How Does Carbon Air Filtration Work?
Basically, carbon air filtration takes the air exiting the exhaust fans and makes it odorless. Air filtration can be necessary, and sometimes even essential when the environment is loaded with unpleasant odors.
Usually, activated carbon filters are used to sanitize an environment and reduce pungent odors from a grow room or grow tent with flowering marijuana plants. In detail, they are the best solution for filtering the air correctly and effectively, every single time.
To be precise, it is the activated carbon inside the filter that purifies the air exiting the air extractor. These activated carbon filters have internal chambers filled with carbon granules. As a result, they isolate/absorb odors and clean the air as it passes through. They can be used for both exhaust air to minimize odor, or as a way to purify the air that enters your grow tent.
Keeping the air clean and filtered will also go a long way in protecting your plants from pests. If you do notice an outbreak, neem oil is a great tool for prevention and mitigation.
What Do Carbon Filters For Grow Rooms Look Like?
Activated carbon filters have a cylindrical shape with one end closed and the other open. In the open end, there is a tapered section. On it, you attach the flexible hose with hose clamps or screw clips. Then, you connect the hose or duct to an air extractor or aspirator.
The filter also has metal walls filled with activated carbon. When the aspirator is active, the air passes through the filter walls. Here, the carbon granules neutralize all the odors, pollen, and dust.
What Makes Air Filtration With Carbon Filters Work?
Carbon filters for grow rooms offer a suitable contact time. That is, a period of time in which the air remains in contact with the coal granules. As you can imagine, the longer the contact time, the greater the elimination of bad smells.
Odor management is crucial during the flowering stage. For the correct efficiency of the filter, you should also do periodic maintenance. For example, by replacing the carbon granules inside the filter once exhausted.
How To Use A Carbon Filter For Your Grow Room or Tent
You can use an activated carbon filter effectively in one of two ways: extraction or recirculation.
Extraction means that the air passes through the filter and exits outside the cultivation area. This is the most common use for carbon filters in an indoor growing space.
Recirculation is about getting the cleaned air back into the cultivation space. In short, the filter continuously absorbs odors and expels them, allowing only purified air to enter your growing space.
How To Choose The Right Carbon Filter For Your Grow Room
The choice of an extractor and a filter with a compatible flow rate is of primary importance. Here is why it is such a crucial choice.
- A filter with a lower flow rate than that of the aspirator can cause an excessive air flow inside the filter. Thus, the contact time is consequently reduced. In other words, the filter becomes less efficient in eliminating odors.
- A lower air flow rate increases the noise level.
Broadly speaking, you will benefit from the best ratio between efficiency and noise. So, use a filter with a slightly higher flow rate than that of the aspirator. It shouldn’t matter which type of strain you have, growing sativa or indica strains both require proper filtration.
How To Choose The Right Carbon Filter For Your Grow Room
The life span of carbon filters for grow rooms depends on several factors. Usually, the filter’s life cycle is between 1,200 and 3,000 hours. In professional grow rooms, the filter will have an average duration of 3 cultivation cycles.
Once exhausted, you should replace the carbon granules and the internal filter as soon as possible. In fact, some models let you change the carbon granules while maintaining the supporting filter structure.
As Jorge Cervantes points out, carbon filters preserve the fragrance and overall quality of the cannabis buds. So, whether you use them in your grow or drying room, check their efficiency at least once a year.
