Common Culture 4-inch carbon filter and inline fan combo for odor control
This combo pairs a 4" x 12" 200 CFM carbon filter with a 4" inline duct fan for filtration and ventilation in one setup. Activated granular carbon scrubs odors and airborne pollutants as air passes through the dense carbon bed. It is sized for smaller tents and rooms where tight odor control matters. The fan pulls warm, stale air through the filter and out of the space to hold temperature, humidity, and negative pressure.
4-inch carbon filter and inline duct fan for small grow rooms
The 4" inline duct fan moves about 165 CFM, matched to the compact filter so airflow stays steady without choking. Growers run the combo as primary exhaust, in a scrubber loop, or as a filtered intake to protect sensitive plants. It works with common 4" ducting and accessories for tents, closets, and small rooms. Keep the run short and sealed to hold full airflow through the carbon. One combo covers both odor control and active ventilation.
