Phresh Intake Filter 150x300 mm is an intake-side carbon felt drum by Phresh Filters designed to remove incoming contaminants before they reach the grow space. The 150 mm (6-inch) diameter unit is 300 mm long and mounts directly to matching ducting. The APEX carbon-impregnated felt media and perforated mesh body provide low pressure drop, dispersing intake air evenly. Phresh specifies capture of 98.7% of airborne pathogens and contaminants for at least three months, and 99.9% of pollen, dust and insects for up to 12 months when used as intended. The 150×300 mm variant is rated up to 765 m³/h, aligning with typical 6-inch intake fans. Use on the intake line to protect downstream carbon filters and maintain clean, balanced airflow.
