AC Infinity Australian Charcoal Carbon Filter XL - 4 INCH (300 CFM)

A high-airflow inline duct filter designed to eliminate odors and chemicals, most used in hydroponics builds, grow rooms, kitchens, smoking areas, and other ventilation projects. Features premium-grade Australian Virgin charcoal bed made up of activated carbon. Its extra-large size enables a greater capacity of the activated carbon to extend its lifespan while maximizing airflow passthrough. The filter can be used in conjunction with an inline duct fan for use in intake and exhaust configurations. Heavy-duty construction contains aluminum flanges and dual-sided stainless-steel mesh. The flanges can also be reversed to further prolong the life of the filter. Includes two machine washable pre-filter cloths to prevent carbon residue and two rope clip hangers to suspend the extra-large carbon filter above ground.
