Beschreibung
The AC Infinity Refillable Carbon Filter Kit is a reusable alternative to standard carbon filters. Instead of throwing away the whole unit once the charcoal is spent, simply twist off the flanges, tip out the old charcoal, and refill with fresh activated carbon using the included funnel and scoop. One kit, refilled again and again, works out far cheaper over time than replacing disposable filters.
Pairs with an inline duct fan to scrub odours from grow rooms, grow tents, and hydroponic spaces. Dual-layered, rust-resistant steel mesh holds the charcoal bedding securely, even in high-humidity environments, cycle after cycle.
Ready for Its First Refill? Each kit ships with one charcoal fill included. When it's spent, top back up with the Activated Carbon Refill - 8lb Bag (AC-CAR8), good for 2+ refills on the 4" filter or 1+ refill on the 6".

- Lab-tested to block odours as effectively as standard filters, no charcoal compression required

- How often should I refill it? This depends on airflow, humidity, and grow cycle length, but the RC412 charcoal's high IAV rating means it lasts noticeably longer than standard filter charcoal.
- Can I use it outside of grow tents? Yes. It also suits general air filtration projects and can improve air quality around aquariums, fish tanks, and ponds.
- Does refilling require compression? No, the charcoal is lab-tested to perform without active compression during refilling.
