AC Infinity 6" Refillable Carbon Filter Kit

Eliminate single-use metal waste and lower ongoing operational costs with the AC Infinity 6" Refillable Carbon Filter. Winner of the prestigious iF Design Award, this patented air filtration system permanently replaces disposable duct filters with a fully replenish-able, eco-friendly design. Engineered for medium-sized greenhouses, grow tents, and indoor ventilation systems, the AC-RCF6 features an expanded internal chamber that locks charcoal into factory-grade compression without requiring manual packing during refills.

Out of the box, the kit includes enough Australian Virgin RC412 charcoal for two complete fill cycles (1 + refill included), providing the filtration capacity of two standard 6 inch filters at a fraction of the cost. Removable, twist-off aluminium flanges allow for quick, tool-free carbon changes using the included funnel and scoop set. Built with sandblasted, rust-resistant galvanised steel mesh and protective rubber seals, the filter housing easily withstands high humidity across multiple growing seasons.
