By understanding these factors, you can make an informed decision when choosing the right filter for your needs. Let’s dive into the world of carbon water filters and their contaminant removal capabilities.

Contaminants Removed by Carbon Water Filters

You can learn about the contaminants that are currently being removed by carbon water filters. Carbon filters are effective in removing a wide range of contaminants, including chlorine, disinfection byproducts, pharmaceuticals, volatile organic compounds (VOCs), and perfluoroalkyl substances (PFAs). The process through which carbon filters remove these contaminants is called adsorption. Adsorption is different from absorption, as it involves contaminants adhering to the surface of the carbon rather than being absorbed into it.

The ability of carbon filters to remove contaminants is influenced by various factors, such as the size of the filter. Larger filters with more surface area have a greater capacity to trap and remove contaminants. The contact time between water and the carbon media also plays a significant role. Longer contact time allows for more thorough contaminant removal.

It is important to note that the type of carbon filter used can impact the effectiveness of contaminant removal. Granular activated carbon (GAC) filters are not as thorough as carbon block filters. Carbon block filters have a larger surface area and prevent most contaminants from passing through.

Additionally, the flow rate of the water through the filter affects its contaminant removal ability. Slower water flow provides a longer contact time with the carbon media, resulting in better contaminant removal. Filters that combine activated carbon with other media, such as KDF, ion exchange, ceramic, or activated alumina, can further enhance contaminant removal.
