Why Should You Change Your Refrigerator Water Filter?

A common question I often get is, “Why should I change my refrigerator water filter?” Some people tend to think that their filters can work as long as they want, so there’s no need to regularly replace it. Unfortunately, that’s not the truth. Here’s why.


Most refrigerator water filters on the market now employ activated carbon as their filtration medium. They work through a process called adsorption, which causes harmful contaminants to stick to their activated carbon. On activated carbon, there are a great many pores aiming to attract unwanted chemicals, particles, and bacteria in tap water passing through them.

However, as time goes by, these pores can be clogged by various harmful contaminants in tap water. If you fail to replace your filter in time, its filtration capability would be increasingly undermined. In this case, you and your family risk drinking unhealthy water which can result in major diseases.


Besides, the weird odors in your refrigerator would increase day by day if you don’t change your filter on a regular basis since its activated carbon also serves to purify the air in a confined space.

Then how often should you replace your refrigerator water filter? It is recommended by most experts and manufacturers that you should change it at least every six months or every 200-300 gallons of water. This time frame can vary based on the water quality in your locality.


To sum up, the refrigerator water filter is no perpetual motion machine; it has a limited service life. For health and safety, you need to change your filter as it approaches to its expiration date.
