How to Remove Activated Carbon From Filter – Step by Step

You know, removing activated carbon from a filter is easy, but are you doing it properly? Activated carbon keeps the water free from different impurities and toxic materials. 

But, when you use the same activated carbon for a long time, it can’t complete its activities as before. That’s why you need to change this after a certain time.

Hence, I am here to suggest to you the steps of how to remove the activated carbon from the filter, the necessity of removing and indications using which you can understand that your activated carbon should be changed.

8 Steps to Remove Activated Carbon from Filter

Though I believe that removing activated carbon from filters is an easy process, hobbyists may face several problems in this prospect. The new hobbyists especially suffer much.

Hence, I will try to depict the way of removing activated carbon step by step to make it easy enough for you.

Step-1: Turn off the filtration system

At first disconnect the filter system from the power source. It is maintained to ensure safety during the process.

Step-2: Open the filter 

Open the filter compartment or container to access the activated carbon media. This step may vary depending on the type of filter you have. You can check the manufacturer’s instructions for guidance.

Step-3: Scoop out the activated carbon 

Next, you have to carefully scoop out the activated carbon. You can use a clean spoon or a suitable tool for extraction purposes. 

Step-4: Place the removed carbon

After that, place the removed carbon in a sealed container as a disposal mechanism. You can check with your local waste disposal regulations. 

In this way, you can get an idea for guidance on how to handle and dispose of it correctly. It is important to prevent dust and spills.

Step-5: Clean the excess carbon

If there is a significant amount of carbon left, use a vacuum cleaner with a brush attachment to clean the filter housing. You should complete the process before reassembling the filter. 

Step-6: Clean the filter

Clean the interior of the filter housing to remove any debris or unwanted toxicants present in the filter.

Step-7: Restore the new one

Once the filter housing is clean, you can discard the used activated carbon. Else, you can replace it with new media. But you should select the new one depending on the type of filter you are using.

Then, you should securely close the filter. It must be maintained that the housing is properly sealed. Otherwise, it will turn devastating. 

Step-8: Reconnecting the filter

Reconnect the system with the power source. Remember to follow any specific instructions provided by the filter manufacturer for the safe and proper removal of the activated carbon.

Why Remove Activated Carbon from Filter

After getting the answer of how to remove activated carbon from a filter, a question might hit your head and that is why should I learn to remove activated carbon? 

Let me explain it properly. Removing activated carbon from a filter may be necessary for various reasons. First of all, over time, the activated carbon in the filter can become saturated with impurities. 

As it is working for a certain period, such impurities are quite normal. But for this reason, this matter reduces its effectiveness in adsorbing pollutants and odors. 

You know that you are using activated carbon for diminishing pollutants. If this purpose is not fulfilled, then using the material will be of no use for the filter. 

In this case, replacing the activated carbon helps to maintain the filter’s efficiency and ensures that it continues to provide clean and fresh air or water. 

Additionally, removing and replacing activated carbon allows for proper maintenance and prevents potential contamination from accumulated pollutants. 

Surely, to maintain the filter’s efficiency, you have to remove or replace the activated carbon periodically and replace it with fresh activated carbon. 

Otherwise, the filter will become less efficient at removing impurities and the contaminants may start to bypass the filter, potentially causing issues and compromising the filtration system’s performance. 

When Should I Remove Activated Carbon from Filter? 

Following the upper portions, I should now mention the periodic cycle of activated carbon removal. But before mentioning the fact, I want to notify the factors that regulate activated carbon. 

However, the frequency of abrogating activated carbon from a filter depends on the type of filter and its usage. The usage frequency makes the variation in repealing time.

Also, contact time, temperature, flow rate, adsorbate concentration, and the properties of the activated carbon, such as pore size and surface area determine the carbon filter time. 

Additionally, the nature of the adsorbate and the presence of other substances in the environment can also impact the effectiveness of activated carbon for removal purposes as I experienced.

From that point of view, I will recommend replacing activated carbon every 2-4 weeks in aquarium filters to maintain its effectiveness. 

However, for air purifiers and other filtration systems, manufacturers usually provide specific guidelines in their user manuals. That’s why I will refer to the product’s instructions or guidelines for the best recommendation.

Can I Clean an Activated Carbon Water Filter?

In the case of replacing activated carbon, I always face the question of whether there is an alternative to removing activated carbon. That means, can the same activated carbon be used after cleaning without changing?  

Well, activated carbon filters can indeed be cleaned to some extent, but there is a problem. These materials are not designed for extensive cleaning and are generally considered disposable. 

Often, the activated carbon can’t provide the same perfect service after cleaning when you are using the same material for a long period. Hence, it’s better to replace it.

However, if you want to go for a regular light cleaning procedure, you might involve gently rinsing the filter with water to remove dust and debris.

It is worth mentioning that aggressive cleaning or using chemicals could damage the filter, reducing its effectiveness. That’s why it is usually more practical to replace the filter when it becomes clogged or less effective.

Signs that Indicate Your Activated Carbon Need to be Changed

Along with time duration, you will get some indications too in your filter when the activated carbon will need to be changed. Here are those indications that I found in my filter.

  • Reduced water flow or slow filtration. This is the most common symptom that I experienced in my filters along with my friends.
  • Foul odor or taste in the water. 
  • Discoloration or cloudiness of the water. This makes the water look unhygienic. 
  • Difficulty maintaining water quality or clarity in an aquarium leads to the death of the fish and other inhabitants. 
  • The presence of impurities, chemicals, or contaminants in the water. Sometimes, toxicants are also produced. 
  • Increased levels of chlorine or other chemicals in the water.
  • The expiration date of the activated carbon has passed. After this duration, using activated carbon can be harmful.


Can I reuse activated carbon after removing it from the filter?

Yes, you can do so, but under certain periods. You can rinse the activated carbon with clean water and let it dry completely before reusing it. But, keep in mind that activated carbon loses its effectiveness over time due to its lifespan.

Are there any precautions while handling activated carbon?

Yeah! I will suggest you use protective gloves and avoid inhaling the dust as well as follow the manufacturer’s instructions for safe activities and disposal. 

Is there a specific disposal method for using activated carbon?

Yes, but it will vary according to your locality. Check local regulations for hazardous waste disposal or recycling centers that may help you to handle activated carbon.

Final Thoughts 

Hence, I have reached the final point of my detailed discussion. Removing activated carbon after a certain time is not only beneficial but also mandatory. 

Also, this part becomes more fruitful for your tank when you complete the process the right way. To clear up your confusion, I have mentioned these small things too that I apply in the case of my filter. 

Hopefully, it will benefit you properly. If you have more questions on this topic, feel free to ask me. Or, search the various topics about the nutrient levels mentioned on my websites.
