Carbon Filters are used in hydroponics, especially in monitoring air that circulates in the hydroponic system to remove smell and other undesirable characteristics that the air may contain. These filters, however, can get blocked over some time and therefore are not very effective. When you wish to replace your carbon filter, you do not have to do so constantly since you can clean it and use it again to save money.
In this guide, it is described how to properly clean and re-use your carbon filter while still benefiting from its performance.
Why Cleaning Your Carbon Filter Matters
A blocked carbon filter hampers air circulation and also weakens its capacity to filter the air in your hydroponic system. Regular cleaning can:
- Increase filtration capacity.
- Maximize the time you have with your filter.
- Ensure that your hydroponic plants are healthy in general.
Signs Your Carbon Filter Needs Cleaning
Look for reduced airflow, a noticeable odor in your grow space, or excessive dust on the filter. These signs indicate the filter is clogged and needs attention.
- Decreased filtration rate of the filter.
- An obvious smell coming out of the filter.
- An accumulation of dirt and other forms of deposits on the filter surface.
If you see any of these signs, it is high time that you clean your carbon filter.
Tools You’ll Need
Gather a soft brush or vacuum, mild detergent, a tub for soaking, and clean cloths or a fan for drying. These tools make the cleaning process efficient and thorough.
- Soft brush or vacuum cleaner with a brush on the end.
- Water that is warm and gentle soap solution (if necessary).
- Big tub or bucket which can be used for soaking.
- Dry clean clothes or a fan to dry the affected area.
Step to Clean Carbon Filter
Remove the filter, shake off debris, and brush or vacuum the surface. For washable filters, soak, rinse, and dry them completely before reinstalling.
- Take out the Carbon Filter from Your System
Slowly remove the carbon filter from the hydroponic system you are using. Do not scratch any part of the car while trying to remove it.
- Shake Off Loose Debris
Tap the filter lightly to remove the dirt that may be easily washed away. This step is useful to avoid too much dirt to be cleaned at once by the cleaning process.
- Brush or Vacuum the Filter Surface
Gently brush off any dust from the outer surface or vacuum clean it then turn it over. Be very careful but consistent in order not to compromise the filter material.
- Soak the Filter (If Washable)
Some carbon filters are reusable, they can be washed. If your filter is marked as such:
Take warm water and a mild detergent and pour the water into a tub or a bucket.
Immerse the filter and leave it to soften for about thirty to sixty minutes or so.
Stir the water slightly to facilitate their release from hair ‘traps’ as shown below.
- Rinse Thoroughly
After washing with soap, wash the filter with clean running water to wash off the soap and the debris that has softened.
- Dry Completely
After that, the filter should be dried on air until it is dry before reinstalling it. Any other method used to dry this filter should be done under the instruction of a professional. It is also possible to accelerate the formation of a dense layer by keeping the lamp at a fan or in an area with air circulation. Always make sure that the filter is as dry as possible, to avoid the formation of molds.
- Reinstall the Filter
After the filter is dry, one should replace it back on your hydroponic system where it should fit properly.
Tips for Maintaining Your Carbon Filter
Clean the filter every 1–2 months and use a pre-filter to catch large particles. Replace the filter when cleaning no longer restores its effectiveness.
- Regular Maintenance: Replace the filter daily, and clean it once a month if it is used often or if the air quality is poor.
- Pre-Filters: Pre-filter is used to capture large particles and thus relieve the carbon filter of the extra work it has to do.
- Avoid Overuse: Never overwork the filter’s cleaning cycles because this will not be good for the filter. Replace it when it is no longer efficient even after washing it severally.
The cleaning and reuse of the carbon filter is a cheaper method of maintaining the air quality in your hydroponic system. As you maintain the proper maintenance of your aquarium, you can also have better filtration for a longer period without developing harm to your aquatic plants. Just a note, though, a filter’s performance will degrade over time, and to get the best out of it, it should be replaced as needed.
