You might have been hearing about fluoride lately and although it might sound like some distant cousin of Flo Rida, this isn’t some new rapper on the scene!
In fact, it’s a chemical that has been linked to an increased risk of cancer (1).
And even brain damage (2).
And it’s being added to our water supplies all across the country.
Fluoride is added to our water because it promotes healthy teeth - but more people than ever are worried about dangerous side effects, especially in children’s health. Since fluoride is already found in toothpaste, it’s easy to exceed the safe dosage if you’re drinking fluoridated drinking water as well.
Fortunately, there’s a range of fluoride water filters on the market. Powerful under sink filters can give you fluoride-free water straight from the faucet, and affordable water pitcher filters can give you purified water kept in the fridge.
Read on to discover how to ditch the fluoride - and flourish!
The Best Fluoride Water Filters of 2021
Fluoride is a ubiquitous scourge in our water supply - a high price for clean teeth when you consider the impact it can have on our health. Here are the top rated fluoride water filters of 2021 on the market.
APEC’s under-sink water filter is a fantastic product if you’re looking to install a water filter in your kitchen and then feel the freedom to forget all about it. It has been built with premium materials, ensuring a long life as well as high performance.
Because this model goes under the sink, you don’t really need to worry about how it looks. The tank and filters are housed in BPA-free plastic and your water travels through food grade tubing, ensuring there are no concerns about added contaminants. The faucet is guaranteed leak-free, so once it’s installed you’ll have fresh water flowing where you want it.
Because it’s an under-sink model, it requires some serious installation. You’ll need space beneath your sink, a range of tools to plumb the device into your mains water supply and you’ll have to drill a hole for the faucet in your countertop. It might be best to call in the professionals!
The upshot of this installation drama is long-term water filtering. The five-stage filter system included by APEC is designed to remove a wide range of contaminants - not just fluoride - from your water. With a filter lifespan of 12 months, an annual service will keep your water in tip-top shape.
A powerful under-sink system with a premium price tag and be ready to break a sweat with installation.
From a solid plastic chassis to food-grade piping, iSpring has gone to lengths to ensure that this water filter system is built to last. The faucet is built from stylish stainless steel with an attractive spout and will look right at home in any modern kitchen.
As with any under-sink water filtering system, installation will take time out of your day. But iSpring has included detailed instructions and a DIY guide - so if you’re tooled up, this should be something you can do at home. Maybe have a handyman’s number well… handy, though.
As for filtering, with six independent filtering stages, this is a system you can trust. As well as reverse osmosis, which removes fluoride, this filter can handle just about anything your water supply throws at it. And iSpring has also included a remineralization filter that restores the natural balance of your water, making it healthy and delicious.
iSpring’s reverse osmosis filter is also exceptionally long-lasting - up to three years. That makes it one of the most reliable filters on the market. Of course, the other filters need replacing around every 12 months but if fluoride’s on your mind, you’re covered for years.
A mid-range price tag belies a premium product. This system does it all, from long lifespan fluoride removal to remineralization to keep you and your family healthy.
This top-tier system isn’t for water-drinkers on a budget. With a price tag that will make your eyes water, you’d expect a premium system.
Fortunately, Home Master has spared no expense in the construction of this fluoride filtering system. All materials have been built according to NSF certification guidelines - that means there’s nothing nefarious leaking into your water supply.
However, when it comes to design, this unit may leave something to be desired. The faucet isn’t as stylish as other units and may seem more suited to commercial kitchens than urbane homes. With a flow rate to boast of, however, it certainly has the water flowing.
The modular design of the unit - meaning several detachable systems are connected together - makes installation, and filter replacement, a breeze. You’ll need a few tools, but DIY tutorials are included with the product.
Home Master’s water filter relies on reverse osmosis for its fluoride filtering, but it contains several other filters, including mesh and carbon, to create a completely pure water experience. And a final remineralization stage restores calcium and magnesium to your water supply, ensuring a drinking experience that’s as nourishing as it is pure.
Filters should last a year or 2000 gallons. On top of an already significant price tag, this adds a long-term running cost that shoppers should be aware of.
Powerful remineralization means that this gives you great-tasting and nourishing drinking water - but it comes at a price.
Countertop systems are valued for their ease of use as well as their portability. Unlike an under-sink model, you aren’t trapped in the kitchen. That makes them great for traveling, barbecues and business meetings.
Berkey’s Big countertop water filter system might not be coming on a camping trip, with its 2.25-gallon capacity, but if you have countertop space, this is a great option for getting fluoride-free water for your family.
The shiny stainless steel chamber is an eye-catching addition to your kitchen, with a stylish embossed Berkey logo in pride of place. The unit is built from BPA-free plastics and food-grade rubber plugging that ensures there’s no water leaking on your counter.
One of the main benefits of a countertop system is the ease of installation - it doesn’t need to be plumbed in, nor receive mains power. Water is simply added to the top chamber and filtered as gravity draws it down.
The unit itself contains two sets of filters, one for general purification and another targeting fluoride. The PF-2 filters are not quite as effective as reverse osmosis filtering for removing fluoride - but up to 95% of fluoride can be removed.
This unit doesn’t come cheap, however, and although Berkey’s purification filters have a 3000-gallon lifespan, it’s important to note that the fluoride add-ons can purge fluoride from just 1000 gallons. This could become costly to keep your family fluoride-free.
For countertop fluoride filtering, this is an effective unit - just remember to factor in running costs.
Megahome’s countertop water distiller consists of a boil chamber that converts water to steam. The steam travels through coils at the top of the unit, whilst all contaminants are left in the boil chamber and your water recondenses in a secondary jug, simple H2O.
It’s an attractive unit with a stainless steel boil chamber and a transparent glass jug so you can see your crystal clear water. They’ve also opted for high-quality components on the inside, ensuring that your water is never in contact with plastic.
The distilled water jug features a porcelain spout - a nice touch that prevents any liquid leaks or spills when you’re pouring your pure water.
The gallon capacity isn’t the biggest on the market and if you’ve got mouths to feed you’ll quickly run out. The downside of distillation is that it takes time to bring your water to the boil - and then cool again. This unit distills a cool gallon in 5.5 hours - so plan ahead.
They’ve also included optional filters which trap any contaminants that vaporize, such as chlorine - but distillation alone is effective at removing chlorine. And since the distillation process is what filters your water, you don’t need to replace filters - ever.
No need to worry about replacement filters with this well-built distiller, just plan ahead to give your water time to boil.
Unlike most under-sink systems, there’s no tank involved in this unit - simply a filter that is installed below a faucet. For those of you with compact kitchens, this is a great design.
The filter is only compatible with Frizzlife’s faucet, but you buy the two together as a bundle. There are two faucet designs to choose from - a classic stainless steel as well as a stylish matte black, so there’s something to suit every kitchen from traditional to contemporary design.
Although the faucet is rated to 1.5 gallons per minute (GPM) capacity, the filter actually restricts water flow to around 1.08GPM. Most under-sink units have a tank for precisely this reason - filters slow down your water flow, but with this unit you’ll have a slightly restricted flow rate.
Nevertheless, it’s a streamlined design and exceptionally easy to install. The standard kit is compatible with countertops up to 1.5” in depth, but if you have a working surface that’s thicker than this there’s an additional extended stem for the faucet - so Frizzlife really has thought of everyone.
The filter itself works in two stages and combines a technical mesh with a carbon filtering stage. As well as fluoride, lead and chlorine are removed almost completely from your water. Although it has fewer stages than many other filters on the market and may not remove esoteric pesticides and the like, this does preserve some vital minerals such as calcium and potassium in your water supply.
Filters are easy to replace with a twist-off system, although with a lifespan of up to two years, that’s not something you’ll be making a habit of anyway.
An affordable and compact system that’s a great choice for small kitchens.
Aquagear’s well-built water filter pitcher comes with a lifetime guarantee, and if it ever breaks, Aquagear will replace it no questions asked. Not that it should, though - this is a sturdy pitcher built from tough BPA-free transparent plastic.
It has an ergonomic handle that makes it comfortable and easy to pick up and with a half-gallon capacity it never becomes unwieldy. The spout has a hinged cover, making it easy to pour, but preventing spills - this is a great touch as leaky spouts can quickly ruin any dinner party!
It’s also exceptionally easy to set up an Aquagear water filter pitcher - simply clip the filter in, and fill. Water trickles down from the upper reservoir to the lower chamber, filtered as it goes. However, you’ll have to plan ahead - it takes time for the water to travel through the filter, and with just half a gallon in capacity, you don’t get a lot of water for your wait.
The filters themselves promise impressive filtering - but fluoride comes as an afterthought. These filters are geared towards giving you great tasting water with a reduction in chlorine and whilst the majority of fluoride is removed from your water, up to 10% remains.
The filters are rated to a capacity of 120 gallons, so if you have a thirsty family you’ll find yourself refilling and restocking on a regular basis. The unit’s low price disguises this long-term cost, and it may not be quite as good a deal as it seems.
For simple set-up and great tasting water, this is a good buy, but it’s let down by a limited capacity and long-term filter costs.
When it comes to design, all you have to worry about with an under sink system is the faucet - everything is tidily tucked away in kitchen cabinets. And Aquasana has gone all out to offer a stylish faucet, with three finishes to choose from to match any kitchen design.
And everything below the sink is well constructed, from BPA-plastic tanks and filter housing to rubber components. And if you were left with any concerns, there’s a 2-year warranty on the product to set your mind at rest.
Although there’s a labor-intensive installation process, the instructions are clear and with the right tools it should be an accessible DIY job. There’s the satisfaction of fluoride-free drinking water, and the satisfaction of a job well done to look forward to.
The filter process relies on reverse osmosis, one of the most reputable fluoride filtering mechanisms on the market - this premium under sink system promises a 95% reduction in fluoride, as well as up to 99% reduction of a further 80+ contaminants.
The reverse osmosis filters have a lifespan of one year - but the carbon filters need to be changed every six months, adding a long-term maintenance cost to an already substantial price tag.
An impressive under sink system with top-tier filtering and a healthy warranty for added security.
Picking up this water pitcher from its shapely handle, you immediately notice that it’s sturdy and well built, with no creaks coming from its plastic body. The filter pitcher consists of an upper reservoir with a filter placed at the bottom, and a lower chamber where the purified water collects.
The pitcher itself is of standard design, but reassuringly built from BPA-free plastic, so you know nothing is additionally contaminating your newly purified water. The handle is solid, but not designed with finger imprints, making it slightly awkward to lift.
The lower chamber has a 2/3rd gallon capacity making it slightly larger than other filter pitchers, but not oversized so you can’t store it in your fridge for crisp, cool and pure water.
What makes a Clearly Filtered water filter pitcher stand out is the filters designed and built into the pitcher - hundreds of contaminants are eliminated, including herbicides, pesticides and viruses. Of course, it works on fluoride too - eliminating up to 98% of this substance.
With a hundred-gallon lifespan for each filter, you’ll be replacing these on a semi-regular basis. Fortunately, as well as an affordable price tag attached to the pitcher itself, replacement filters won’t break the bank.
Impressive filtering from this water filter pitcher.
Home Master has designed a water filter that fits onto your faucets, creating an easy installation method for tap water purification. However, this creates something of an eyesore on your countertop as, unlike under-sink models, the filter takes pride of place by the faucet.
The filter and tall plastic filter housing sit by the sink, distracting from any minimalistic kitchen design. However, if aesthetics come second fiddle then you’ll have no issue with this design.
A rubber grip pad - included, of course - secures the filter to your countertop, whilst a screw-on faucet attachment connects the system to your sink without any complex plumbing. Make sure your faucets have a removable aerator cap, however, otherwise this product won’t be compatible.
It takes seconds to install, and that’s what makes this product so appealing - you can take it anywhere and have pure water pumping in hotel rooms around the world.
When it comes to filtering, it does a solid job without breaking boundaries - around 93% of fluoride is removed from your water supply, along with chlorine and other chemicals. There are better filters on the market, but nothing quite so portable - if you’re hitting the road, you may have to compromise.
With a 500-gallon filtering capacity, each filter is long-lasting, meaning you’ll never be caught short on a trip. Combined with an affordable unit price, this is a great option for those on a budget as well as frequent flyers.
This stands out for its portability and filter capacity, making it an affordable product that will appeal to travelers and shoppers on a budget alike.
The Fluoride Water Filter Buying Guide
Looking out for yourself and your family is hard enough in today’s world without worrying about what’s in your water supply, but sadly you can’t always trust what comes out of the taps.
From lead, leaking out of old pipes, to pesticides and herbicides from farm runoff, there are plenty of nefarious chemicals in our drinking water.
But what about fluoride? Whilst fluoride occurs naturally in low doses, it’s actually added to many water supplies around the country, and associated with healthy teeth.
So is it safe? Let’s take a quick look at why you might be worried about fluoride in your drinking water.
Why Should You Be Worried About Fluoride In Your Water
Fluoride was first added to water supplies in Michigan in the aftermath of World War II and local studies quickly showed an improvement in the dental health of local citizens (3). It quickly caught on until it was being added to our drinking water, all across the country.
Sure, healthy teeth are important. But fluoride is also a chemical with a few unpleasant side effects, and many people are increasingly concerned that it isn’t worth the risk for a few less cavities.
For example, studies have shown that fluoride has been associated with a form of bone cancer called osteosarcoma (4).
Connections have also been drawn between brain function and fluoride, as fluoride has been seen to encourage calcification of the pineal gland (5).
Whilst the jury’s still out about the risks of fluoride, many people don’t want to take the risk for themselves and their families. Or they just don’t like the choice being taken out of their hands.
If you’re one of these people, a fluoride water filter is a household essential. But which one is right for your kitchen? Read on to discover everything you need to know about fluoride water filters.
A Fluoride Filter Deep Dive
Every fluoride water filter system is different. From reverse osmosis filters to gravity-fed pitchers, it's important to know your filter system inside out. Here are the three main ways a water filter system is defluoridating your water.
Reverse osmosis is the gold standard in fluoride water filters, and the majority of multi-stage, under sink systems incorporate a reverse osmosis level to strip fluoride from your water supply.
Reverse osmosis removes around 95-99% of fluoride from your drinking water, making it highly reliable. These filters also have a longer lifespan, tolerating around a year of heavy use without becoming compromised.
Probably the second most common mechanism for filtering fluoride from home water supplies is activated alumina. They work by a process of adsorption, whereby fluoride molecules stick to the alumina as water passes through.
Activated alumina works effectively at first, but often performance is compromised over time. For this reason, activated alumina filters have a shorter lifespan than those utilizing reverse osmosis, and are often slower acting.
When a filter system uses affinity media, it implies that there are certain chemicals contained within the filter that have been chosen to specifically target certain compounds and neutralize them.
Many water filter pitchers, which rely on activated carbon for their primary filtering, will include such affinity media to reduce fluoride content in purified water.
However, brands often leave it ambiguous about what’s actually doing the work here - and as such it’s difficult to know exactly how much fluoride will be removed through your water filter.
Now that you understand the types of filters a little better, we can start exploring the way these systems can differ. There’s a fluoride water filter system for every kitchen, from spacious under-sink models to filters you can practically pocket and take on holiday!
Under Sink System
The daddy of the water filter system is the under-sink system. Like the name suggests, the bulk of this water filter system slots in under your sink - so as well as offering powerful filtration and pure water on tap, it also has the least impact on your kitchen aesthetic.
Under-sink systems consist of a water tank, filters and a faucet and are plumbed in. Water is drawn from your pipes and through the filters into a chamber below your sink, and when you turn on the faucet you have instant, purified water gushing.
Because of all this hardware, they entail a considerable time investment for installation - you’ll need a free afternoon and a variety of tools. However, they tend to boast accessible DIY instructions, so you won’t need to call in the experts.
Countertop systems can’t offer purified water straight from the faucet, but they can fulfill your purification needs. They are usually gravity fed, and work by drawing water from an upper chamber and through a filter stage, leaving you purified water in a lower tank, fed out through a spigot.
These hefty systems can hold several gallons of water at once, so if you’ve got a thirsty family they’re a great choice. The downside of the countertop system is that it’s too big to fit in any domestic refrigerators, so your water stays at room temperature.
Water Filter Pitchers
Water filter pitchers are like their countertop cousins - water is drawn down, through a filter, from an upper chamber into a lower pitcher. However, they’re built much smaller - typically with a capacity of around ½ to 2/3rds of a gallon.
These bijou units fit snugly into the fridge, giving you the added pleasure of a crisp, cool snap to the pure taste of your filtered water.
However, a half-gallon doesn’t go far on a hot day, and when you’re waiting up to several hours for water to be drawn through the filter for a refill you can get really thirsty.
Water distillation is a tried and tested method of purification, harking back to when the pilgrims would boil their water to purify it. Of course, the technology has come a long way since then, and now entails the conversion of water to steam, before tubing separates the gaseous water from unpleasant contaminants. Water - and just water - is then collected in a second chamber.
Since this relies on bringing water to the boil and then waiting for it to cool, it’s a time-consuming process - something best switched on before bed, so you can enjoy a pure glass of water in the morning. It’s a foolproof method of purification, however, so for that crystal clear H2O it might be worth the wait.
What To Consider When You’re Buying A Fluoride Water Filter
With so many varieties of fluoride water filters, it can be hard to narrow them down. Here are the factors you should be considering when shopping for a fluoride water filter, to help you choose the best filter for your home.
1. Testing The Waters
From lead to chlorine and from pesticides to pH, there are so many things lurking in our water supply. Whilst you’re out to eradicate fluoride from your faucets, you can choose a water filter that targets other contaminants too - and protects your family from a wide range of risks.
Testing your tap water doesn’t only help you choose the most targeted filter for your needs, it also indicates the lifespan you can expect from your filters. If your water quality has a low baseline, you’ll be changing your filters more frequently.
2. Choosing Your Filter Type
Gravity-fed or reverse osmosis? These questions can be answered by looking at the needs of you and your family. If you’re glugging gallons of water every day, a water filter pitcher isn’t going to cut it - a speedier filter utilizing reverse osmosis might be the way to go. On the other hand, if it’s just you at home you can save time and money choosing a more compact option.
3. Filter Lifespan
Not all filters are created equal! The filter’s “lifespan” refers to the volume of water it can purify before its performance drops off, and it can vary dramatically. Filters with a short lifespan can lead to a long-term running cost for your system, so choose carefully.
4. The Installation Process
Accessing perfectly pure drinking water shouldn’t be hard - but with some fluoride water filters, you’re going to need to knuckle down with installation before you’re sipping a refreshing glass of water.
Under sink systems typically need to be attached to your pipes, and require a faucet to be installed in your countertop. Checking the compatibility of your pipes and work surface depth is a must - and some larger systems need professional installation.
Countertop systems and water distillers are quick and easy to set up - but in the long term, you’ll be carting them back and forth to the faucet to fill them up.
The installation process is often a trade-off - a little more effort now and you’ll have fluoride-free water gushing from the faucet.
5. Filter Maintenance
Hassle-free filtered water is a dream, but to get the best out of your fluoride water filter, and to ensure effective filtering, a little maintenance is essential. Ensure you understand how to replace filters, and whether they simply swap out or you’re going to have to reach for the tool kit.
Under sink systems with water chambers might also need regular scrubbing, whilst countertop pitchers just take an occasional rinse. Don’t want no scrub? Opt for a simple countertop system!
6. Checking The Warranty
In this world, nothing lasts forever and although we’d like to rely on our appliances, things do go wrong. The warranty attached to fluoride water filters varies greatly - from six months to lifetime guarantees.
Some brands also offer different warranties for the filters themselves and long-term warranties for the filter system. Don’t get bamboozled when you’re buying - opt for a longer warranty for peace of mind.
Water gives us life - you should be able to rehydrate at home without concerns about cancer and brain damage. That’s a high price to pay for cavity-free teeth.
Not every water filter system is designed to eliminate fluoride from our drinking water, so you need to read the fine print to be fluoride-free.
But every filter system in this article is fine-tuned to flush fluoride down the drain.
Whether you fancy a reverse osmosis under-sink system to give you fluoride-free water from the faucet, or you prefer a simple countertop fluoride water filter, there’s a system for every home.
Keeping your family safe is a challenge in modern society, but your home should be a sanctuary from the risks of the outside world. A fluoride-targeting water filter system gives you the peace of mind you deserve at home.
Don’t wait - go fluoride-free today!
