Featuring a patented refillable design with tool-free flanges, it delivers lab-tested odor removal equivalent to two standard filters. Constructed with durable dual-layer steel mesh and premium Australian virgin charcoal, it offers long-lasting, cost-effective, and sustainable odor control in high-humidity environments. ## 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.

Per il resto ok. ### ⭐⭐⭐⭐⭐ Works better with the Model B Charcoal Edition box filter frame from The 3DHandyman (Etsy) *by D***D on 22 October 2025* I got this refillable kit because other reviewers had said that the charcoal smells better. Plus you get a charcoal refill and scoop and funnel with it. I then mated this with the AC Infinity S8 Cloudline Duct Fan, and installed it inside one of the Model B Charcoal Edition HVAC filter frames, made by The 3DHandyman and available on Etsy. These are basically high end Corsi-Rosenthal HVAC filter frames, and I put four MERV13 20x30x1" Filtrete filters into this frame. I also taped down a 12x12x1" MERV13 filter on the top of this Model B, because this Charcoal canister does release a small amount of fine charcoal dust into the air. You can see the faint dark circle on the underside of this output filter, which is proof that this canister does release a small amount of charcoal dust. The charcoal dust may not be that important if you are using this in a grow house, but it is important to filter it out if you are using it inside a house and trying to completely remove particulate matter and smells in your indoor air. Reading all the reviews slamming this Carbon filter for getting clogged up with regular house dust and pet hair is ... I don't know, bewildering? Like duh, people, you need a PRE-FILTER around this charcoal canister so it doesn't get clogged up with the larger stuff floating in the air in your house. AC Infinity does sell a nice Pre-Filter cloth sleeve that fits very tightly around this canister that would work very well with catching the house dust and hair before it enters the canister, and this sleeve is a lot less expensive than getting one of these Model B box filter frames. However, the whole canister/duct fan breath and filter much better with the pleated MERV13 HVAC filters that the Model B frame surrounds it with. Plus you can also now easily filter out the fine charcoal dust that this canister puts out. ## Frequently Bought Together - AC Infinity 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 - AC Infinity CLOUDLINE PRO T4, Quiet 4” Inline Duct Fan with Temperature Humidity VPD Controller, WiFi Integrated App Control - Ventilation Exhaust Fan for Heating Cooling, Grow Tents, Hydroponics - AC Infinity Noise Reduction Clamp 4-Inch, Duct Coupler with Stainless Steel Clamps, Flexible Rubber Coupling for Inline Fans and Carbon Filters in Growing and HVAC --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/558507591-refillable-carbon-filter-kit-4-with-additional-refill-odor-removal](https://www.desertcart.co.uk/products/558507591-refillable-carbon-filter-kit-4-with-additional-refill-odor-removal) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-21*
