The quality of natural carbon sources varies from batch to batch. $95.61. 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 absorbtion) is sent back to the manufacturer. The result is the smallest, lightest and least restrictive carbon filter canister available. Phresh Intake & Inline carbon filter best for air filtration and ventilation systems setup. The advantages are easier installation, more airflow, and better air filtration with extended operating life.
