Air Box 4+ Stealth Edition Carbon Filter - 12-in Flanges - 3500 CFM

Replaceable Carbon Odor Control for Large Rooms - 3500 CFM

Strong odor from a large cultivation room is hard to contain with undersized filters. This carbon filter uses virgin coconut charcoal in replaceable high-flow filters, and it is rated for a flow rate of 3500 CFM. The distributor describes the housing as airtight, so air passes through the media instead of around it.

This is a large unit, sold each. It suits commercial rooms and serious home setups that run big 12-in ducted fans, rather than small tents or trial spaces.

Key Features & Benefits

• 3500 CFM flow rate — handles the airflow of large rooms.

Who Should Use Air Box 4+ Stealth Edition

Commercial growers and home growers with large indoor rooms who need dependable odor control on a 12-in duct system. It is a poor fit for small spaces with low airflow.

A: CFM is cubic feet per minute, the volume of air that moves through the filter each minute. Match it to the airflow of your fan and room.

A: Yes, the filters are replaceable. You can renew the media without buying a new housing.

Q: Is it for commercial or home use?
A: The distributor describes it as suitable for both. Its size and airflow make it best for large rooms.

A: It has 12-in flanges, so it connects to 12-in ducting. Check your fan and duct sizes before ordering.
