Carbon filters are a popular choice for people looking to improve the taste and odor of their water. Carbon is also used in air purifiers, and it can be an effective filtration material for both water and air.
Now, the question is, can you wash and reuse a carbon water filter or you have to replace the whole filter every time?
The short answer is yes, you can. Carbon filters are durable and can be washed, reused, and reinstalled for multiple cycles of filtration.
However, it is important to note that the filtering efficiency of a carbon filter will decline with each cycle, meaning that you may need to replace it after a few cycles of washing and reuse.
I will explain this in the next few steps, but I will keep it as brief as possible.
Exactly Why Do We Need to Use Carbon Filters?
Carbon filters are mainly used to remove small particles, contaminants and chemicals that cause odors, off-flavors, and other unwanted characteristics in water and air. These particles and chemicals are known as volatile organic compounds (VOCs).
To put it simply, a carbon filter has pores that are much smaller than any filter material, so it can trap particles as small as 0.5 microns.
It has many other uses including:
- Decontaminating water by removing chlorine.
- The removal of harmful substances that can make people sick.
- Reduction of pollutants in the air.
- Enhancing water taste.
- Removing odors from the air.
Why Is It Necessary to Clean Water Filters?
When carbon filters are used for a long time, they become clogged with particles and chemicals. This reduces the filtration efficiency of the filter, making it less effective.
Also, if the filter is not cleaned regularly, the trapped chemicals and particles can start to decompose and create more odors and off flavors in the water.
Cleaning carbon filters also help to remove any media that may have built up on the surface of the filter. This buildup can block the pores and reduce the overall performance of the filter.
If a sediment filter is clogged, it may not be able to capture particles that are larger than the size of the pores in the filter.
Most importantly, the amount of flow rate and pressure drop in the filter can also be affected by a buildup of media.
9 Steps to Clean The Carbon Filter at Home To Reuse it
In other words how would you reactivate the carbon back to it’s original form at home? Cleaning a water-filtering carbon filter is easy. All you need to do is follow these simple steps :
- Turn off the water supply to the filter and the water supply after the filter to depressurize the filter housing.
- Take the filter out of your filter housing, and use a soft brush to loosen any debris that has been trapped in the pores of the filter.
- Rinse the filter with clean water to remove any loosened particles.
- Soak the filter in a solution of dishwashing liquid and distilled water for about 15 minutes. This will aid in releasing any chemicals that have become trapped in the filter media.
- Shake the filter to get rid of any loose particles. Shake it until no more dirt or debris comes out.
- Make sure to give the filter a good rinse with clean water. Read here if you can use hot water to clean the filter.
- Clean the filter housing using a soft brush and warm, soapy water.
- This one is most important, allow the carbon to dry completely before putting it back in its housing or container.
- Reinstall the filter back into the housing and turn on the water supply.
A reminder: This is a general outline of the process for reactivating carbon. The specific instructions may vary depending on the type of carbon and the method being used. It is important to refer to the manufacturer’s instructions for the exact steps to follow.
You should only clean the filters two or three times. Then should swap out the old filter with a new one to ensure maximum filtration efficiency.
How Can You Tell If Your Carbon filter is Reusable or Not?
This is often confusing to people.
The fact is, you can tell if your carbon filter is reusable or not by looking at the manufacturer’s instructions. Most filters will have a maximum number of cycles that they can be used for.
Also, the filter’s efficiency will start to decline after a certain number of cycles. If the filter is still able to efficiently remove impurities from the water after a number of cycles, then it is reusable.
Besides, it could be time to get a new filter if you discover that your current one is not performing as well as it once did.
You should also check the manufacturer’s instructions for any specific cleaning or maintenance instructions. As a result, you can make sure your filter is operating safely and efficiently for as long as possible.
Can You Wash and Reuse the Carbon Water Filter If It’s Not Dirty Yet?
Carbon filters are designed to be used multiple times before they need to be replaced.
However, if the filter is not dirty yet, it is recommended to periodically clean it with a soft brush and warm water. This will help to remove anything that might be on the surface of the filter.
It’s vital to remember that after a certain number of cycles, a filter’s filtration efficiency begins to deteriorate. Even if there are no symptoms of degradation, it is normally suggested to change the filter after a set number of cycles.
Should You Use Vinegar to Clean a Water Filter?
Yes, vinegar may be a viable alternative. Because of its acidic properties, vinegar can help to break down dirt and debris within the filter pores.
Only use white distilled vinegar that has been diluted with an equal amount of clean water. Soak the filter for 15-20 minutes, then rinse it off with clean water.
It is important to note that vinegar may have an adverse effect on certain filters. For example, it can corrode metal filter housings. For this reason, it is essential to check the manufacturer’s instructions before using vinegar to clean your filter.
Can You Recycle Used Carbon Water Filters or Throw Them Away?
Many cities offer filter recycling programs where you can drop off your used filter. It is a great way to be kind to the environment.
You can also keep your filter around and use it for things like dust collection, gardening, or other household uses.
Besides, most manufacturers or retailers offer a recycling program for used filters, so check with them to see what options are available.
The best way to dispose of your filter if you can’t find a recycling program is to put it in the regular garbage. Make sure to break it down as much as possible before disposing of it, so that the filter does not end up in a landfill.
Is It Better to Clean Instead of Replace?
You need to think about the type of filter you have and the amount of use it gets.
Generally speaking, if your filter is not heavily used, then cleaning it should be sufficient. However, if your filter is used frequently, then it’s best to replace it.
In some cases, you may find that cleaning your filter will take too much time or won’t do the job that is needed.If this occurs, you will likely need to get a new filter.
It might be cheaper to replace the water filter cartridge two times each year rather than trying to clean it every month. This is because the filter cartridge is not much more expensive than the cleaning supplies.
Ultimately, it is your decision to clean or replace your carbon water filter. Consider all the factors mentioned above and decide what is best for your situation.
If you’re unsure of what to do, it’s always a good idea to consult with you manufacturer.
Clean Only When Necessary
Cleaning and reusing a carbon filter can be an effective way to save money. However, as I noted before, cleaning your filter too frequently can reduce its effectiveness.
The key to extending the life of your filter is to only clean it when necessary and follow specific cleaning instructions provided by the manufacturer.
You may need to clean your filter if you notice any of these issues:
- Low water pressure.
- Poor taste or bleach smell in the water.
- Loud noises coming from the filter.
- A change in the water’s color.
- The filter’s performance decreases over time.
