Phresh Carbon Filters – RC-48 Activated Carbon Odour Control for Grow Rooms

Phresh Carbon Filters are a trusted choice for serious hobbyists and commercial growers seeking effective, long-lasting odour control and air purification. Using premium RC-48 Australian activated carbon in a machine-packed design, Phresh filters deliver superior performance at roughly half the weight of comparable filters — with a lifespan up to twice as long as many competitors.

The aluminium tops and bases improve airflow, while the 51% open mesh design keeps weight to a minimum — making Phresh filters ideal for overhead suspension in grow room setups. Available in a wide range of sizes to suit any extraction fan and grow space.

Please note: Due to transit damage risk, carbon filters larger than 200mm diameter are available for in-store collection only and cannot be shipped.
