activated carbon filters
dubi - a passion
We love to roll with activated carbon filters!
For a long time no solution could satisfy our demand for highest quality. That is why, after four years of R&D, we have managed to build a filter with minimal drag, excellent taste and no clogging issues.
A filter that was developed for rolling!
100% more and sustained airflow than any other filter!
Independently conducted studies with the most commonly available activated carbon filters show clearly, that dubi is obviously the best choice when it comes to the most important filter criterias, such as airflow, drag and taste. Learn more at porchdavis.
