Do Refrigerator Water Filters Actually Work?

A common question we often receive here at DiscountFilters.com is, “Do refrigerator water filters actually work?”

The best answer we can give to that question is, “Most definitely!” The only question left hanging is, “How?” Well, let’s start from the source.

Local water treatment plants are only legally required to remove a portion of contaminants found in water, leaving behind many particles for us to drink. Lead, rust, chlorine, and sediment are just a few of the contaminants found in tap water. Refrigerator water filters help remove many of these pollutants the water treatment plants fail to remove.

study conducted by the University of Arizona and Good Housekeeping found refrigerator water filters are one of the most effective refrigerator water filters available for removing pollutants. Fridge water filters are even more effective at removing contaminants than pitcher water filters, which many of us use at home.

Refrigerator filters for water-dispensing fridges are essential to every home. Not only do these filters remove contaminants from your drinking water, but they also remove any doubt you may have about the quality of water your family is drinking. Nobody should have to worry whether their water is safe to drink or not. Everyone should be able to rest assured knowing the water in their house is pure and healthy. Using an effective refrigerator water filter gives families one less thing to worry about.

How Do Refrigerator Water Filters Work?

You may be asking, “What exactly do the filters do? How do they clean my water?” Well, it’s actually quite simple.

Refrigerator water filters clear contaminants in the water by forcing the water through activated carbon located inside the filters. The carbon acts like a contaminant magnet trapping pollutants and particles. The end product: clean, healthy drinking water for you and your family.

That’s it. Yes, it’s really that simple.

However, much like the bags in an old Oreck vacuum, water filters can only remove so many contaminants before needing to be replaced. An overused refrigerator water filter lacks the ability to properly remove harmful substances still in the water. Once the carbon inside the fridge filter becomes completely covered with contaminants, the water passes through the filter untreated, leaving you with polluted water. Water that passes through old, overused filters can even dislodge some of the trapped pollutants back into your drinking water. Yuck! Don’t worry though, keeping your water filter up-to-date will prevent this from happening.

Dirty vs Clean Water

To sum it all up, YES! Refrigerator water filters work great as long as they’re maintained and replaced regularly. Our advice: Make sure to replace your water filter as often as your appliance owner’s manual specifies, which is usually once every 6 months. This will ensure your water remains clean, clear, healthy and tasting great. Check out some of the best water filters like the ClearChoice CLCH105!

    • It depends on the fridge type, but any tested by NSF/ANSI against Standard 53 reduce the amount of lead in the water. The best way to tell for each filter is to use our fridge filter finder to find your fridge’s filter and then check out the specifications for more information.

  1. I read all the top answers on how the water filter cleans the water.But how can the water filter on a refrigerator clean the water if the water filter as only one entrance and no exit? Please explain. Thank you

    • Hey Moises! Every fridge filter is a bit different, but most have tiny openings on the filter that takes in unfiltered water around the edge and then passes that water through the carbon block. Once the water passes through the carbon, filtered water is then pushed back to the fridge through the center opening on the same part of the filter. Hopefully this helps!

  2. what about DBPs (disinfection byproducts of chlorine and chloramine)? What about chloramine itself? Will fridge filters be adequate?
