Best Refrigerator Water Filters Review 2021 | How to Flush Your Refrigerator Water Filter

Refrigerator water filters provide a reliable and convenient source of cool, clean drinking water and ice. To keep the refrigerator water safe to drink, the filters need to be changed every six months with average usage. In most cases, replacing the filter is fairly simple.

However, flushing the filter before use is the most often overlooked step. Flushing is as important as replacing. You’ll get cleaner, fresher tasting water by flushing water through the filter several times. Why the filter should be flushed when it’s first installed? Let’s move on to the details.

Why flush the refrigerator water filter?

Most refrigerator water filters are made up of carbon filters which are filled with black carbon granules. The carbon is a major force to capture the particles and contaminants in the refrigerator water and enhances the taste of water and removes the odor.

However, when water runs through a newly-installed filter, it flushes out some of the carbon, thus your water may have some tiny black specks or an overall cloudy or gray color. These are some bits of loose carbon which have been separated from the carbon blocks by manufacturing or shipping. They are harmless to drink, but probably nobody wants a glass of gray water with black spots or weird taste.

How to flush the refrigerator water filter?

It is advisable to run three to five gallons of water through your fridge filter before using it for household purposes. This ensures that all the loose carbon is flushed out of the filter.

If your fridge doesn’t have a water dispenser, discard the first two buckets of ice after finished replacing, because these black spots can get frozen in the ice. Follow the steps below to flush your refrigerator water filter:

Step 1

Prepare a large pitcher or a container that fits well into the water dispenser and place a large cloth or towel (absorb the water spills) on the floor next to the refrigerator.

Step 2

Put the container under the water spout, press the dispenser button to fill the container.

How many times do you need to fill the container? To be precise, 16 cups equal a gallon. If you hold a 4-cup pitcher or measuring cup, it takes four times to make a gallon.

Step 3

Pour the water directly down the drain. You can also collect the water in a large tank for watering plants. They will benefit from these tiny black specks.

Step 4

Repeat steps 2 and 3 after running three to five gallons of water. You’d better dispense water every week to ensure a continual fresh supply.
