A wholly original replenishable carbon filter designed to permanently replace standard duct filters. This iF Award-winning patented structure can be regularly refilled to offer a cost-effective and sustainable solution for unwanted odors in your grow tent. The charcoal fan filter kit also includes 1+ refill making it as efficient as two standard inline carbon filters while proving more affordable. You can purchase additional refills at a fraction of the price of an entirely new carbon scrubber to further increase the value of this kit. Features an expanded chamber that enables you to achieve factory carbon compression and the same lab-tested levels of odor-blocking effectiveness as standard carbon filters. This also eliminates the need for you to actively compress your replacement charcoal and facilitates the refilling process. Reusable carbon filter features a patented design that eliminates the need to replace entire filters. Includes 1+ refill to match the filtration capacity of two standard same size carbon filters while costing less. Removable twist-off flanges support easy tool-free refilling using the included funnel and scoop. Larger chamber is lab-tested to block odors as effectively as standard filters with no compression required. Dual-layered steel mesh with protective coating withstands high humidity in grow tents through many grow cycles.
