Description RHINO PRO CARBON FILTERS: 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. Unlike all other carbon filters with effective life spans of 9 to 18 months, our filters have always been known to have an out lasting performance for well over two years. FEATURES: • 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 • Sealed, boxed and labelled directly after manufacture for optimum lifespan, handling and presentation. • Large pores. Our carbon has bigger pores than carbon in other filters. These large pores allow the air to pass through the carbon more quickly than small pores, so the odour molecules in the air are trapped more quickly and efficiently. • Granulated not pelletised. Air moves through carbon granules but between carbon pellets. By forcing the air to move through the granules, the odour molecules are forced to interact with the carbon where they can be absorbed. • Effective at low contact time. Odours are trapped in just a 100ms of contact with the carbon in Rhino filters. That is literally in the blink of an eye.
