Premium Grade Carbon

Each carbon filter features premium-grade Australian Virgin charcoal bed rated at 1200+ IAV. Due to a higher microporosity and surface area rating, we were able to thicken the charcoal bed to 38mm and increase the mesh open area to 55%. This combination not only enables a higher absorption rate without restricting free airflow, it allows the carbon filter to last up to 33% longer.
