Filters and odour control products help manage smells in indoor growing spaces by filtering exhaust air and neutralising odours in the surrounding environment. The most common solution is a carbon filter paired with an inline fan, which scrubs odours as air is extracted from the grow area.
Alongside carbon filtration, odour neutralising gels, blocks, and sprays can help manage background odours in larger rooms, hallways, or intake areas. For best results, choose the correct filter size for your fan and maintain good airflow and negative pressure in the grow space.

Choosing the Right Carbon Filter
Carbon filters are one of the most important parts of an indoor ventilation setup. Matching the correct filter size to your inline fan (and your airflow rate) helps maintain negative pressure and consistent odour control.
