The Ultimate Guide to Carbon Water Filter Lifespan


What Is A Carbon Water Filter?

Definition And Explanation Of Carbon Water Filters

A carbon water filter is a type of water filtration system that uses carbon, also known as activated charcoal, to remove impurities and contaminants from drinking water. The filter works by attracting and trapping pollutants through adsorption, a process that harnesses the ability of carbon to bind with impurities.

When water passes through the filter, the carbon captures toxins, chemicals, and other contaminants, leaving behind clean and safe drinking water.
