Mountain Air 200/500 Carbon Filter — 740 m³/hr

Mountain Air 200/500 Carbon Filter — 740 m³/hr

The 200mm (8") version of Mountain Air's pro-grade filter range — same durable build, tested 37-month lifespan, and serious carbon density that's made the brand a reference in UK grow-room odour control. Paired with an 8" extraction fan, this handles flowering tents from 1.5m x 1.5m up through small commercial setups.

Why growers choose Mountain Air 200/500:

• 740 m³/hr airflow rating — sized for 1.5m tents and medium grow rooms with 8" extraction
• 37-month tested lifespan — 100% odour elimination across three full years of continuous flowering, in independent testing
• Deep activated carbon bed — more carbon by volume than budget filters, holds up to heavy flowering loads
• 200mm (8") flange — standard UK sizing, pairs directly with 8" fans and ducting
• Aluminium mesh construction — lighter than steel-body filters, easier to suspend in a tent frame
• Unique interior design — maximises carbon surface exposure to air, cleaner output than simpler filter designs

Who it's not for:

For smaller 1.2m tents, the 150mm filter is better matched — oversizing wastes carbon and pairing with an undersized fan chokes airflow. For larger 1.5m+ commercial rooms, step up to the 250mm or 315mm versions. Always match filter size to fan size.
