Pro Grow Carbon Filter 200×800 mm

Description

The quality of natural carbon sources varies from batch to batch. Unlike our competitors, Phresh Filter only buy the premium 20% of any carbon produced. Our on site Carbon Analysis Laboratory allows us to independently batch test, de-dust and hand pick our carbon. We use the exact particle size required for the best air flow (Pro Grade 4/8). Any carbon that is too small, too dusty or does not meet our stringent air stream tests (minimum 20% butane absorption) is sent back to the manufacturer. The result is the smallest, lightest and least restrictive carbon filter canister available. The advantages are easier installation, more airflow, and better air filtration with extended operating life
