How to Change a Fridge Water Filter: Step-by-Step Guide for Fresh, Clean Water

Is your refrigerator water tasting strange or dispensing slowly? It may be time to replace your fridge water filter. A properly functioning water filter is essential for removing bacteria, rust, and sediment from your drinking water—ensuring both great taste and health.

In this guide, we’ll show you how to find and replace your fridge’s water filter, understand different filter types, know when it’s time to change it, and provide maintenance tips. We’ll also let you know when it’s time to call MasterFix Appliance Repair Service for professional help.

Why Is Changing Your Fridge Water Filter Important?

Your refrigerator’s water filter helps remove harmful particles like chlorine, rust, and dirt, ensuring clean and fresh-tasting water and ice. Over time, the filter becomes saturated and less effective, which can lead to:

• Foul-tasting or smelly water

• Slow or weak water flow

• Cloudy or speckled ice

• Increased strain on your fridge’s water system

Replacing the filter regularly keeps water quality high and helps maintain your appliance’s performance.

When Should You Change Your Refrigerator Water Filter?

Most manufacturers recommend replacing the water filter every six months, but you may need to do it sooner if you notice:

• Bad-tasting or smelly water

• Black specks or cloudiness in water or ice

• The water filter indicator light turns on

• More than a year has passed since the last replacement

• Reduced or stopped water flow from the dispenser

Always follow your fridge’s built-in indicator or manual guidelines for optimal timing.

Where Is the Refrigerator Water Filter Located?

Common filter locations include:

• Inside the fridge, in the upper right corner or side wall

• Behind the grille at the base

• At the back of the refrigerator

• Underneath or behind the fridge (for inline filters)

Check your owner’s manual or the manufacturer’s website to find the exact filter location for your model.
