do refrigerator water filters remove fluoride

Water filters sift out many particles but do refrigerator water filters remove fluoride?

Fluoride is commonly found in water supplies. While fluoride can improve dental health, many worry about long-term use.

While there is no evidence that the minimal levels of fluoride in drinking water are harmful, some people prefer to avoid it.

Refrigerator water filters do not entirely remove fluoride. They typically only remove lead, chlorine, and volatile organic compounds.

That said, some refrigerator filters can reduce the amount of fluoride in your next glass of water. Carbon filters and reverse osmosis filters can extract some fluoride from the refrigerator water.

If you’re truly concerned about fluoride in your water, it’s best to purchase a home water filter that can remove it.

Refrigerators with water filters are convenient, but do refrigerator water filters remove fluoride? Appliances with carbon filters and reverse osmosis filters remove most fluoride.

Do Refrigerator Water Filters Remove Fluoride? Fluoride Sources

Fluoride is a mineral found in many products we use and consume daily, such as toothpaste, mouthwash, and even some bottled water.

It’s also added to many municipal water supplies to improve dental health.

The mineral also bonds with other elements to create new substances. For example, sodium fluoride is an inorganic compound found in drinking water, preservatives, and even rat poison

Another fluoride-based compound, sulfuryl fluoride, has even been widely used as an insecticidal gas.

While fluoride can prevent cavities and improve oral health, ingesting excessive amounts can cause health problems, including cancer.

That’s why it’s important not to swallow toothpaste or mouthwash that contains fluoride.

TIP: Avoid ingesting fluoride by researching and reading labels on your food and drinks.

Why Don’t Refrigerator Water Filters Remove Fluoride?

doesn't remove flouride

The answer is that most refrigerator water filters use activated carbon to remove impurities from your water.

Unfortunately, activated carbon doesn’t absorb fluoride completely. About half of it will pass right through the filter.

TIP: Activated carbon and activated charcoal are often used interchangeably, so don’t be fooled by claims that one or the other can remove all fluoride.

Reverse Osmosis Filters

Reverse osmosis (RO) filters are a type of water filter that forces water through a semipermeable membrane. This process removes most impurities from your water, including fluoride.

While RO filters are effective at removing most fluoride, they have several drawbacks.

Some refrigerators feature reverse osmosis filters, but they are not common. Additionally, RO filters are expensive and require frequent maintenance.

A good quality RO filter can cost hundreds of dollars up to a few thousand, making them impractical for many people.

Second, RO filters require a lot of water to operate. For every gallon of filtered water, you’ll get two to three gallons of wastewater produced.

This wastewater must be properly disposed of, which can be difficult and expensive.

Third, RO filters can remove beneficial minerals from your water, like calcium and magnesium. When this happens, the water can taste bad and cause health problems if you drink it over time.

TIP: Speak with your physician about any health concerns before investing in an RO system. They can shed light on how it might impact existing conditions.

This process removes impurities, like fluoride, from your water.

Ion-exchange filters are not as common as carbon filters, but they are becoming more popular. They are generally more expensive than carbon filters but require less maintenance.

TIP: If you’re handy, many home improvement stores have ion-exchange filters available.

Reverse Osmosis Filters

Reverse osmosis filters can remove fluoride from your water, as we mentioned earlier.

While RO filters are effective at removing most fluoride, they have several drawbacks that you should consider before purchasing one.

Ultraviolet Filters

Ultraviolet (UV) filters are a type of water filter that uses ultraviolet light to kill bacteria and other impurities in your water. UV filters effectively remove fluoride from your water.
