Is There a Water Filter That Removes Sodium?
No matter where you live, your water likely contains some amount of sodium. How much depends on the conditions of the local soil. The problem is that when there is a higher sodium content, the water becomes more corrosive. Fortunately there are solutions to control how much sodium is in your water.
What Is Sodium?
Sodium is a naturally occurring chemical element. It uses the symbol Na, and it is a soft, silver-white metal that is very reactive. In fact, it makes up approximately 2.6% of the earth’s crust, and it is the sixth most abundant element.
How Does Sodium Get Into Drinking Water?
Both sodium and chloride are elements that exist by nature in groundwater, which is the source of well water. The two combine to make table salt. Salt comes from the weathering of rocks and clay.
When it rains, the water erodes the rock, and sodium is released into water, including groundwater, which goes into lakes and streams. Most of the water supply comes from these sources. Often, salts containing sodium are dissolved into this drinking water.
In addition, salt can get into water because it is used as a water softener in wells. Sodium releases ions in water, and this process helps to reduce the iron found in well water.
Are Sodium and Salt the Same Thing?
Sodium and salt are not the same thing. In fact, salt is a combination of sodium and chloride. So salt is approximately 40 percent sodium. Often people use the words interchangeably, but they are different.
What Effect Does Sodium Have on Drinking Water?
One effect that sodium has on drinking water is that it can affect the taste. If the sodium level is between 30 mg per liter and 60 mg per liter, it does affect the taste. In addition, higher sodium levels in water make it more corrosive.
Finally, because taking in large amounts of sodium can be dangerous for people who suffer from high blood pressure or hypertension, high levels of sodium in water can be a bad thing.
How Can Sodium Be Removed From Drinking Water?
Fortunately, there are ways to reduce the level of sodium in drinking water to the recommended amount of 20 mg per liter. One option is to use a reverse osmosis water system. It actually reduces the amount of sodium by 94 to 98 percent by forcing water out of a permeable membrane, this membrane blocks the sodium.
Another method of removing sodium is through distillation, and sodium can also be removed with a deionizer. You can install a water treatment mechanism to faucets in your home to reduce sodium as well. There are several options available.
Water filters use these methods to remove sodium from the drinking water in your home. There are actually a number of different types of water filters that you can use in your home to manage the sodium levels in the water.
Reverse Osmosis Water Filter
Reverse osmosis is a technology that can remove any contaminants that are in molecule form. This includes sodium. It uses a permeable membrane to squeeze the water through and hold the contaminants behind.
This type of filter system helps to reduce sodium as well as many other elements, including iron, lead, calcium, and manganese. Once the water is filtered through the reverse osmosis system, it is healthy for drinking, clean, and free of molecular compounds.
In addition, this type of filter system has been known to make the water taste better. The reason for this is that elements such as sulfur, lead, nitrates, and others alter the taste of water, and they are removed. This is a filter system that is capable of removing sodium and improving the quality of your water.
Dual Stage Filters
These filters use ion exchange and filtration to remove sodium as well as chlorine and other heavy metals from water, but they do leave behind trace minerals such as potassium that are good for the human body. The way this system works is that water runs through two carbon filters into a tube that is connected to a faucet.
This filter is fairly simple to use and maintain, and it can be installed under the sink or on a counter. It is affordable, and it can be used for any faucet that you use for drinking water in your home.
With this type of water filter, all of the minerals, good and bad, are filtered out. It works by boiling the water into steam. Then, a fan blows the steam into a cooling chamber. This process literally removes everything, including heavy metals, contaminants, pesticides, sodium, and all minerals.
It does use electricity, and it takes time to process. You can get a range of sizes and styles, and it can be installed under a sink or in a container elsewhere. It really depends on how much water you need to filter.
Sodium Can Be Removed with a Filter
To answer the question, “Is there a water filter that removes sodium,” the bottom line is yes, sodium can be removed from drinking water with a filter. Which type of filter is the right one will depend on your water set up and what you want.
If you are using well water, you can get a reverse osmosis system to filter all of the water for your home. Although the initial cost may be high, it will pay for itself over time in terms of quality of water.
If you use city water, you may only need a filter that can be installed under your kitchen sink. You can choose between a small reverse osmosis system, and dual tap system, or distillation.
Although it is a good idea to make sure that your drinking water contains 20 mg per liter or less of sodium, you don’t necessarily need to remove all of the sodium. Some sodium is beneficial as the human body depends on it to perform certain functions. Evaluate what your needs are, and you can select the filter that is best for you.
