Best Fluoride Water Filter

Most states have rigorous standards of piped water that suppliers must adhere to. It is still common to find contaminants that may emanate from the treatment plant or in the supply lines. Moreover, municipal suppliers will add some chemicals deliberately to improve taste and balance the pH. 

Unfortunately, not everyone can enjoy drinking water polluted by these excess chemicals and other pipe buildups. Besides interfering with your drinking water habits, untreated water could lead to poisoning in the worst cases, such as excess heavy metals pollution.

Fortunately, there is a way of avoiding all these woes. We reviewed seven fluoride water filters to help you understand how they work and find out the options you have for your home. Our extensive reviewing and testing found Waterdrop WD-G3-W Reverse Osmosis Water Filter System to be the best product overall.

Why You Need the Best Fluoride Water Filter

A high-quality fluoride water filter enhances better-tasting water to improve drinking habits. More water in the body enhances the chemical processes of cells by creating a balanced pH environment. 

Some water filters have the capabilities of raising the water’s pH too. Most importantly, a water filter removes toxins and sediments found in water supplies that you would hardly know even to exist. These toxins may include heavy metals, excess chlorine and fluoride, and organic contaminants.

What to Consider Before Buying a Fluoride Water Heater

What should you consider before checking out the specifications of your to-be fluoride water filter? Some buying considerations that will point you in the right brand or model include:


Price is the first thing that you would want to consider if the idea of buying a water filter rings in your mind. Price is relative and will vary from one supplier to another, depending on several factors. 

For instance, the higher the quality of a product, the more you’re likely to part with. Similarly, a low-quality product will attract a lower price. Watch out for suppliers and manufacturers who offer free shipping and delivery. That way, you’ll enjoy a total subsidized cost, and the discounts can even be greater if you use online coupon codes and referral links.


Any machine product that you intend to use for long-term purposes should come with a warranty, water filters not being an exception. Clear warranty information shields you from unnecessary losses caused by quality issues emanating from the production or supply line. 

Kindly ensure that you understand the warranty terms of a product before paying for it. Some warranty conditions may only be enforceable on specific components, while others cover you for the whole product’s longevity.

Filtration Targets

Every water filter system has unique capabilities to deal with specific contaminants. Contaminants in drinking water may either emanate from the source or in the plumbing lines. If you’re dealing with municipal piped water, you would want a fluoride water filter that removes radioactive elements such as radium and uranium, excess chemicals such as chlorine, and heavy metals such as lead and copper, and arsenic.

Public walls may also contain fluoride added by local authorities to enhance the taste of natural water. However, you’ll deal with different contaminants in well water. Watch out for systems that can filter and remove organic contaminants, pathogenic bacteria, viruses, and silt sediments.

Factors to Consider When Buying a Fluoride Water Heater

It may still be challenging to choose the right fluoride water heater, even with the premium products recommended above. There is a surge in the number of fluoride water filters, including a generic option that mimics the original in nearly all ways. Consider the following factors before buying the best fluoride water heater to enhance your experience:

Type of Filtration

Besides brand, you might also want to consider the type of filter to determine whether you’ll have a good experience or depending on the type of water you’re dealing with. We can quickly tell that products with reverse osmosis (RO) filtration technology tend to have the best water filters. 

This filtration technology eliminates sediments and prevalent contaminants like pipe buildups found in ordinary tap water. Reverse technology water filters will be the best bet if you’re dealing with piped municipal water. OR fluoride water filters can also remove small amounts of organic contaminants such as herbicides and pesticides.

Some filtration techniques will require gravity force to function, while others need electricity. In case you opt for the latter, choose a model that features innovative technology to enhance energy efficiency. Some intelligent features that will save you energy include a dedicated “vacation mode” setting and auto shut-off capabilities when idle.

Consumption or Filter Capacity

The consumption or capacity of a product is similar to its lifespan. The higher the capacity, the more likely you’ll last with the filter to see its investment value. Even so, your capacity needs largely depend on the household’s size. 

For instance, a small home of about one to two members will do well with a countertop fluoride water filter of up to 500 gallons or lower. Similarly, an extensive home of up to eight or ten family members will require a whole house water filter of about 1,000,000 gallons and above. 

In that case, such a filter would last for up to a year, surpassing the 250,000-gallon mark, which is the average consumption rate of a big household per year.

Filter Longevity

Most components of a fluoride water filter have longer lifespans of up to five years, except the filter medium. Go for products that feature filtration media with extraordinary longevity of up to a year since standard ones only last for about six months. 

Even so, some manufacturers may still give false information about a component’s longevity and advise you to consider replacement once you notice decreased efficiency. In that case, you would want to watch out for decreases flow rate or excess fluoride taste to know whether you’ll need a replacement.

You could also go for products that come with extra purification elements like the Berkey brand. Each extra purification element comes with a longevity of about six months to reduce your trips to the store. That means you can stay up to two years without buying another set of filter media, depending on how much the manufacturer gives with every new purchase.

Micron Rating

Micron rating is the distance between particle contaminants and the filtration media. The higher the micron rating, the more big particles will pass the filter media. Similarly, the lower the micron rating, the safer your drinking water will likely be. What is the right micron rating for a whole house water filter? 

The choice is purely aesthetic and depends on your needs and the type of contaminants you’re dealing with. Inorganic minerals and heavy earth metals like copper and mercury will require a micron rating of about one and below. 

You can use a filter system with a higher micron rating of up to five if you only want to improve the taste of drinking water by removing odor, excess fluoride, and chlorine.

However, kindly note that nearly all filter rates in micron may not be ideal for removing viruses and pathogenic bacteria, except a few. In that case, you would want a water filter powered with UV capabilities to kill pathogens and bacteria.


A water filter’s certification is as important as the product’s quality. A certified product means that it is safe for human use and can filter your water up to a certain degree by tackling particular contaminants. The most prevalent certification for home-uses water filters includes NSF-listing. A product listed NSF standard 58 shows a certificate to remove all sorts of Total Dissolved Solids such as copper, arsenic, and lead, while NSF standard 43 offers certifications for aesthetics reduction. This may include eliminating odor, fluoride, and chlorine concentrations. Other NSF listing to watch out for include:

NSF Standard 44– Piped water often comes with excess minerals that could end up endangering your life instead of improving the skin tone. This level of certification guarantees the removal of excess mineral contaminants such as radium 226/228 and barium.

NSF Standard 53– This certification is common in nearly all the products featured in our review list. It guarantees and shows the effectiveness of health-related contaminants filtration. These contaminants may include lead or cyst.

NSF-Standard 55– You would want to buy a product listed with this certification if you’re dealing with excess industrial and organic pollution. This certification guarantees the removal of pathogenic bacteria, viruses, and microorganisms from your drinking water.


Lastly, you would want to consider the size of a water filter, especially if you’re maximizing space in your kitchen. Compact-sized water filters such as some of the models featuring above are easy to install and replace. 

They also have multiple applications as you can quickly carry them to the office or camping site, especially if you opt for countertop models. However, smaller water filters may not be ideal if you’re dealing with a big household. Most of them are tankless and will have a general flow rate compared to sizable models. 

Nevertheless, size is a purely aesthetic choice and varies from one homeowner to another.

Wrapping It Up

Access to clean drinking water is the best thing that could ever happen to your household. We live in a world full of uncertainties, deadly viruses, and all types of earth pollution. Thus, it will help if you take charge of your drinking water to guarantee its cleanliness and purity. Any of the water filters reviewed above will serve you well, provided you follow the correct installation process and replace the filter medium once it exhausts its lifespan. 

While all these products are of high quality, each has varying capabilities and unique features. Whatever works well in another home may not meet your household needs. Thus, consider all the factors discussed in the guide to determine which product meets your needs and expectations. You can buy these products from Amazon or official manufacturer websites.
