Carbon Filters by AC Infinity use Australian-sourced RC412 charcoal with a 1200+ IAV rating, packed into a 38mm carbon bed and housed in dual-sided galvanized steel mesh with reversible aluminum flanges. The reversible flange design effectively doubles useful filter life — flip the active side once odour breakthrough starts, and you get fresh charcoal contact for a second working cycle. Available in five sizes from 4 inch (210 CFM) up to 12 inch (1668 CFM) to match standard inline fan diameters and tent airflow requirements. Each unit ships with two pre-filter cloths, two hanging straps, and two rope clip hangers — a complete install kit out of the box.
Specifications
- Swap or wash your pre-filter cloth every 4–6 weeks during heavy use. A clogged pre-filter chokes airflow long before the carbon is spent.
- Run the inline fan 24/7 during flowering for continuous odour control. Carbon needs constant air contact to do its job.
- Flip the flange when odour breakthrough starts at the exhaust end. You'll get a second usable cycle out of the same filter before replacement.

Frequently Asked Questions
Which filter size do I need for my tent?
Match the filter to your inline fan diameter. Most 1.2m tents use a 6-inch fan and filter combo. Larger 1.5m tents typically use 8-inch. Commercial rooms use 10 or 12 inch. The filter's max CFM should meet or exceed the fan's rated airflow.
How long does a carbon filter last?
Typical lifespan is 12–18 months under continuous use, though high-humidity environments shorten this significantly. The reversible flange design effectively doubles useful life by exposing fresh charcoal once odour breakthrough starts on the original side.
What's the difference between RC412 and standard activated charcoal?
RC412 is a premium Australian virgin charcoal with a 1200+ IAV (iodine adsorption value) rating, which measures odour-adsorption capacity. Standard recycled charcoals typically rate 600–800 IAV. Higher IAV means more odour control per cubic metre of air passing through the filter.
Can I run the filter on the exhaust side instead of intake?
Yes — the reversible flange design supports both intake and exhaust mounting. Most tent setups place the filter on the intake side of the fan for negative-pressure operation, but exhaust placement works for positive-pressure rooms and sealed environments.
Do I need to use a pre-filter?
Yes — the included pre-filter cloths catch dust before it reaches the carbon bed. A clogged pre-filter restricts airflow and reduces overall filter lifespan. Wash or replace the pre-filter every 4–6 weeks during heavy use.
