Description
Premium Activated Carbon Air Filter for Grow Tents, Grow Rooms & Ventilation Systems
The AC Infinity Duct Carbon Filter is a high-performance activated carbon air filter designed to capture unwanted odours and airborne chemicals while maintaining excellent airflow through indoor ventilation systems.
Built around a 38mm thick bed of premium Australian Virgin RC412 activated charcoal rated at 1200+ IAV, the filter provides a large adsorption surface for effective odour control. Its high-microporosity carbon structure is engineered to capture odour molecules without unnecessarily restricting airflow, making it an ideal companion for AC Infinity CLOUDLINE and other compatible inline extraction fans.
Heavy-duty aluminium flanges, galvanized steel mesh and a corrosion-resistant gunmetal finish provide durability in humid grow-room environments, while reversible flanges allow more of the carbon bed to be utilised over the filter's service life.

Premium Australian Virgin Activated Carbon
The performance of a carbon filter is heavily dependent on the quality and quantity of its activated charcoal.
AC Infinity uses Australian Virgin RC412 activated carbon with a 1200+ IAV rating. Its high microporosity provides a substantial internal surface area capable of adsorbing odour molecules as contaminated air passes through the filter.
The filter uses a 38mm carbon bed, balancing high adsorption capacity with efficient airflow. AC Infinity states this carbon and airflow design can provide up to 33% longer service life compared with conventional inline filters.
Powerful Grow Room Odour Control
When connected to a correctly sized inline fan, air is drawn through the activated carbon bed before being exhausted from the growing environment.
Odour molecules become adsorbed onto the enormous internal surface area of the activated charcoal, helping prevent unwanted smells from escaping through the ventilation system.
This makes the AC Infinity Carbon Filter ideal for:
- Indoor grow tents
- Hydroponic grow rooms
- Indoor gardens
- Extraction systems
- Controlled-environment agriculture
- Ventilation systems
- Smoking areas
- Kitchens
- Workshops
- Other applications requiring odour filtration
High-Airflow Design
Effective filtration shouldn't come at the expense of ventilation.
AC Infinity combines a high-microporosity carbon bed with wide mesh openings to allow strong air passage while maintaining effective odour adsorption.
This helps reduce unnecessary CFM losses when the filter is paired with an appropriately sized inline fan, allowing the ventilation system to continue removing heat and stale air while controlling odours.
Heavy-Duty Construction
The AC Infinity Carbon Filter is designed for demanding indoor environments where elevated humidity can quickly affect lower-quality filtration equipment.
Construction features include:
- Heavy-duty aluminium flanges
- Dual-sided galvanized steel mesh
- Corrosion-resistant construction
- Durable gunmetal finish
- High-airflow mesh design
- Thick activated charcoal bed
- Reversible flange system
The robust housing helps protect the carbon bed while maintaining unrestricted airflow through the filter.
Reversible Flanges for Extended Filter Life
A standout feature of the standard AC Infinity Carbon Filter range is its reversible flange design.
Over time, the section of carbon closest to the incoming contaminated air can become exhausted before other areas of the carbon bed.
Reversing the flanges allows the airflow direction through the filter to be changed, helping growers make more effective use of the remaining activated carbon and potentially extending the filter's useful service life.
Machine-Washable Pre-Filters
The filter includes two machine-washable pre-filter cloths.
The pre-filter wraps around the outside of the carbon filter and helps capture larger airborne particles before they reach the activated charcoal.
This helps protect the carbon bed from:
- Dust
- Hair
- Fibres
- Larger airborne particles
- General grow-room debris
Regularly cleaning the pre-filter helps maintain airflow and protects the activated carbon from unnecessary contamination.
Intake or Exhaust Configuration
The AC Infinity Carbon Filter can be incorporated into both intake and exhaust filtration configurations.
A common grow-room configuration is:
Carbon Filter → Inline Fan → Ducting → Exhaust
This arrangement pulls odorous air through the activated carbon before exhausting filtered air from the grow space.
Depending on the ventilation design, the filter can also be positioned elsewhere within the duct system.
Available Sizes
The standard AC Infinity Australian Charcoal Carbon Filter range includes multiple duct diameters to suit different ventilation requirements.
| Duct Size | Filter Length | Maximum Airflow |
|---|---|---|
| 4 Inch | 12" / approx. 30cm | 210 CFM |
| 6 Inch | Standard Size | Match to Compatible System |
| 8 Inch | 20" / approx. 46cm | 770 CFM |
| 10 Inch | 24" / approx. 60cm | 1249 CFM |
| 12 Inch | 28" / approx. 70cm | 1668 CFM |
AC Infinity also produces Extra Long models in selected sizes for growers requiring greater carbon capacity and extended filtration performance.
Choosing the Correct Carbon Filter Size
For best performance, match the carbon filter's duct diameter and airflow capacity to your inline extraction fan.
For example:
- 4" inline fan → 4" carbon filter
- 6" inline fan → 6" carbon filter
- 8" inline fan → 8" carbon filter
- 10" inline fan → 10" carbon filter
- 12" inline fan → 12" carbon filter
The complete ventilation system should also account for grow-space volume, required air exchanges, duct length, bends, lighting heat load and other airflow restrictions.

Why Choose the AC Infinity Carbon Filter?
A grow-room carbon filter needs to achieve two things effectively: capture odours and allow sufficient airflow.
AC Infinity's filter combines a substantial 38mm carbon bed with premium 1200+ IAV Australian Virgin RC412 charcoal, creating a high-surface-area filtration medium designed for strong adsorption without excessive airflow restriction.
Add the reversible flanges, washable pre-filters, heavy-duty metal construction and broad range of sizes, and the result is a professional filtration solution suitable for everything from compact grow tents to large indoor ventilation systems.
For growers already using an AC Infinity CLOUDLINE inline fan, the matching carbon filter also provides a straightforward way to build a complete extraction and odour-management system.
FAQs
What type of carbon does the AC Infinity Carbon Filter use?
It uses premium Australian Virgin RC412 activated charcoal rated at 1200+ IAV.
How thick is the carbon bed?
The standard filters use a 38mm thick activated charcoal bed.
What does the carbon filter remove?
It is designed to adsorb unwanted odours and airborne chemicals as air passes through the activated charcoal.
Does it reduce airflow?
All filtration creates some resistance, but the AC Infinity filter is specifically engineered with high-microporosity carbon and wide mesh openings to maximise airflow passthrough while maintaining effective adsorption.
Can I use it with an AC Infinity CLOUDLINE fan?
Yes. The filters are designed to pair with compatible inline duct fans, including matching AC Infinity CLOUDLINE models.
Can it be used as an intake filter?
Yes. It can be incorporated into either intake or exhaust configurations, depending on the ventilation system.
What is the pre-filter for?
The cloth pre-filter captures larger particles such as dust, hair and fibres before they reach the activated carbon.
Can the pre-filter be washed?
Yes. The supplied pre-filter cloths are machine washable.
How do the reversible flanges help?
Reversing the flanges allows growers to change which portion of the carbon bed receives incoming contaminated air, helping maximise utilisation of the activated charcoal.
How long does an AC Infinity Carbon Filter last?
Filter life depends heavily on humidity, odour concentration, airflow, operating hours and pre-filter maintenance. Replace the carbon filter when odours begin passing through despite correct airflow and installation.
Which size should I choose?
Match the filter's duct diameter to your ventilation system and ensure its airflow capacity is suitable for your inline fan and grow-space requirements.
