What Do Refrigerator Water Filters Filter Out?

Hugo Totty is passionate about clothing and lifestyle. I love sharing my experiences about different fashion aspects that I've picked up.


When it comes to buying a key household appliance like a fridge, many look to fridges with a water filter. Being able to get cool, filtered water from your fridge is a nice touch – particularly for those who live in places with poor tap water.

With that in mind, you might want to think about buying a fridge that comes with a water filter. Yet before you do, it pays to know what the actual water filter will filter out in the first place. So, what do refrigerator water filters filter out? What are you going to be removing from the water if you start using a filtered source?

What Can Your Water Filter Remove From the Source?

If you are going to be using a water filter, then it is natural that you want to see it make a good job of removing excess stuff from your water. However, working out just what it actually will remove can be tough. Typically, though, a water filter will help to decontaminate your water of key problems such as:

  • Chlorine and other chemicals that reside in the water
  • Pharmaceutical products that might have come into the water
  • Heavy metals such as mercury and lead can get into our water
  • Pesticides and insecticides that can get into the water during usage
  • Organic compounds that might have grown within the presence of water
  • BPAs

These are some of the most common causes for water contamination and thus sickness. If you are someone who wants to make sure they are drinking safe water that has been stripped of these problems, then you definitely should be looking at getting a water filter for your fridge.

However, not every water filter is going to be strong enough to remove some of the above-listed issues. Some contaminants are simply too strong for all but the most powerful water filters to be able to remove. This includes lead and chromium-6, both of which are very common toxins found within water.

That being said, some water filters come with an NSF 42 certification which means the only thing it is able to remove from the water is chlorine.

What Can a Water Filter Not Remove?

One of the most common queries when looking into what do refrigerator water filters filter out is the topic of fluoride. Many people want to remove fluoride from their water for several reasons, but a water filter in your fridge is not strong enough to do this. Indeed, toxins such as arsenic, nitrate, and fluoride will not be able to be filtered from your water simply by using a fridge filter. They are simply not going to be strong enough to do that.

If you wish to remove fluoride then you would need to invest in a water filtration device that uses reverse osmosis instead. The most common water filters will look to deliver carbon filtration that removes anything that might impact on the taste and/or smell of the water. However, they likely cannot remove fluoride from your system.

For the most part, filters cannot guarantee that they can get rid of everything that could make your water dangerous to drink. This means that bacteria, chemicals, and other harmful particles might still remain within the water even after it has been run through the filter.

Keep that in mind as many people do not know this and thus assume that their water is 100% safe to drink and use moving forward. Fridge water filters cannot remove all of the potentially harmful pollutants that exist within our water; you would need something much more powerful to do this. They are designed primarily to make your water taste nice and smell appealing, not to remove every potential harmful substance – unfortunately.

Remember to Check the Longevity of Your Water Filter

When you use a refrigerator water filter, it is easy to assume that it will last forever. After all, buying a fridge with a water filter installed costs plenty of money. Many assume, then, that the water filter is going to be unlimited in terms of its usage. However, as good as this would be, this is simply not the case. for that reason, you should think about what to do when your refrigerator starts to show signs that the water filter has been, well, filtered out!

If you have this problem, then it is important that you do something about it as soon as you can. Replacing the water filter should be a priority for anyone who has a water filter in their fridge. Your water filter should typically be replaced every six months or so. Over time, they will simply begin to stop working as they should and build-up of sediment and other issues can mean the filter stops working entirely.

Regular replacement and improvement will maximise the quality of filtering that is being delivered by your system.
