At Isopure Water, we know that good water starts with a clean fridge filter. Over time, these filters get clogged with sediment, chlorine, and impurities, affecting your drinking water's purity and taste. Changing your refrigerator water filter routinely will enable you and your family to have access to freshly purified water.

In this guide we will walk you through how to change a fridge filter, how often to replace it, and choosing a correct replacement filter for your refrigerator.


Why It’s Necessary to Replace Your Refrigerator Water Filter

The water and ice dispenser in your refrigerator uses a built-in filtering system to eliminate sediment, heavy metals, and chlorine from your tap water. After a while, though, the filter accumulates impurities, and its efficiency is compromised, and it may lead to:
  • Reduced water flow due to clogging
  • Bad taste or odor in drinking water and ice
  • Bacteria and pathogens that cannot be filtered 
For optimal performance, it is best to change your refrigerator water filter every 6 months, and even sooner, if you notice a decline in water quality.


How to Replace a Refrigerator Water Filter

Replacing your refrigerator water filter is a simple and quick process. To have clean and refreshing water at your fingertips at home, follow these simple steps.

Step 1: Find Your Refrigerator Water Filter

Refrigerator water filters are typically located in one of three places:
  • Inside the fridge compartment (upper right corner or bottom grille)
  • Behind a removable cover on the front of the unit
  • On the back of the refrigerator (for inline filters)
If you’re unsure of the location, check your refrigerator’s owner’s manual for exact placement.

Step 2: Turn Off the Water Supply

Before pulling off the old filter, it’s a good practice to turn off the water supply to avoid leaks. Find the water shut-off valve at the back of your fridge or beneath the sink and rotate it clockwise to cut off the supply.

Step 3: Remove Old Water Filter

Depending on your refrigerator model, your filter can be twist-in, push-button, or inline.
  • Twist-In Filters: Turn the filter counterclockwise and remove when loose.
  • Push-Button Filters: Press the eject button or push the filter.
  • Inline Filters: Disconnect the tubing and remove the filter from its housing.
Properly discard your outdated filter and prepare for installation of your new one.

Step 4: Install the New Refrigerator Water Filter

Take your new filter and remove any protective caps and seals. Insert the filter into the housing and:
  • For Twist-In Filter: Insert and screw in a clockwise direction to secure. 
  • For Push-Button Filter: Put new filter in position and press down firmly till it clicks. 
  • For Inline Filters: Secure the tubing to both ends tightly. 
Once installed, turn the water supply back on and check for any leaks.

Step 5: Flush the New Filter

To clear out trapped air and carbon particles, dispense 2-3 gallons of water prior to using your dispenser. This will keep your water from being cloudy or having small carbon particles in it.


How to Choose the Right Refrigerator Water Filter

Not all refrigerator water filters have a similar level of performance. In purchasing a replacement, make sure to:
  • Check Compatibility: Find the correct model number for your fridge.
  • Choose a High-Quality Filter: Select NSF-certified filters that meet water purity standards
  • Consider Your Water Quality: If you have hard water or high chlorine levels, select a filter with carbon block technology.

How Often Should You Change Your Refrigerator Water Filter?

We recommend that you change your refrigerator water filter at 6-month intervals, but frequency may vary based on:
  • Water Quality – Hard water and high sediment levels can clog filters faster.
  • Usage – If you use your water dispenser frequently, you may need to replace it sooner.
  • Manufacturer Recommendations – Always refer to your refrigerator’s user manual for specific guidelines.
Signs that it’s time for a replacement include slower water flow, unusual taste, and visible discoloration in your ice or water.
