What do Activated Carbon Filters Remove?

  • Do water filters work? The short answer is yes! Water filters are highly effective at filtering contaminated water. The effectiveness of the water filter depends on what contaminants are in the water and what type of filtration method is used. activated carbon pellets bulk


    Tap water may contain contaminants that you may not want to consume, which is why many people turn to water filtration systems. The water coming from your tap may contain levels of impurities that violate long-standing regulations put forth in the 1974 Safe Drinking Act. Not all tap water in the United States is poor quality containing harmful contaminants, but understanding if yours is and how to treat it is important.


    Different types of filtration systems remove different types of contaminants. Because of this, many water filtration systems combine different filtration methods to capture a broad array of contaminants and remove impurities.


    Reverse Osmosis

    Reverse osmosis (RO) is one of the most effective methods to reduce harmful bacteria and produce safe drinking water  In an RO system, contaminated water is forced through a membrane that contains very small pores. The pores are small enough to let through water molecules, but not large enough to let through other solids and particles.


    Reverse osmosis systems are great at removing substances that are larger than a water molecule, including sodium, nitrates, and the mineral and metal ions like calcium carbonate and lead that contribute to water hardness. RO systems are less effective at removing any other contaminant whether that be bacteria or chlorine.


    Activated Carbon

    Activated carbon is a type of charcoal that has been treated with oxygen to increase the surface area of the carbon. As water passes through activated carbon water filters it attracts and traps any contaminant or impurity that exists.


    Activated carbon water filters are effective at removing disinfectants, pesticides, and industrial solvents. This filtration method is also used to remove bad odors and taste from the water. Activated carbon water filters are less effective at removing the mineral ions that contribute to water hardness, sodium, fluorine, and nitrates.



    Ion-exchange systems are often referred to as water softening systems because they are used to remove the mineral ions and metals that contribute to water hardness. These systems contain a tank filled with negatively charged resin beads. As water flows over the resin beads, the mineral ions attached to the water molecule are attracted to the resin and replaced with sodium ions.


    Ion-exchange systems are effective at removing mineral ions and heavy metals from water, but they won’t remove disinfectants used in water treatment, sediment, fluorine, or industrial chemicals and
