Activated carbon filters are a widely used technology to reduce odors and control emissions from greenhouses and other growing applications. The ambient air is circulated through the activated carbon filter and returned to the greenhouse (scrubbing) or discharged outside (filtering). Understanding the basic guidelines of how activated carbon filters work will help the individual grower use the technology with greater reliability and lower overall cost.
