose fluoride as my second filter. And then the chloramines filter for the final since my water supply contains chloramines, not chlorine. Water tastes great. Water pressure and flow did not change. I will only need to change fluoride filter at 6 months and other 2 yearly. Overall very happy with product. I also spoke with Timothy twice with questions and he patiently answered every question. I feel Friends of Water is a very reputable company and will help the customer in any way they can.

      Hi Shane, thank you so much for taking the time to share your experience and impressions. For most folks, we recommend getting a plumber for kitchen and fridge filters. But as you note, if you have the skills, you can do it yourself. Best to you.
