How a Refrigerator Water Filter Works: Everything You Need To Know

Your fridge uses water to cool your food and flush out anything it doesn’t want to be in contact with. When your fridge uses too much water, it can cause the compressor to overheat and damage the device. To prevent this, you can add a water filter to your fridge. A refrigerator water filter will help purify your home’s tap water by filtering the incoming water before reaching the dispenser or the ice-maker.

This will allow your fridge to use less water while still being able to keep foods cold. You can also use a water filter in the shower or while taking a shower in a tub of softened water first to reduce the amount of chlorine in that water.

How Does a Refrigerator Water Filter Work?

Water passes through miles of piping before reaching your home. Hence, carrying along the way many impurities like pollutants from the air, pharmaceuticals flushed into water supplies, or waste from manufacturing plants.

A water filter for your fridge is a round porous chamber that allows a little of your water to flow through the water channels and collect in it. When the water enters this chamber, the holes in the chamber begin to clog. It does not collect all the water, and the water that can’t be collected flows through the holes and out of your fridge. You can turn the faucet on and run cold water through the filter. You can use the flow of cold water to force air into the water chamber. Then you can take the sponge and brush and wash away the rust. You will need to do this several times until you notice a change in the water quality, and you can take a shower or bathe normally. A carbon block inside the filter removes sediment from the water and reduces impurities like Chlorine, Asbestos, and Lead. The carbon block is incredibly porous, and its surface area will capture microscopic substances that are potentially harmful. In addition to making the water safer, the filter also improves the smell, taste of the water and ice being dispensed.

Note: A proper filtering system will be cleaned with vinegar and water twice a year. You will have to do this every few months.

On some refrigerators, you might need to depress a tab to release a cover. Depending on your model, you can remove the old filter by rotating it counterclockwise, pushing the filter in firmly to disengage, or by pushing a release button.

Before installing your new water filter, remove the protected cap or caps from the inlet and outlet ports. If applicable, you may also need to transfer an end cover from the old filter to the new one, align the new filter with the housing and press it in firmly, or rotate it clockwise to lock it into place (if located on the inside of your fridge), close the cover if necessary and run water through the system for at least 3 minutes to flush out the lines before drinking, you can then turn the ice-maker on if applicable, and your new filter should be ready for use.
