Product Description
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.
Eco-Friendly Design
This first-of-its-kind filtration system removes the need to routinely purchase replacement filters and dispose of the old units. Each carbon filter features premium-grade Australian virgin charcoal and comes with 1+ refill. Its activated charcoal utilizes an enhanced surface area with a higher adsorption rate to help extend the time between refills. Further lengthen the charcoal bedding’s lifespan by reversing the filter’s easy-to-remove flanges. You can compost the used supply when replacing the charcoal to maximize its utility even further.
Highly Durable Build
The activated charcoal is safely locked within your odor filter by aluminum flanges and a secure rubber seal. The filter itself employs two layers of galvanized steel meshing with a sandblasted finish to protect the charcoal bedding. These multiple layers work together to effectively block odors in even the most humid environments by ensuring increased resistance to rust and corrosion.
Applications
This refillable carbon filter pairs with 4” inline duct fans and ducting to improve air quality in hydroponic grow rooms and grow tents. The kit includes a convenient funnel and scoop set and one charcoal refill for continuous odor scrubbing. Additional refills are available for purchase.
