How Does My Filter Work?

The filtration process occurs every time you get water from your refrigerator. Water runs from your home’s supply into the filter. As the water is pushed through the filter’s4396508 Water Filter diagram inner chamber, it comes into contact with the filtering substance, activated carbon. Activated carbon is a form of carbon specially designed to work as a filter. This form of carbon is used in most water filters as well as different types of air filters. Activated carbon is made up of millions of little pores that allow the water to seep through. Due to the carbon’s special properties, impurities such as chlorine are attracted to its surface and get trapped there. So in a matter of seconds, unfiltered tap water turns into clean, better tasting water.

The L400 refrigerator water filter is best at removing the taste and odor of chlorine in you tap water. Your city’s water treatment plant most likely uses chlorine to rid the public water supply of waterborne pathogens. While the amount you drink is completely harmless, it’s not exactly what you want to taste when you want a refreshing cup of water. The chlorine in your water supply is most likely responsible for that weird “tap water taste” that everyone complains about.

How Long Does My Filter Last?

After months of use, the carbon block in your filter will start to degrade and become saturated with impurities. This can lower the quality of your water, and if not replaced soon enough, can lead to maintenance and health issues. This is why we recommend replacing your fridge filter at least two times each year. We make replacement convenient by offering packs of multiple filters and sending friendly filter change reminders after six months go by.
