Description
A Deeper Carbon Bed for Rooms That Overwhelm a Standard Filter
The CarboAir 65 Carbon Filter sits between the CarboAir 60 and 75 in the Global Air Supplies (G.A.S.) range: a 65mm bed of virgin activated granular carbon in a single 250mm (10in) x 750mm body, rated at 2,650 m³/h. The extra depth gives the air longer contact with the carbon, which is what clears the heavier odour and VOC load of a busy grow room, while the tunnel-shaped design spreads air evenly across the mesh so your extractor fan is not fighting the filter. It is handmade in Europe and comes with a machine-washable pre-filter.
Key Benefits
- 65mm carbon bed – deeper than the CarboAir 50 and 60 for longer contact time and more odour capacity.
- 2,650 m³/h rating on a 250mm flange, leaving headroom for a powerful 10in fan.
- Low resistance – the tunnel-shaped design evens out airflow over the carbon and eases the load on the fan.
- Washable pre-filter included – catches dust before it can clog the carbon.
- Built for high-VOC rooms – part of the G.A.S. professional range made for heavier odour loads.
- Handmade in Europe, with an 18-month warranty.
Odour Breaking Through a Thin Carbon Bed
A packed room running warm gives off more volatile organic compounds than a shallow carbon bed can hold. Air passes through too quickly, contact time falls and smell escapes even with the fan running hard. The usual answer, a dense filter packed with fine carbon, strangles airflow instead, so heat and humidity build up, air stagnates around the canopy and the risk of mould rises. A deeper bed of coarse, high-grade carbon deals with both: more carbon in the air path for better odour removal, with enough open area to keep extraction strong and the climate stable.
How to Use
- Pair it with a 10in (250mm) fan whose working airflow sits at or below the filter's 2,650 m³/h rating.
- Fit the pre-filter over the mesh body before hanging.
- Hang it high in the room from the fitted lugs, on rope ratchets or chains rated well above its weight.
- Connect the flange to the fan's intake so air is drawn through the carbon, and seal the joint with a fast clamp.
- Wash the pre-filter when it greys over and refit it once dry; keep the carbon itself dry.

Frequently Asked Questions
How does the CarboAir 65 differ from the CarboAir 60 and 75?
They are built the same way; the difference is carbon depth. The 60 has a 60mm bed in several sizes, the 65 a 65mm bed in one 250mm x 750mm size, and the 75 a 75mm bed on 315mm and 355mm flanges for the largest rooms.
Which fan should I pair it with?
A 10in (250mm) inline fan whose real-world airflow is at or below 2,650 m³/h. G.A.S. pairs its professional CarboAir filters with the Revolution Silenced V2 fans for a quiet, odour-free extraction system.
Is the pre-filter replaceable?
Yes. It is machine washable for routine cleaning, and G.A.S. makes a replacement pre-filter in the matching 250 x 750 size.
