How to Filter Fluoride

Reverse Osmosis (RO) - Reverse Osmosis is one of the most effective ways to filter fluoride. It is a very good choice for under-sink applications. It can be used in a whole house, point of entry application but does require a storage tank and alkalizer. These increase costs and installation complexity. Bone Char is often the better choice for whole house. The negatives of RO are wastewater and loss of healthy, beneficial minerals. We do offer an alkalizer cartridge add on to add those healthy minerals back in.

Bone Char – Bone Char is a very effective medium for filtering fluoride. It is best used in Pitcher, countertop, under sink and whole house applications. Unlike RO, it retains healthy, natural minerals and does not produce wastewater. Bone Char is created by treating animal bones with very high temperatures. This creates a carbon media that is very good at absorbing fluoride. This is the media we use in our fluoride filtration pitcher and systems that are not RO. Unless Activated Aluminum Oxide is requested.

Aluminum Oxide – Aluminum Oxide will work in the same applications as Bone Char. Countertop, under sink and whole house applications. Most of our systems use Bone Char, if you prefer aluminum oxide please contact us to request it. It is a high-capacity synthetic adsorbent media that is highly selective of Fluoride, Arsenic, and Lead. The media is a synthetic aluminum oxide that is specifically processed to have a minimum of fines and other foreign matter. It removes metals through a combination of adsorption and chemical reaction with the media; therefore, the removal is not dependent on ion exchange.

Distillation – Distillation is only for countertop use. Water is boiled to steam; fluoride (non-volatile) and most minerals stay behind in the boiling chamber. The steam condenses to (very) low-mineral water. It is very effective at removing fluoride but requires lots of energy and time. It results in water without minerals and many not be recommended to drink over time due to this complete lack of minerals.

Fluoride is a substance that is highly toxic to humans. Studies have shown that varying levels of fluoride ingested can damage the brain, cause dental fluorosis and negatively affect other systems in the body.

There are two ways fluoride could end up in your water.

If you have well water, naturally occurring fluoride could be in your well. It is very important to test. Fluoride levels above 1 mg/L can have negative health effects and filtration is needed.

If you are on city water, your water utility may add fluoride in a process called fluoridation. This is done in an effort to prevent tooth decay. Although fluoridation levels are relatively low at 0.7-1 mg/L, this is forced medication without dose control for the individual. People who drink more water, drink tea (boiling condenses the amount of fluoride), pregnant women and children are at a higher risk of unhealthy levels of fluoride due to fluoridation. If you, or your family is in this risk category, or you just don’t want to be drinking something toxic added to your water you should purchase a fluoride filter.

Yes, most of our systems combine fluoride filtration technology with other filtration methods. These will filter a wide range of contaminants including chlorine, heavy metals, PFAS, and many other contaminants.

We do have systems that filter only fluoride. This will be clear in the description. These are best if you already have water filtration and want to add fluoride filtration to your set up.

For decades, water fluoridation in community water systems has been a controversial public health policy, with critics arguing that it poses a serious potential risk to overall health, with many advocates demanding communities stop adding fluoride, as well as remove fluoride altogether. Now, scrutiny of fluoride practices has grown to a fever pitch as more scientific weight is added to its long-term health risks.

As high-profile opposition, legal battles, and state-level actions converge, Utah & Florida have ended fluoridation. Many small communities have ended fluoridation as well.

The majority of our fluoride filters have a filter life of 6 months–1 year. This can vary depending on water use, quality and the system you have. Please go to the product page of each system and look for the tab “replacement schedule” It will show the exact filters you need and when to expect to replace them. We will send a reminder email for most systems when they are due. You can also contact us via live chat or email and we will let you know exactly what you need and when you need it.

The standard water filter inside your fridge does not filter fluoride. It will filter chlorine, heavy metals, and other contaminants, but not fluoride. We offer refrigerator fluoride filters that work with your existing fridge filter. They install inline, along the cold-water line that goes to your refrigerator allowing you to have fluoride-free ice and water. Installation can be behind your fridge, anywhere along that water line, inside a cupboard, or in the basement below the fridge.

Our Smart Fluoride Pitcher Water Filter is the most inexpensive way to filter fluoride. It is a convenient pitcher that fits in your fridge and does not require installation. It utilizes bone char to filter fluoride combined with our smart media to filter chlorine, PFAs, pesticides and many other contaminants.
