A carbon filter (also called a charcoal filter or carbon scrubber) is an odour control device used in indoor growing spaces. Air is drawn through a cylinder packed with activated carbon, which adsorbs volatile organic compounds (VOCs) β including plant odours β before the air is exhausted from the grow space.
Key Facts
- Activated carbon adsorbs VOCs and plant odours through a chemical bonding process
- Connected between the grow space and the exhaust fan via ducting
- Matched to the inline fan by CFM (cubic feet per minute) rating for effective scrubbing
- Lifespan: 12β24 months depending on humidity and usage intensity
- High humidity reduces effectiveness β keep relative humidity below 70% in the grow space
- Available in various sizes to match tent volume and fan capacity
