What Do Activated Carbon Filters Remove from Water?

The activated carbon filters can remove common chemical pollutants, including chlorine, herbicides, pesticides, pharmaceuticals, industrial solvents, and volatile organic compounds (VOCs). They also reduce turbidity, foul odor, color, and water taste.

It is important to note that activated carbon filters will not remove all contaminants from the water; more advanced filtration systems are needed. However, it works well in reducing the most common impurities in drinking water. It is also relatively easy and inexpensive to maintain. For these reasons, activated carbon filters are popular for home water filtration systems.

What Is an Activated Carbon Filter?

Activated Carbon Filter is a type of water filtration technology that uses activated carbon to filter water. Activated carbon is a form of carbon that has been processed to have tiny, low-volume pores that increase the surface area available for adsorption or chemical reactions. Activated Carbon Filters are commonly used in many residential and commercial water filtration systems because they can remove many contaminants from water.

Activated Carbon Filters can remove various contaminants, including chlorine and its byproducts (chloramines and trihalomethanes), organic compounds such as pesticides, solvents, herbicides, industrial chemicals, tastes and odors, and volatile organic compounds (VOCs). The carbon in these filters also helps reduce the level of lead, mercury, and other heavy metals that may be present in water.

How Do Activated Carbon Filters Work?

Activated carbon filters are composed of tiny carbon particles, usually coal or wood-based. These particles have been treated to increase their surface area and porosity, which increases their ability to absorb impurities from the water that passes through them. As the water moves through the filter, contaminants such as chlorine, chloramine, toxins, bacteria, and metals are trapped in the carbon particles. The result is cleaner, better-tasting water that is safe for consumption. Activated carbon filters also effectively remove sediment and other particulates from the water, making them ideal for treating well or surface water sources with high sediment and turbidity levels.


Do Activate Carbon Filters Need Replacement?

Activated carbon filters require periodic replacement to ensure that they remain effective. Depending on the type and quality of the filter, it may need to be replaced every few months or as often as once a year. The frequency of filter replacement will depend on the amount of water being filtered and should be checked regularly to ensure that your water is properly filtered. In addition, certain activated carbon filters may require additional maintenance, such as backwashing or flushing.

What Do Activated Carbon Filters Remove from Water?

Rs can also reduce Perfluorooctanesulfonic acid (PFOS), an artificial chemical used in many consumer products. PFOS is resistant to standard water treatment processes and can remain persistent in surface waters for many years, leading to potential health concerns. Activated carbon filtration systems can help remove PFOS from drinking water, helping to protect public health and the environment.

  • Chlorine (Cl): Chlorine is the most common chemical used to treat municipal water. Activated carbon filters can effectively remove chlorine from drinking water, leaving it safe and odorless.
  • Chlorine bi-products: Chlorine is often added to public water supplies but doesn’t permanently eliminate specific health-threatening contaminants. Chlorine can react to organic material in water and create hazardous chloroform. Activated carbon filters help remove chlorine by-products such as trihalomethanes (THMs) and haloacetic acids (HAAs).
  • Chloride (Cl-): Activated carbon filters can remove chloride from water. Chloride is one of the most commonly found dissolved ions in water and is often present due to runoff, sewerage systems, and industrial discharges. Activated carbon filters trap chloride molecules and remove them from the water supply.
  • Pesticides: Activated carbon filters effectively remove a wide range of pesticides from water, such as herbicides and insecticides. These compounds can be challenging to remove from drinking water sources since they have an affinity for attaching to organic particles that make up much of the water matrix. Activated carbon filters provide a reliable way to remove these pollutants from drinking water.
  • Herbicides: Activated carbon filters are effective at removing herbicides from water. Herbicides can adversely affect human and animal health when ingested, so it is essential to ensure they are filtered out. Activated carbon filters help reduce the risk of consuming these dangerous chemicals by trapping them in the filter media and preventing them from entering drinking water supplies. Water is safe and free of potentially hazardous substances.
  • Nitrate: Activated carbon filters effectively remove nitrate, a chemical found in fertilizers and sewage. Nitrate is highly soluble in water and can easily contaminate groundwater and drinking supplies, potentially harming human health.
  • PFOS: Activated carbon filter Phosphate: Phosphates are a common pollutant in water. They come from fertilizer, detergents, and sewage effluent. Activated carbon filters can help reduce phosphates which helps prevent algal blooms and eutrophication in rivers and lakes.

  • Lithium: activated carbon is a type of activated carbon filter used to remove metal ions from water. It works by bonding with positively charged ions such as lithium and trapping them in the activated carbon, allowing for safe removal from the water supply. This type of filter can also be used to reduce scaling buildup caused by calcium or magnesium deposits in hard water.
  • Pharmaceuticals: Activated carbon filters can remove many pharmaceuticals from water. In particular, carbon filters can remove antibiotics, hormones, and steroids. They are also effective in removing many sweeteners and other chemicals found in drinking water. Additionally, activated carbon filters can reduce the levels of chlorination byproducts called trihalomethanes (THMs) that can be found in water.
  • Microplastics: Activated carbon filters are effective in trapping microplastics. These tiny pieces of plastic, often measuring just a few microns in diameter, are found in our water supplies and can cause health risks if ingested. Activated carbon filters can remove most of these contaminants from your drinking water.


Are All Activated Carbon Filters The Same?

No, activated carbon filters have different levels of efficacy. The size of the particles and the amount of time water is exposed to the filter play a significant role in how effective it will be at removing specific contaminants. For example, fine particles such as microorganisms may require more time for filtration, while larger suspended solids can be removed in a shorter time. Additionally, activated carbon filters can contain different media types, such as granular activated carbon (GAC) and powdered block activated carbon (PBC). GAC is effective at removing organic molecules, chlorine, and odors from water, while PBC is better at adsorbing other substances, such as heavy metals or radionuclides.
