We all have heard about fluoride in daily life. In safe amounts, fluoride is used in toothpaste, mouthwashes, and food supplements. However, it is also found in water because it is a naturally occurring element found in soil, plants, rocks, and air (trace amounts). Fluoride in water, above the safe limits, can be harmful for you and especially children. This guide will discuss the safe level of fluoride in drinking water, its health effects, and how fluoride can get in drinking water. We will also explore how you can test the presence of fluoride in water and what’s the best way to get rid of it. We will list the best filters available online to remove fluoride and a buying guide to help you select the best fluoride water filter.
Let’s get started!
What is the safe level of fluoride in drinking water?
EPA lists the safe level of fluoride as 4.0 mg/L. It means that in 1 liter of water, a maximum of 4mg fluoride is safe for your health. Above this limit, fluoride can be harmful for you and your family’s health. For children, the maximum level of fluoride is defined as 2.0 mg/L. Above this limit, fluoride is potentially dangerous for your child’s oral health.
As we have already discussed the safe limits of fluoride in water, it is time that we look at the health effects of excessive fluoride in drinking water. Please keep in mind that all the effects listed below manifest them after prolonged exposure to fluoride. Exposure for a short time is usually harmless and may not cause any trouble.
Research has shown that fluoride can cause the following severe health problems
- Dental fluorosis
- Bone fractures
- Skeletal fractures
- Low IQ scores in children
- Kidney problems
- Thyroid problems
- Neurological issues
Dental problems are more common in children as compared to adults. The reason is that children’s teeth are developing until their teenage. Adults have fully developed tooth structures, and fluoride is not likely to impact them. Research shows that children under are most susceptible to fluoride. On the other hand, adults can suffer from bone fractures, bone pain, and tenderness, if exposed to high levels of fluoride for a long time.
How fluoride gets in the water
Fluoride gets in drinking water due to natural geological changes in the composition of soils and bedrocks. Some areas in the US have naturally occurring high levels of fluoride. Fluoride can enter the water as it moves through rocks and aquifers. Fluoride is also added to tap water as a measure to reduce the cavities and enhance the oral health of the particular area. It can also get into your system through water additives, which promote strong teeth, erosion of natural deposits, and discharge from aluminum and fertilizer factories. If you are living near such factories, there is a high chance that you are facing a high-fluoride problem in your water.
How to find out the presence of fluoride in your drinking water?
You can use the following tools to know about the presence of fluoride in your drinking water
CDC Tool – CDC has developed a tool that can tell you whether the water in your area has been fluoridated or not. The tool can be used to enter your state, select your county, and then look for the municipal system which supplies you water. The tool’s problem is that it only tells you whether fluoride has been added in your water or not. It doesn’t tell you about the amount of fluoride in your water, or is it safe to drink or not.
Consumer Confidence Report (CCR) – EPA issues annual reports on the quality of tap water in the country. It will help you evaluate the water quality in your area and what contaminants are present in your water. All the details regarding this report are available on EPA’s website.
Water Testing – The most common method majority of Americans use to know about fluoride is to get their water tested. You can get your water tested at home or hire the services of a professional lab. While home testing gives instant results and it is cheap, it is, however, not reliable. Lab testing, on the contrary, is a bit costly but gives reliable and true results. Make sure you look for a certified lab to get your water tested. Please keep in mind that fluoride is colorless and odorless, you cannot estimate its presence in the water. Therefore, the only way to know about its exact amount is a water test.
What’s the best way to get rid of excessive fluoride in water?
If we were to remove sediments, chlorine smell, and taste, heavy metals from water, we could do it by running down water for a few minutes. We can get rid of certain smells from water by using cold water. For fluoride, we cannot use any such remedies. We have to rely on water filters.

- Best for: bacteria, bad taste and odor, chlorine, sediments, and other harmful contaminants
More Features: This 6-Stage water filter system maintains the natural pH level of water by the remineralization process.
Filtration Capabilities:iSpring is one of the leading companies to manufacture reverse osmosis filtration systems. It is best for large families and offices. It comes with a 6 stage filtration set up to provide you with pure and healthy drinking water. The first filter is a sediment filter that removes sediment, dust, sand, and other suspended particles from your water. It has a rating of 5 microns. The sediment filter does two things; it ensures that your water does not have suspended particles. Secondly, it enhances the life and working of the next filters by keeping them safe from sediments. The 2nd filter is a granular activated carbon, and it removes chlorine taste and odors, and cloudiness from your water. Next up is the CTO filter, which works against the VOCs, chemicals, chloramines, insecticides, herbicides, pesticides, and other harmful dissolved pollutants.
The 4th stage is the RO membrane. It is the heart of the system and has a rating of 0.0001 microns. It is so small that it allows only water molecules to pass through. Everything else in the water, like fluoride (up to 99%), lead, iron, and heavy metals, total dissolved solids are removed at this stage. If you take a water sample after passing from iSpring’s RO membrane, it will be like commercially purified water. The 5th stage is the post-carbon filter, and it removes any residual odors and tastes from the water. The final stage is the pH filter stage. This stage increases water alkalinity slightly, adds back the healthy minerals lost during the RO stage, and makes the water fit for drinking. Overall the filter can remove over 1000 contaminants from the water. The RO membrane is capable of catching microorganisms as well.
Filtration Capacity and Filter Replacement: The filter can provide you with 75 gallons of water daily. It is enough for a large family, a big office, or a small restaurant. It comes with 3.2 gallons pressurized tank with a 2.5 gallons holding capacity.

If you are renting a property, you may not be able to install an under-sink system in your kitchen. If you can make such alterations, then well and good. Otherwise, you can do the needful with a water pitcher or a countertop water filter that does not need any drilling.
What are your water needs?
It all comes down to your water needs. If you are an individual or a couple, a pitcher may be enough to meet your daily water drinking needs. For families, we suggest you buy a more powerful countertop or under sink filtration system that has more capacity. For large families, the reverse osmosis system is the best.
Some other factors to look for
We have discussed the primary factors above; now look at some of the secondary factors. These factors are related to the working of the filter.
Ease of use
Your filter must be easy to use. If you are getting a pitcher, it should be easy to clean, open, refill, and close. Similarly, under the sink system or RO systems must be easy to operate. There is no need for you to adjust them daily.
Filtration Capacity and Filter Replacement
Look out for your required filtration capacity or daily water needs. Water pitchers have a shorter life as compared to other systems. Similarly, pitchers need more frequent filter cartridge replacement as compared to under sink systems. Filter replacement should also be easy. There is no need to spend hours on just replacing the cartridges.
Ease of Installation
Look for a filter that is easy to install. If you are buying an under the sink filter, make sure you have ample space for installation. RO filters are big and need a lot of space as compared to countertop or other under sink system. Another thing to keep in mind is to look out for space under your sink. We don’t want you to make alterations under your sink or return the filter. Such things create a lot of hassle.
Always keep your budget in your mind before buying the filter. Make sure that the replacement cartridges are also in your budget. You would need to replace filters every 4-6 months for most of the water filters.
Look for a filter that comes with certifications from WQA and NSF/ANSI. These organizations are leading bodies and ensure that the manufacturers are meeting working consistency and reliability standards.
Filters with warranty give you peace of mind for a certain period. When you know that you won’t have to pay for any issues in the next 1-5 years, you buy with confidence. It is an added benefit and increases the value of your money.

When do I need to replace the filter cartridge?
Most filters have a stated life. Some of them come with a light that signals you to change the light. The best way to assess that your filter’s life is over is to monitor the flow rate. If you notice a decrease in flow rate near the changing deadline, understand that it is the time to replace the filter.
Is boiling water effective against fluoride?
No, boiling your water will not remove fluoride from it. It can only be filtered from the water. Some people claim that distillation can remove fluoride from water, but we are skeptical about it. No trustworthy source has claimed that distillation can remove fluoride.
Can water softeners remove fluoride?
No, water softeners are meant to remove hardness in your water.
We have listed all the best fluoride filters available in the market at the moment. Buy with confidence from the list above and say goodbye to impure water. All the filters listed above are outstanding and perform excellently well. Once installed, you don’t need to worry about anything again.
