How Often Should I Change My Refrigerator’s Water Filter

A refrigerator water filter is an integral component of any home's water filtration system. This filter extracts impurities (such as chlorine, sediment, and bacteria), ensuring that the water and ice you make use of are clean and safe to drink.Like all filters, a refrigerator water filter ought to be replaced regularly to continue to operate properly. In general, it’s recommended that you replace your refrigerator water filter every six months to one year. The reason is that, over time, the filter can become clogged with impurities; consequently, it loses its effectiveness and may allow harmful contaminants to pass through. We don’t want that, do we?

How Often Should I Replace My Refrigerator’s Water Filter? 

When to replace your water filter can depend on how much water you use, how many people live in your home, and the quality of your water. These guidelines will help you decide when is the right time for a new filter:

  • Six months if you have city water
  • Nine months if you have well water
  • Four to six months if you have hard water 

On the other hand, some refrigerators come with built-in filtration systems, such as a water dispenser or an ice maker. In this case, it doesn’t mean the filter will last you a lifetime; you still need to replace the filter according to the manufacturer's recommendations.

Keep in mind that the replacement frequency can differ depending on the specific model and type of filter.


Maintain the hygiene of your refrigerator, both internally and externally, as well as the water dispenser and ice maker too. 

This cleaning process isn’t only crucial for the longevity of your filter, but also ensures that the water and ice you consume are of the highest quality. 

When Should I Replace My Refrigerator’s Water Filter?

If you come across any changes in the taste, odor, or appearance of the water or ice, it may be time to replace your refrigerator's filter.

Likewise, if you have a sizable household that consumes a large amount of water, you may need to replace your filter more frequently as well. Not to forget that different filters will have different filter ratings as well. 

Often, a filter will be tagged with its certification as a standard 42 or 53 rating. 

You're probably wondering what a filter rating does. In a nutshell, the rating provides a clear indication of its effectiveness and helps determine when it’s time to change it.

Another important note: Guarantee that you purchase a compatible filter with your specific refrigerator model.

  3. Remove the old filter by either twisting it off or releasing any locking mechanisms (this depends on your refrigerator's model).
  4. Install the new filter. Cautiously insert the new filter into the designated housing. Make sure, too, that it’s properly aligned and that the O-rings or gaskets are in place.
  5. Run water through the new filter for about 5 minutes to flush out any carbon dust or debris that may be inside.
  6. Check for any leaks before closing everything back up around the filter housing. In case everything is sealed properly and no leaks or dribbles are present, you're good to go.
  7. Sit back, have a glass of water, and celebrate the accomplishment. You installed it yourself and your refrigerator now has a new clean filter.

By following these guidelines and keeping your refrigerator clean, you can ensure that your water and ice remain safe to drink.
