Can INLINE 425 Carbon Filter 125mm (5") NOT CAN-LITE

CAN Inline Carbon Filters are made from Can’s lightweight, high grade carbon and are designed to fit directly into inline in runs of ducting, rather than at the point of extraction. They use the lightweight version of CAN Filter carbon that will last for around 18 months (CAN have a lightweight type and a pelletized type – the pelletized type lasts longer but is significantly heavier). Some growers use them as a belt and braces secondary filter, but as long as you match them with the correct fan and airflow, they are fine to use as a primary filter. As the carbon used is Can’s lightweight type, they will not affect the airflow too much.
