Premium Australian Activated Carbon
Every AC Infinity carbon filter is packed with premium Australian RC412 activated charcoal, selected for its high microporosity and exceptional adsorption performance. With an iodine adsorption value (IAV) exceeding 1200, the carbon efficiently captures odours and airborne contaminants while maintaining excellent airflow.
The highly porous structure also contributes to a longer working lifespan compared to many standard activated carbon filters.
Maximum Airflow Performance
Unlike many traditional carbon filters that significantly restrict airflow, AC Infinity filters feature an open dual-sided galvanised steel mesh combined with a carefully engineered 38mm carbon bed. This provides an excellent balance between airflow and filtration, allowing inline fans to operate more efficiently while still delivering outstanding odour control.
Built to Last
Constructed using heavy-duty aluminium flanges and a powder-coated gunmetal finish, every filter is designed to withstand humid indoor growing environments. The corrosion-resistant construction ensures long-lasting durability, while the reversible flange design allows the filter to be rotated during its lifespan to encourage more even carbon usage.
Compatible With Most Inline Fans
The AC Infinity Duct Carbon Filter is designed to work with 4-inch, 6-inch, 8-inch, 10-inch and 12-inch inline duct fans, making it suitable for a wide variety of ventilation systems. It can be installed as either an intake or exhaust filter depending on your application.

Frequently Asked Questions
Which size carbon filter do I need?
Select the same duct size as your inline fan. For example, a 6-inch inline fan should be paired with a 6-inch carbon filter for optimal airflow and filtration performance.
How long do AC Infinity carbon filters last?
Filter lifespan varies depending on humidity, airflow and operating conditions, but the premium RC412 activated carbon and deep 38mm carbon bed are designed to provide long-lasting odour filtration under continuous use.
Can these filters be used for intake as well as exhaust?
Yes. The reversible flange design allows the filters to be installed in either intake or exhaust configurations depending on your ventilation setup.
Are replacement pre-filter sleeves available?
Yes. The included pre-filter sleeves are machine washable and help extend the life of the activated carbon by preventing dust and larger particles from reaching the carbon bed.

Whether you're ventilating a compact grow tent or a large indoor growing facility, the AC Infinity Duct Carbon Filter range delivers premium odour control, exceptional airflow and long-lasting performance. Available in sizes from 4" to 12", each filter combines Australian virgin activated charcoal, robust construction and intelligent design to provide one of the most effective carbon filtration solutions available.
