Do Refrigerator Water Filters Actually Work?

A common question we often receive here at 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.

Why Should I Use a Refrigerator Water Filter?

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 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 ways to remove pollutants. Fridge water filters are even more effective at removing contaminants than pitcher water filters, which many 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. Everyone should feel confident knowing the water in their home is pure and healthy, meaning there’s 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 pretty simple.

Refrigerator water filters clear contaminants 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 cannot properly remove harmful substances still in the water. Once the carbon inside the fridge filter becomes wholly 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.

Do Refrigerator Water Filters Work?

To sum it all up, YES! Refrigerator water filters work great as long as they’re maintained and replaced regularly. Here’s our advice: Make sure to replace your water filter as often as your appliance owner’s manual specifies, which is usually once every six months. This will ensure your water remains clean, clear, healthy, and tasting great.

  1. re “……. 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. ” I don’t understand how ” water passes through the filer untreated”. Also don’t understand how “…water passes through overused filters can dislodge some of the trapped pollutants back into your drinking water”. I would expect an “over used filter” to just become blocked & no longer pass water through. Perhaps there is a ‘bypass’ path allowing water to flow around the overused filter ?

  2. I have been using your filters for years. This time when I tried to insert a new filter, it would not make the final right turn to complete the change. I tried a second filter with the same results. Our floor was flooded with water on both occasions. Can you help?

  3. I could understand if it had a pass through system. But, in and out the same place? Filters for my hose in the RV, the water passes through and exits at the opposite end. Fridge enters and exits the same place.

  4. I bought a new filter for my refrigerator and the name of it is Frigidaire I replaced it about two three months ago I got a glass of water and it tasted like chlorine I don’t think that should be happening you got some answers please let me know

  5. How can you tell if the water filter is actually working? I have a Samsung RF268ABWP french door refridge that doesn’t seem to filter its water. The water’s taste is bad and when I change its filters, the replaced filters always look brand new and are completely dry. Any ideas??? Thank you!

  6. Why would I need a filter? I do not have the DOOR drinking water dispenser. I have also disconnected the ice cube maker by plugging the copper tubing, but I’M not sure that is all that needs to be done for the disconnect, More buttons to push or something? Can you help me?

    • 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.

  7. 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!

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

  9. I tried to order a replacement for my under-sink water filter. The code said 3US-AS01. I was sent a refrigerator water filter EP -WGFC2800A. Can this filter be used to replace the one under my kitchen sink?
