Ultimate Fluoride II Drinking Filter System

Dual-cartridge drinking water filter for countertop or under-sink installation. Made in the USA.

The Ultimate Fluoride II pairs a dedicated fluoride-reduction pre-filter with a 1-micron catalytic carbon block, built to reduce fluoride along with chloramine, chlorine, and a wide range of other contaminants. It connects to your cold water line under the kitchen sink and delivers filtered water through an elegant, long-reach, lead-free dedicated faucet with a washer-less ceramic valve. Countertop and under-counter configurations are both available, so you can keep the system out of the way and your counter clear.

Why filter fluoride

Fluoride has long been added to public drinking water for dental health, and the science on ingested fluoride at higher exposure levels has advanced considerably. If you prefer to reduce the fluoride in your tap water, the current research gives you solid ground to stand on.

• Federal review (2024): The U.S. National Toxicology Program completed a systematic review of fluoride and brain development. It concluded, with moderate confidence, that higher fluoride exposures (drinking water above the World Health Organization guideline of 1.5 mg/L) are consistently associated with lower IQ in children. The review did not address fluoride levels typical of optimally fluoridated U.S. water, and noted more research is needed at lower exposures.
• Federal court ruling (September 2024): A U.S. District Court ordered the EPA to take regulatory action, finding that fluoride in drinking water at current U.S. levels poses an “unreasonable risk” to children’s health. The court was clear it did not conclude with certainty that fluoridated water is harmful, only that the potential risk is high enough to require the EPA to respond.
• A matter of choice: Naturally occurring fluoride is present in some water as calcium fluoride. Fluoride added to municipal supplies is typically introduced as a fluorosilicate compound. Reducing what reaches your glass is a reasonable personal choice, and the Ultimate Fluoride II is designed to do exactly that.

The Ultimate Fluoride II is a water filtration device. It is not a medical device and is not intended to diagnose, treat, cure, or prevent any disease.

8 stages of filtration

The dual-cartridge system runs water through eight filtration stages, built to significantly reduce fluoride, chloramine and chlorine, VOCs (volatile organic compounds), THMs (trihalomethanes), lead and other heavy metals, parasites such as cryptosporidium and giardia, and particulates including asbestos.

Cartridge #1: Fluoride Pre-Filtration

• Stage 1: 100-micron reticulated poly foam (filters particles roughly the size of a human hair)
• Stage 2: 550 grams of pre-conditioned fine-mesh activated alumina (designed to reduce fluoride to below 0.5 ppm)
• Stage 3: High-efficiency GAC (granular activated coconut shell carbon) for the reduction of chlorine, taste, and odor
• Stage 4: 20-micron spun-bonded polypropylene (filters particulates about one-quarter the size of a human hair)

Cartridge #2: 1-Micron Compressed Catalytic Carbon Block

• Stage 1: Protective polypropylene netting (large particles: dirt, sediment, rust)
• Stage 2: 15-micron bonded polypropylene layer (medium-size particles)
• Stage 3: 5-micron melt-blown polypropylene layer (fine particles)
• Stage 4: Catalytic carbon block compressed to a 1-micron pore size with radial filtration. This design prevents channeling or bypass and is proven to reduce or eliminate chloramine and chlorine along with their associated THMs and VOCs, lead and heavy metals, micro-organisms (giardia and cryptosporidium), and particles larger than 1 micron.

What customers say

"I'm so glad I purchased this water filter. I had been drinking distilled water in plastic jugs because I wanted to make sure I wasn't getting any fluoride or other contaminants, but now that I'm trying to avoid plastic I needed another solution. After much shopping around I chose this one because of the 30-day money-back guarantee and free shipping. The water tastes amazing, very clean and pure. The countertop model was super easy to install, which is a huge bonus because neither my husband nor I are good with installing things. I absolutely love it and will be recommending it to my friends and family."
