Which Water Filter Removes Fluoride from Water

Which Water Filter Removes Fluoride from Water? 

Fluoride is among the most common elements present in municipal and city water supplies. Unfortunately, we can’t control the amounts of fluoride present in our water source. Buying a water filter system will make your water cleaner and ensure you’re not consuming excess fluoride.

However, choosing the ideal fluoride water filter can be challenging due to the different options available on the market. We’ve tested several systems and reviewed which water filter removes fluoride most efficiently. Read on to find the best option.

What Is Fluoride? 

Fluoride is a natural mineral found in rocks, water, air, plants, and soil. It’s also synthetically produced for use in mouthwashes, toothpaste, drinking water, and several chemical products.

How Does Fluoride Get Into Your Drinking Water? 

Many countries add fluoride to public water supplies due to its ability to protect against tooth decay and improve your overall dental health. It does this in two ways: mineralizing the teeth and preventing bacterial overgrowth. As a result, public water supply is often the major fluoride source for low-income populations.

The quandary is that studies have shown that excess water fluoridation can cause varying health issues.

Possible Side Effects of Fluoride

Excess levels of fluoride can result in different effects depending on the quantity and extent of exposure. Fluoridated water increases your risk of developing bone fractures and osteoporosis. Other possible effects of excess fluoride:

Bone Fragility

Excess fluoride can result in a rare condition known as skeletal fluorosis, which is characterized by stiffness or hardening of the joints, as well as fragile bones.

Acute Fluoride Toxicity

Too much fluoride can lead to acute toxicity. Common signs include vomiting, stomach upset, diarrhea, and nausea. The effects can be life-threatening, especially for young children.

Dental Fluorosis

Dental Fluorosis manifests with white streaks or white spots on the teeth. It can affect your child if he or she is exposed to high levels of fluoride while their teeth are still developing. Note that fluorosis isn’t harmful to the teeth, but it can be a cosmetic concern.

So, Which Water Filter Removes Fluoride Best?

In this buying guide, we’ll compare the five best water filters that remove fluoride. These water filtration systems don’t only remove fluoride, but kick it up a notch by removing other contaminants from your tap water.

Let’s take a look at our top picks.

5. Alkanatur Alkaline Water Filter Pitcher

The Alkanatur Alkaline Water Filter Pitcher is a water filter unit that purifies drinking water, removing its alkaline content. The outstanding feature of the Alkanatur Alkaline Water Filter Pitcher is that it does not add sodium to water while filtering.

It has the pride of being the only alkaline filter that does that. By evading the use of the ion exchange resin process in the purification of water, it avoids health risks caused by the presence of sodium.

Magnesium, an element required in the body for protein synthesis and other biochemical reactions, is added to the water purified with an Alkanatur Alkaline Water Filter (about 18mg per liter). The filter, however, retains potassium.

Additionally, since it ionizes the water it purifies, the water serves as an antioxidant with oxidant capacity up to 77.7%. Radicals up to -350 ORP are roundly eliminated. The ensuing water from the filter is light with a PH rating of about 8.5 to 9.5.

The filter is made free from bisphenol A(BPA), an industrial chemical employed in the production of polycarbonate plastics and resins. Its presence in the body affects the endocrine system and increases the possibility of developing type 2 diabetes. Alkanatur Alkaline Water Filter is also free from cell-binding inhibitors like the bisphenol FL (Fluorene-9-bisphenol, BHPF).

The filter element, like that of several other filter units, is made of coconut-activated carbon. The pitcher is very convenient. It can be used to serve outdoor events with no concerns about weight since it’s made of light plastic.

Aside from being light, you can easily maintain the Alkanatur Alkaline Water Filter with no technical expertise. The units can be dispatched while replacing the filter and easily coupled back together.

Manufacturers recommend that the filter be changed after every 400 liters of water is purified — this is not definitive, though. Users who regularly use the filter system should replace the filter more frequently.
