The Rhino Pro Carbon Filter 100 mm x 300 mm fits 100mm or 4" ducting/fans. Airflow / Volume: 350 m3/hr.

These carbon filters are the daddy of all carbon filters, they use a thick layer of high grade carbon produced from coal (not coconut fibers) which results in very little ash & very little moisture. What this means for an indoor gardener is that they normally last over two years (compared to an average of one year for coconut carbon*)

About Rhino Pro Filters

The Rhino Pro Filter is constructed from Australian-mined RC412 carbon, the best in the world. The carbon is tightly packed and sealed into a high-efficiency airflow cylinder with a vortex cone in the base and a custom pore surface for maximum transference. The high-porosity carbon and lightweight aluminium make the Rhino filter smaller and easier to handle.

Replacement carbon sleeves are available to make them last even longer.

Features of Rhino Pro Filters:

• 50mm bed of RC412 activated carbon.
• 1.6mm aluminium tops and bases for reduced weight.
• Unique “Anti Air Bypass” system.
• 51% open area custom mesh for greater air flow.
• Machine packed carbon means more carbon and less movement.
• Coned internal base for optimum air flow

*Carbon filter life span depends on useage but most importantly moisture levels in the grow room, very high humidity will drastically reduce the lifespan of your filters.
