Combine a Black Ceramic Carbon Candle Water filter and a Stainless Bone Char Carbon Filter: You have the Ultimate Fluoride, Radiation & Heavy Metal Removal for Your Gravity Water System

Turn any DIY Bucket Gravity Water Filter System into a fluoride and radiation-killing powerhouse with the Stainless Fluoride Filter Add-On. This combination of Ceramic Filter and all-stainless-steel, (Exceeds NSF Standard) filter removes up to 99%% of fluoride without introducing Aluminum like Berkey, Doulton and many others. Removes arsenic, aluminum, lead, chromium-6, heavy metals and radioactive particles and ions—without sacrificing flow rate or adding plastic taste.

Perfect for preppers, homesteaders, and families who demand the cleanest possible water when the tap stops running or when municipal water quality can’t be trusted.

Why Add the Fluoride Filter to Your System?

  • .2 Micron Black Carbon Ceramic Filter: Removes Bacteria, Cysts, Giardia, Iron, and Particles down to .2 microns. .2 micron filter is 500 times smaller than a human hair to trap pathogens.
  • Maximum Contaminant Removal: Independently lab-tested to reduce fluoride below detectable levels (<0.01 ppm), plus 99.9% of lead, arsenic, mercury, chromium-6, radiation, and PFAS precursors.
  • Bone Char Post Filter: 100% 304 stainless steel housing—no BPA, no microplastics leaching into your drinking water.
  • Fast Flow Rate: Filters ~1 gallon in 12–15 minutes when paired with standard gravity elements (much faster than alumina (aluminum filters like Berkey) -only filters).
  • Long-Lasting Performance: Single filter lasts up to 1,500 gallons (≈ 6 months for a family of 4) before replacement is needed.
  • Universal Fit: Sets directly into the lower chamber  lid of most  gravity systems.Just drill a hole in the lower water lid and slide into place. Includes everything needed for instant installation.
  • Easily refill the filter media like making a cup of coffee. Discard the old Bone Char, and pour in new media.
  • Exceeds NSF Certifications: NSF/ANSI 42 & 53 certified media.
