SupremeAir Australian Carbon Filter - 12 x 39-in - 1700 CFM

Odor Control for Larger Exhaust Runs - 12 x 39 in

Exhaust air from an indoor cultivation space carries odor into the rest of the building. This carbon filter treats that air as it passes through a bed of activated granular carbon, so you can reduce odor without a complicated install. It is rated at 1700 CFM, which gives you a clear figure to match against your fan.

At 12 x 39 in, this is a mid-to-large canister suited to regular indoor growers running a ducted exhaust, and to commercial rooms that need a dependable filter on a single exhaust line. Check your fan and duct size before you order.

Key Features & Benefits

• 1700 CFM rating — lets you match the filter to your inline fan's airflow.
• Activated granular carbon — adsorbs odor molecules from air moving through the bed.
• Galvanized steel canister — protects the carbon and handles transport and handling.
• Built-in hanging brackets — help you suspend the filter in place.

Who Should Use SupremeAir Australian Carbon Filter 12 x 39 in

Choose this filter if you run a ducted exhaust in a grow tent or room and need a larger canister for odor control. It suits home gardeners with a large setup and licensed commercial growers who want a standard-size filter for an exhaust line.

Frequently Asked Questions

Q: What does CFM mean?
A: CFM stands for cubic feet per minute and measures how much air moves through the filter. This filter is rated at 1700 CFM. Pair it with a fan whose airflow suits that rating.

Q: Where do I place the filter?
A: Install it on the exhaust side of your ventilation, usually inside the space, so air passes through it before leaving. The built-in hanging brackets let you suspend it. Follow the installation guidance for your fan and ducting.

Q: How does a carbon filter reduce odor?
A: Activated carbon has a large internal surface area that traps odor molecules as air passes through. This lowers the odor in the exhaust air. Performance depends on airflow and carbon condition.

Q: Do carbon filters last forever?
A: No. The carbon gradually loses capacity as it adsorbs odor. Replace the filter when you notice odor returning.

Q: Is this sold as a single unit?
A: Yes. The listing is for one filter.
