How to Flush Your Refrigerator Water Filter

How to Flush Your Refrigerator Water FilterYour mom and dad taught you to flush the toilet, right? But who taught you to ”flush” your new refrigerator water filter after initial installation? Chances are – no one did.

What Does Flushing Mean?

Flushing your filter simply means to run water through it several times before using the filter for consumption. No tools or equipment is needed to flush the filter, only a container to empty the water into.

Why Do You Need to Flush The Filter?

Your refrigerator water filter is made out of a carbon media block that is formed to fit your specific filter shape. With a properly installed water filter, your water runs through this block to filter out any contaminants and particles picked up prior to entering your refrigerator. By doing so, water is safe for drinking and tastes clean.

However, manufacturing and shipping causes carbon particles in the media block to knock loose. This means that the first few glasses of water most likely contain these bits, causing water to look gray and cloudy. While consuming this water won’t hurt you, most people would probably prefer not to drink it. To save yourself the hassle, you should flush your new refrigerator water filter.

How to Flush the Filter?

You should always check the owner’s manual for your specific refrigerator water filter to make sure that you are following all installation and set-up properly. Most manufacturers’ recommend that you run between three to five gallons of water through your refrigerator water filter before consumption. For refrigerators that don’t dispense water, discard the first two batches of ice. Remember, these carbon particles can also get frozen in your ice cubes.

    • Hello Don,
      Thanks for the question! The change filter light is just a timer that needs to be reset. Most refrigerators require you to hold down the reset button for about 5-10 seconds. The process can vary based on refrigerator brands so check out our other post Refrigerator Filter Change Light Still On? for more specific instructions.

    • Linda,
      You only need to flush a refrigerator filter right after your install it. After the new filter is inside, you should take a container or large cup and empty between 3-5 gallons of water into it. You will want to just dispose of that water. This should rid the filter of any extra particles that shouldn’t be there. After flushing it, your water should taste normal.

      Hope this helps,
