Carbon Filter

Last updated: May 13, 2021

What Does Carbon Filter Mean?

Carbon filter refers to a method of filtration that uses activated carbon to filter out the impurities of water or air. Carbon filters use a process where the pollutants adhere to the carbon particles as the water or air passes through it.

Carbon filters are useful for purifying water and purifying the air of contaminants, but they are also exceptionally useful in removing the pungent aroma of cannabis plants in a growroom or greenhouse setting. They are often installed in an exhaust system.

Carbon filters do not alter the smell of the marijuana plants, but will successfully prevent the plant’s aroma from leaking out of the growroom. The exhaust fan vents the plant’s smell out of the growroom and across the carbon filter, which traps the smell so the plant’s telltale aroma is not released outside.

Carbon filters, also called carbon scrubbers, are especially beneficial at filtering out the smell of flowering cannabis plants grown in a growroom or grow tent. The filter pulls the smell of the plants from the air and neutralizes the odor via a functioning exhaust system. Ideally, a vacuum is created in the grow area to force the air through the carbon filter.

Whether it's for air or water purification, a carbon filter consists of a lightweight canister that is filled with charcoal or carbon that removes solids and toxins as the water or air moves through it. When used for air purification, they are simply installed up high in the room's ventilation system, or they can operate as stand-alone units if that is more convenient.

Carbon filters are handy for any grower because they remove chlorine, organic compounds, sediments, and even taste and odor from water, but do not remove the minerals that are valuable to plants. For this reason, carbon filters are also common for use in homes, aquariums, garden ponds, and wastewater treatment.

Carbon filtration is also commonly used to remove undesirable water additives or toxins from a hydroponic nutrient solution. Due to their shape, sometimes carbon filters are referred to as can filters, which also happens to be a brand name for a company who manufacturers such equipment.

Carbon filters are used in other types of filtration such as gas masks, some air conditioners, and in odor-proof baggage/luggage.

Carbon filters are highly efficient, durable, and function for a long time before they become 'full' and require replacing. The filters come in various sizes and shapes, including can (cylindrical) styles and flat styles, to fit whatever exhaust system the grower is utilizing.
