Collection: Carbon Filters

A carbon filter sits between your grow space and extractor fan, pulling smelly air through activated carbon before it's vented outside. Match filter size to your fan's airflow (CFM/m³/hr) — an oversized fan reduces contact time and lets odour through. Shop CarboAir 50/60, Rhino Pro and Hobby filters, Phresh Filters, Mammoth's Carbon Filter, and AC Infinity's standard, XL and refillable options. Replace every 12–18 months.
