These White Elephant charcoal filters are highly absorbent and designed to fit with pipes that accommodate 9mm filters, helping reduce moisture and provide a drier smoking experience. At the ends of each filter are two flat ceramic caps that are highly heat resistant and feature ventilation holes that provide a natural draw and excellent air flow, especially when combined with their "less is more" approach, meaning 15% less filling per filter so as to avoid the restrictive draw sometimes found with traditional filters. Here presented in a pack of 40 filters.
