Activated carbon typically lasts for 6-12 months in a water filter, depending on usage and quality of water. Activated carbon is a widely used filtration medium that is used to remove impurities from water.
It is usually in the form of small pellets or powder and is made from carbon-rich materials like coal, coconut shells, or wood. Its highly porous nature makes it ideal for trapping contaminants like chlorine, sediment, and volatile organic compounds from water.
However, over time, the activated carbon gets saturated with pollutants and loses its effectiveness. That’s why it is crucial to change the activated carbon periodically to maintain the quality of water. In this article, we will explore the lifespan of activated carbon in water filters and provide tips on when and how to replace it.
What Is Activated Carbon And How Does It Work?
Activated carbon water filters are becoming increasingly popular in households. Have you ever wondered what activated carbon is and how it works? We will discuss the definition of activated carbon, the differences between activated carbon and regular carbon, the process of activating carbon, and how activated carbon works in water filtration.
Definition Of Activated Carbon
Activated carbon, also known as activated charcoal, is a form of carbon that has been processed to have small, low-volume pores that increase its surface area and make it highly adsorbent. This means that activated carbon is capable of trapping impurities and contaminants from water.
Differences Between Activated Carbon And Regular Carbon
There are some differences between activated carbon and regular carbon that make activated carbon a better adsorbent material. Here are some of those differences:
- Surface area: Activated carbon has a much larger surface area compared to regular carbon due to its small, low-volume pores.
- Pore size distribution: Activated carbon has a wide variety of pore sizes, which makes it more versatile than regular carbon.
- Level of purity: Activated carbon is more pure than regular carbon since it goes through an activation process that removes impurities.
The Process Of Activating Carbon
The process of activating carbon involves subjecting it to high temperatures, typically between 600-1200 degrees celsius. This process removes impurities and increases the surface area of the carbon. There are two types of activation processes:
- Chemical activation: In this process, carbon is mixed with a chemical activator, such as phosphoric acid, to create the pores.
- Physical activation: In this process, carbon is subjected to high temperatures in the presence of an inert gas, such as nitrogen, which creates the pores.
How Activated Carbon Works In Water Filtration
Activated carbon works by adsorbing impurities and contaminants from water as it passes through the filter. Here’s how it works:
- Organic matter and chemicals stick to the surface of the activated carbon due to its high surface area and attraction to organic compounds.
- As water passes through the filter, activated carbon traps these contaminants in its pores, leaving clean, purified water to pass through.
- Over time, the activated carbon becomes saturated and loses its effectiveness, requiring replacement. The lifespan of activated carbon filters varies from filter to filter, but typically lasts around 6 months to a year.
Activated carbon is an effective water filtration material due to its high surface area, wide range of pore sizes, and low impurity levels. By removing contaminants and impurities from water, activated carbon filters provide clean, safe drinking water.

Myth: All Activated Carbon Filters Are The Same
Another common misconception about activated carbon filters is that they are all the same. However, this is far from the truth. Activated carbon filters differ in quality, size, and the type of organic material used to make them. Some may filter out only specific types of impurities, while others can remove various impurities from water, including chlorine, pesticides, and other chemicals.
If you want to obtain the best results from an activated carbon filter, you need to select the right one based on your needs. Determine the impurities you want to remove from your water, and then choose the filter that is most suitable for that.
Myth: Boiling Water Can Recharge Exhausted Activated Carbon Filters
Some people believe that boiling water can recharge activated carbon filters that have become saturated. However, this is another fallacy. Once an activated carbon filter becomes saturated, boiling water will not recharge it. Boiling water only kills microorganisms present in the water, it won’t remove impurities.
The best approach to deal with exhausted activated carbon filters is to replace them as soon as possible to ensure that you continue to consume pure, clean water.
It pays to be wary of the common misconceptions about activated carbon filters. Remember, activated carbon filters don’t last forever, some are higher quality than others, and boiling water will not recharge them. If you want to ensure that you continue to drink clean, safe water, it’s crucial to replace activated carbon filters periodically as recommended by the manufacturer.
