Best Fluoride Water Filter

Fluoride Water Filter

You might have a water filter, whole house or portable, that doesn’t filter out fluoride. That’s an issue for some, so the next time you’re shopping for a new system, make sure it has what you need. Finding the best fluoride water filter involves determining if you want a reverse osmosis system, a whole-house system, one that fits under your sink, one that sits on your counter, or a water pitcher. Ideally, fluoride water filters help make your drinking water taste better while removing harmful contaminants.

In this roundup, we’re looking at which filtration system is best for your need to remove fluoride and produce the best tasting drinking water. If you want a whole-house filtration system, we recommend the Aquasana Rhino Whole House Filter because of its capacity and UV filtration. However, if you’re looking for something that won’t compromise your water pressure, choosing a gravity-fed pitcher or countertop system might be optimal.

Fluoride Water Filter Buyers Guide

What’s The Deal With Fluoride?

Scientists conclude that fluoride is the 13th most abundant element (at 0.054%), narrowly beating out carbon (at 0.02%). Scientists have also discovered that there are higher concentrations of fluoride in seawater compared to freshwater. We can find this food grade element in several minerals, as well as our food, soil, and water. 

Some believe that we need to have fluoride added to drinking water to help prevent tooth decay. However, fluoride can have many adverse effects on your health that lead many to wonder if we really need to add it to water. Before looking at how fluoride could affect your health, let’s discuss how it gets into the water in the first place. 

We can find fluoride in water as a natural element that many think we need for the prevention of tooth decay. Many public drinking water facilities add fluoride in amounts as small as 1PPM. There are others who oppose adding fluoride to water because they believe it could provide a means for mass medicating. Some also believe that, if you consume fluoride, it could cause fluorosis. When dental fluorosis occurs, that means there’s a slight discoloration in your teeth’s appearance. This issue typically results in faint white marks on your tooth enamel’s surface. Even if your community doesn’t add fluoride to its drinking water, fluorosis can still occur. If a child receives too much fluoride over an extended timeframe, then they could get fluorosis. 

If you believe that you don’t need fluoride in your water, you can use a reverse osmosis filtration system. These filters remove fluoride up to 99%. You can also use a pitcher or countertop system that doesn’t feature reverse osmosis to effectively remove fluoride. Using a system such as those are optimal when you need to maintain water pressure in your household.

Types of Water Filters That Remove Fluoride

There are many different types of filters that remove fluoride in today’s marketplace. It doesn’t matter if you’re looking for a 5 stage whole house filter that removes fluoride or a stainless steel system type that sits on your countertop. While 5 stage water filters might use reverse osmosis to get the fluoride out of your water, there are many other filters that work just as effectively.

For example, countertop filters produce pure water with an optimal flow rate during fluoride removal. RO systems do a great job when you need to get rid of fluoride. An RO system might include sink filtration for great tasting water supply. Ideally, you’re looking for something that’s easy to install when providing a way to get quality water. 

Here’s a breakdown of the types of fluoride filters you can find today:

  • Under the kitchen sink filter for fluoride
  • Whole house water filters
  • Counter water distiller
  • Gravity filters 
  • Faucet attachments
  • Pitcher filter
  • Reverse osmosis water filter

What to Look for When Buying a Fluoride Water Filter

When you’re looking for filters, make sure you read through many fluoride water filter reviews. In doing so, you’ll learn more about replacement filters, contaminant reduction, if they’re easy to use, the water quality they produce, if they filter out healthy minerals, and if the filters are long lasting. When filters remove fluoride from water, that could mean they’re an RO filter featuring a reverse osmosis membrane. You might be looking for the best under sink filters that last a long time while meeting the standards.

Here’s a breakdown of what to look for when buying a fluoride water filter:

The system’s filtering process

Before you drink water, it goes through a complex filtering process. Make sure there’s a pre-filter to remove sediment and prevent bacteria or parasites from entering any filters. Then, make sure there’s charcoal or activated carbon to improve the taste, odor, and color of your drinking water. 

Some filters direct water through silica sand and, if this is the case, make sure it meets NSF standards. Then, make sure the filtering process includes the elimination of harmful chemicals and other contaminants that might be in your water. You may also find that some water filters add healthy minerals back into your water supply.

Ease of use

If using the water filter isn’t simple, then it might not be worth your money. First, you’re going to find it frustrating to use it and, second, it might not produce the highest quality water. For example, a gravity-fed system is easy to use because you’re filling a top reservoir with water and it pulls through the filters. That means gravity is powering the filtering process.

Some prefer the water capacity in a countertop style compared to the capacity in a pitcher. However, others like that they can put the pitcher in the refrigerator and have cold water each time it’s refilled. If you choose these types of filters, make sure you’re changing the filters frequently.

Your home’s filtering needs

If you’re living in an apartment or dorm room, your filtering needs are going to be significantly different than those who have families and are living in a house. For example, if you’re single and living in a small home, you might find that systems that filter 150 gallons are optimal. For water supplies that are in busy homes and use a lot more water, though, you might need to find capacities that handle a lot more.

You’ll also find that different filter types work best for an individual’s or family’s different water needs. For example, you’re going to use each type of filter most effectively if you understand their specific benefits. That means you must analyze your home’s water to understand which types of filters are going to work the best.

How Does Reverse Osmosis (RO) Work?

You might see products touting that they have reverse osmosis technology (RO). For example, the Aquagear water filter pitcher, iSpring, and APEC filters use reverse osmosis to produce fluoride free water. Companies like APEC remove fluoride chlorine and other harmful contaminants using activated alumina. Not only are these systems 100 BPA free, but the filter works by going through five stages.

That leads us to how RO works. These systems feature a series of carbon block filters, as well as a reverse osmosis membrane. You connect these systems to the cold water line in your house. Then, it uses your home’s water pressure to push water through the filters. In doing so, contaminants collect in a brine that flows down into your drain.

Reverse osmosis systems are installed into the cabinet space available underneath your kitchen sink. In a small storage tank is where the initial water storage is until you turn on the filter’s dedicated faucet. You can mount that faucet on your kitchen sink. The majority of RO systems feature between four and six stages.


For some, it’s difficult to find the best filters for fluoride. The main reason is that there are many options, including whole-house units, under the sink systems, pitchers, and countertop units. Our overall winner in this roundup is the Clearly Filtered Under Sink Unit because, even though it has a high capacity, it still features an affordable price. 

We also determined that there are two runner-ups, including the Pelican Whole House unit because it’s easy to maintain and the Aquasana OPTIMH20 system because it’s affordable. This under sink system available by Clearly Filtered fulfills a consumer’s need for filtering out fluoride in their drinking water supply.
