Active Air Inline Carbon Filter, 6" x 24", 500 CFM

Filter Odor From Anywhere in the Line, Not Just the End

A standard end-of-line carbon filter only works where there's room to fit one — and in a tent, cabinet, or small grow space, that room is often the first thing to disappear.

The Active Air Inline Carbon Filter, 6" x 24", solves that by moving the filtration inside the duct itself. Air is filtered as it enters the unit's solid-exterior body and filtered again as it exits — two stages of odor control from a single component you can mount practically anywhere in the run.

Rated up to 500 CFM with a 6" flange on each end, it slots into an existing duct line in place of a plain coupler, turning unused duct space into active filtration.

Key Features & Benefits

• Mounts anywhere in the duct run — doesn't need to sit at the terminal end — install it wherever space allows along the line.
• Two-stage filtration — filters air on entry and again on exit through the same carbon bed, for added odor control from one part.
• Solid-exterior body design — filtration happens inside the unit rather than being pulled through an external mesh wrap.
• 1" carbon bed depth — a compact media depth chosen to filter effectively without adding bulk to the duct line.
• 6" flanges on each end — connects directly into standard ducting of that diameter with no separate adapter.
• Rated up to 500 CFM — sized to keep pace with a 6" x 24" exhaust setup without restricting airflow.

Who Should Use This Inline Carbon Filter

This filter is built for growers working in tents, cabinets, and other tight spaces where a standard end-mounted carbon filter simply won't fit — anyone who needs real odor control from a 6" x 24" line without sacrificing the room a separate filter would take up.

Fitting It Into a Tight-Space Setup

Because it mounts inline rather than at the end, this filter can take the place of a section of 6" ducting wherever your layout has the space — close to the fan, near the exhaust port, or anywhere in between. That flexibility is what makes it a practical fit for tents and cabinets where a traditional terminal-mounted filter would crowd out grow space.

Frequently Asked Questions

Where in my duct line should I install it?

Anywhere along the run where it physically fits — it doesn't need to sit at the end like a standard carbon filter, so place it wherever your layout has the room.

How is this different from a standard carbon filter?

A standard filter pulls air through an external mesh wrap at the end of the line; this one filters air through a solid-exterior body as it enters and again as it exits, all from a single inline part.

What size ducting does it fit?

It's built with 6" flanges on each end for direct connection to 6" x 24" ducting — confirm your duct diameter before ordering.

Will 500 CFM be enough for my space?

That depends on your room or tent volume and target air-exchange rate — match the filter and fan CFM ratings to your duct size and adjust from there.

Does it need a separate pre-filter?

No — its solid-exterior, two-stage design filters air directly through the carbon bed rather than through an external wrap that would need one.
