Activated Carbon Pellets (Acid-Free) – 4 mm Refill Media for BentoBox v2.0 & Enclosure Air Filters

Premium 4 mm acid-free activated carbon pellets designed for air and water purification — ideal for refilling BentoBox v2.0 carbon filters and other 3D printer air-scrubbing systems. Keep your enclosure air clean and odour-free with high-grade, long-lasting carbon media.

These 4 mm acid-free activated carbon pellets are the same premium grade we use in our own BentoBox v2.0 carbon filter kits. Sourced from a trusted Australian supplier, this carbon media effectively captures volatile organic compounds (VOCs) and printing odours released during 3D printing with materials like ABS, ASA, Nylon, and more.
