We did a market test comparing sales of bleached vs. non bleached AeroPress filters and the bleached ones far outsold the unbleached ones. Then we did a blind taste test comparison and coffee brewed using a bleached filter was overwhelmingly picked over coffee brewed using an unbleached filter. Together with the fact that gaseous chlorine is no longer used in the filter paper bleaching process these tests convinced us to continue using bleached filters.
