Water filters not only remove contaminants, they can also make your water taste way better – think crisp and fresh.
Moreover, they provide you with an eco-friendly alternative so you can ditch wasteful single-use plastic bottles forever.
With that said, some people think that all water filters are alike and filter out the same contaminants. Well, that couldn’t be further from the truth.
Some water filters can screen out potentially harmful and toxic heavy metals, while others will only improve the taste of water slightly. Also, no filter or technology is 100% effective in removing all contaminants from tap or well water.
So, which type is suitable for fluoride removal? Do water filters even remove fluoride?
This short guide will walk you through various water filter options that can help you remove fluoride from your water supply.
Yes, you can filter fluoride from water using a water filter. However, it is essential to note that not all water filters feature the technology to remove the infamous salt. Furthermore, even those water filters that can reduce it have different reduction rates.
For example, some filters can remove 95% fluoride while others bring down the level by a mere 80%.
Fluoride is one of those impurities that are particularly hard to remove from water. However, installing a specialized filter can ensure that the water you bring in from the tap is pure.
In the era that we are living in, we have three methods through which we can have clean, fluoride-free water running through our household:
Fluoride reduction: About 95%
Reverse osmosis is highly effective at removing fluoride. Also, reverse osmosis systems are one of the most popular methods used for fluoride removal. That’s no surprise considering RO membranes offer meticulous filtration removing 99.9% of hundreds of water contaminants.
In an RO filter, a semi-permeable membrane filters out contaminants and impurities based on their size. Being rated at 0.0001 microns, an RO membrane rejects almost everything that’s larger than water molecules.
What’s more, RO systems feature multiple post and pre-filters that help improve the quality of your water even further.
The only problem: RO water purification also removes healthy minerals such as calcium, magnesium, potassium and sodium. What’s worse is that an RO filter wastes a lot of water. For instance, to deliver a single gallon of filtered water, a standard system easily sends three gallons down the drain.
#1 Reverse Osmosis System for Fluoride: AquaTru
Fluoride reduction: 90-95%
Bone char makes an excellent fluoride filter with a highly porous ionic surface that loves adsorbing impurities.
The lesser-known water filter technology is not commonly used but can reduce a wide range of contaminants, including fluoride, heavy metals, and radioactive elements.
Please keep in mind, bone char is not the same as activated carbon and is not similar to it either.
#1 Whole House Fluoride Filter: Crystal Quest
Fluoride reduction: Up to 95%
Activated alumina filters are among the most widely used applications to remove fluoride and arsenic, high TDS levels, and sulfate concentrations from tap water. Berkey filters are one of the most famous filters that utilize the underrated technology.
Activated alumina is made using aluminum oxide and it has a significantly high surface-area-to-weight ratio which helps trap contaminants for an extended period of time.
No, most activated carbon filters can’t remove fluoride. But that’s not necessarily a bad thing. A carbon filter is the most widely used water filter that can remove a litany of common tap water contaminants, first and foremost chlorine and chemicals.
Fridge filters – one of the most popular choices for filtering water at home – can’t remove fluoride. At least, we haven’t come across any refrigerator water filter that utilizes AA or bone char cartridges.
Carbon-based filter cartridges in refrigerator filters are effective at removing aesthetic contaminants like free chlorine.
Hence, if you are worried about going fluoride-free, now may be an excellent time to upgrade your filtration system. If you are looking for the same level of convenience, you should opt for a water filter pitcher instead, like the Clearly Filtered.
Fluoride in drinking water is a controversial topic, and people on both ends of the debate feel very strong about it. There’s significant debate about whether the oral-hygiene related advantages of fluoride outweigh the potential health risks involved.
If you are here, it’s safe to assume that you’d rather drink non-fluoridated water. Honestly speaking, not all fluoride is harmful. But, like all things in life, moderation is key.
Here’s a roundup of pros and cons related to fluoride in drinking water.
Here are a few tips to reduce your overall daily fluoride exposure:
