Featuring a patented refillable design with tool-free twist-off flanges, it delivers lab-tested odor removal equal to two standard filters while cutting replacement costs and waste. Built with durable dual-layer galvanized steel and premium Australian virgin charcoal, it withstands high humidity and multiple grow cycles, making it the smart, sustainable choice for professional growers. ## Description Product DescriptionA 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 DesignThis 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 BuildThe 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. Review: great product - I have already saved so much money with refills. Review: Excellent product worth every penny - Excellent product with a really premium feel. Comes prefilled and with a resealable refill bag which I'd estimate will fill it twice. Particularly liked the fact the ends are interchangeable which helps lengthen the life of the filter considerably. Bought as a replacement to a vivosun filter which wasn't great at eliminating odor in addition to not being easily refillable due to having been rivetted together. In this day and age all these types of products should be refillable. I'm still on the original charcoal and have recently swapped the end caps round and zero odor after almost 8 months of continuous use. For comparison the vivosun lasted about 3 months and was never completely odor free. ## Technical Specifications | Specification | Value | |---------------|-------| | Brand | AC Infinity | | Compatible Devices | Inline Fan, Ducting | | Item Weight | 5.74 Kilograms | | Manufacturer | AC Infinity | | Material | Aluminum Alloy Steel | | UPC | 819137024168 | ## Product Details - **Brand:** AC Infinity - **Electric fan design:** Exhaust Fan - **Power Source:** Corded Electric - **Style:** Modern - **Product Dimensions:** 17.9D x 17.9W x 30H Centimeters - **Room Type:** Grow Tent - **Special Feature:** Refillable, Reusable - **Recommended Uses For Product:** Exhausting - **Mounting Type:** Duct Mount - **Controller Type:** Touchpad Control ## Images ![Refillable Carbon Filter Kit 4” with Additional Refill, Odor Removal Air Scrubber For 4" Inline Fan and Ducting, Reusable Charcoal Filter for Grow Tent Grow Room Hydroponics - Image 1](https://m.media-amazon.com/images/I/71u3DWkIWFL.jpg) ![Refillable Carbon Filter Kit 4” with Additional Refill, Odor Removal Air Scrubber For 4" Inline Fan and Ducting, Reusable Charcoal Filter for Grow Tent Grow Room Hydroponics - Image 2](https://m.media-amazon.com/images/I/71hFS5QacKL.jpg) ![Refillable Carbon Filter Kit 4” with Additional Refill, Odor Removal Air Scrubber For 4" Inline Fan and Ducting, Reusable Charcoal Filter for Grow Tent Grow Room Hydroponics - Image 3](https://m.media-amazon.com/images/I/61Wj-2Tx3vL.jpg) ![Refillable Carbon Filter Kit 4” with Additional Refill, Odor Removal Air Scrubber For 4" Inline Fan and Ducting, Reusable Charcoal Filter for Grow Tent Grow Room Hydroponics - Image 4](https://m.media-amazon.com/images/I/71D0cOybYrL.jpg) ![Refillable Carbon Filter Kit 4” with Additional Refill, Odor Removal Air Scrubber For 4" Inline Fan and Ducting, Reusable Charcoal Filter for Grow Tent Grow Room Hydroponics - Image 5](https://m.media-amazon.com/images/I/71yMH9fTX5L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ great product *by S***N on 16 September 2025* I have already saved so much money with refills. ### ⭐⭐⭐⭐⭐ Excellent product worth every penny *by B***I on 16 May 2026* Excellent product with a really premium feel.
