Premium Grade Australian Carbon

Each carbon filter features a premium-grade Australian Virgin charcoal bed rated at 1200+ IAV. It achieves a 38mm charcoal bed thickness and wider mesh openings thanks to a higher microporosity and surface area rating. This combination not only enables a higher adsorption rate without restricting free airflow, but it also allows the carbon filter to last up to 33% longer.
