With all-natural carbon sources, the quality can vary from batch to batch. Unlike other competitors. U-GO, use the precise particle size required for the best airflow (pro-grade 4/8). Any carbon that is too small, too dusty or does not meet their stringent air stream tests (minimum 20% butane absorption) gets rejected.

The advantages are more airflow, less dust and equal or better filtration with a longer expected operating life span. That’s the U-GO difference! The result is the thinnest, and least restrictive carbon filter canister available.
