What Does a Refrigerator Water Filter Do?

If your refrigerator comes with a water tap, it can be connected to a water line and you can use it to drink chilled water all year round. In theory, this is a great way to have a constant source of cold drinking water. But what do you do when your tap water tastes bad?

Your fridge will receive the same tap water, and even though it will cool it down, it won’t change its bad taste. This is where a refrigerator water filter comes in handy. Check out the best water coolers and the best water jug coolers here.

Why Is a Refrigerator Filter Important?

Refrigerator Water Filter ReviewsWell, one of the reasons a refrigerator filter is important is that it makes your drinking water taste better. In fact, some of the best filters will make the water taste great, just like fresh stream water would. Another important reason to use a refrigerator filter is that it’s healthier. If the water is not filtered, it will get directly into the fridge’s water recipient. And while it stays there, the bacteria, viruses, and parasites in the water will start to multiply. So when you drink that water you will actually ingest a lot of contaminants.

And bacteria and viruses are not your only problem. If your water comes from a municipality water line, the bacterial contamination is pretty low, to begin with. But if your water comes from a municipal line, it means the water is treated. And most towns and cities use chlorine to treat the water and fight off bacteria.

Chlorine is a great disinfectant, and it will destroy most of the harmful bacteria, viruses, protozoa, and parasites in the water. But chlorinated water also has a downside. It’s not healthy. In fact, recent studies show that those who drink chlorinated water are up to 93% more likely to suffer from a form of cancer than those who don’t.

Even though chlorine was one of the first water treatment solutions and it was a great help in stopping the spread of waterborne diseases, it too might be harmful to us, especially if we consume a lot of it, which we unfortunately do. It seems that the average American consumes 300 – 600 times more chlorine than it’s deemed safe to ingest.

And the consumption of chlorine is not the only problem. Another problem is that chlorine mixes with the small amounts of organic compounds that float in the water. It produces some dangerous elements called Trihalomethanes. These elements are harmful to the human body where they stimulate the production of free radicals that ultimately lead to cell damage. Some studies discovered that trihalomethanes are highly carcinogenic. Even the small amounts we ingest from the water can be harmful to us.

Using a refrigerator filter will not only remove the remaining bacteria, protozoa, and parasites from the water, but it will also remove the chlorine, heavy metals, and some pharmaceuticals as well. This will make the water healthier to drink and better tasting.

Inline Water Filter Buying Guide

Best Refrigerator Water FilterAs you could see in our short reviews, even though they might look alike, refrigerator water filters remove different contaminants from the water and they have different longevities. This can make finding the right refrigerator filter difficult at times. In the following section, we explain how to find the right water filter for your fridge and how to install it properly.

How Does A Refrigerator Water Filter Work?

These filters are mounted on the back of the refrigerator in line with the water source. As the water passes through the filter, it has to pass through several filter mediums that will remove the contaminants in the water. Here’s how they do it:

Large Mechanical Filter

The first filter medium used by all refrigerator filters is a mechanical one. This filter medium will remove all the sediment, debris, rust, and other large contaminants that might be floating in the water. Depending on the filter model, this medium might be made out of fiber, or it can be made out of other porous materials, such as sand. When the water passes through this filter, some of the contaminants floating through it will be trapped in the medium so they won’t end up in your drinking water. Some mechanical filters can be so effective they will also remove part of the bacteria that affect the water.

Fine Mechanical Filter

Now that the sediment, debris, and rust are out of the picture, the water filter will start removing the smaller elements that might contaminate the water. Some filter mediums are small enough to trap most of the bacteria that pass through the water, but they will also trap some of the organic compounds that make the water smell and taste bad.

Activated Carbon Filter

The activated carbon filter is the most important medium of the filter cartridge. The activated carbon presents a lot of porosities – nooks and crannies that can hold the contaminants. When the water passes through the activated carbon filter, most of the remaining elements floating through the water, including chlorine, volatile organic compounds, some pharmaceuticals, pesticides, and herbicides will be trapped by the filter’s surface.

Tips to Maintain Your Refrigerator Water Filter

No water filter can work forever even if you clean your water filter regularly. And that’s because of the filter’s design and construction. We’re going to break this refrigerator maintenance process down for you, so it will be easier to understand.

Why Do I Need To Replace My Fridge Filter?

Mechanical Filters Lifespan

The mechanical filters, no matter how many of them the fridge filter uses, have a limited lifespan. These filters allow the water to flow through its pores. The pores are specially designed to allow the water to pass undisturbed, but to trap different elements in the water.
Imagine the filter as a huge fishing net with tiny holes. As the water passes, the sediment, rust, debris, bacteria, and parasites get stuck in the pores. But when an element gets stuck in the hole, that hole will no longer be functional.

Certainly, there are other holes the water can use to pass. However, they have the same size as the first one, and they will gradually capture contaminants and get stuck as well.
Eventually, so many holes will be blocked by bacteria, rust, and other contaminants that the water will have a hard time getting through the net. Also, you will notice this as the water will slowly but surely losing its pressure. Even if you might not notice the pressure difference, you will surely notice a difference in the water’s taste and odor.

Activated Carbon Filters Lifespan

Just like the mechanical filters, activated carbon also has a limited lifespan. The activated carbon is treated with oxygen, and that makes its surface very uneven. In fact, the surface of the activated carbon is full of smaller and larger ditches. And in a rough equivalence, a single gram of activated carbon is the equivalent of up to 3,000 square meters.

Now, when the chlorine, pharmaceuticals, pesticides, and herbicides reach the activated carbon medium, they will be attracted by the carbon molecules, and they will be trapped in the ditches on the carbon’s surface. But as the water flows through the activated carbon, more and more of its ditches will be filled with elements, so that they won’t retain new ones.

When this happens, the carbon filter will stop filtering, and you might feel the higher amount of chlorine in the water’s taste and smell.

When Do I Need To Replace My Fridge Filter?

Refrigerator Water Filter installationThe short answer is when the manufacturer recommends it. If you wait until you notice a difference in the fridge’s water pressure or a change in the water’s taste, it might be too late to be efficient. Every water filter has to pass some tests before it reaches the market. During these tests, the manufacturers calculate how long they can use the filter efficiently.

Now, depending on their results, the timeframe and capacity can vary. Some models might filter up to 500 gallons of water, while others might filter 3,000. Some can be used for up to 6 months, while others can be used for up to 3 years.

We recommend you read the manufacturer’s instructions and use a sharpie to write the filter’s expiring date on the filter itself or on the side of the fridge so you will remember to change it when it’s time to in case you do not know how often you should change the water filter in the refrigerator.

How Do I Find The Right Filter For My Fridge?

Finding the right filter for your fridge can be surprisingly easy, and you can do it in different ways. One way you can do it is to contact the manufacturer’s customer service support and ask. Another way to do it is to check your fridge’s specifications and see the thickness of the waterline. Most water filters have a universal design, and as long as the filter matches the waterline, it will match your fridge. The third way is to use the part finder query box some manufacturers use and verify if your fridge’s model is listed there.

How Do I Install My New Refrigerator Filter?

Replacing a refrigerator water filter is easy. Most models come with all the accessories you need for the installation, and you don’t need to use any tools or have special training to do it.

The first thing you should do is to read the manufacturer’s installation instructions. After you read and understand the instructions, stop the water supply for the line that leads to the fridge. Once you do that, disconnect the fridge from the waterline, attach the filter’s quick-connect lines, and prime the filter before reattaching the waterline. To prime the filter, you will need to start the water line’s supply and let the filter work for up to 10 minutes, depending on the model. You can use a bucket to prime the filter. Now reattach the water line to the fridge. After the filter is connected, you can use the fridge’s water tap.
