A'roFilter was a corporate entity engaged in mining activities, focusing its operations mainly on gas planets such as Bespin. It maintained connections with the Rebel Alliance, as Willrow Hood managed the covert provision of reduced-price tibanna from Bespin to Rebel operatives.
The A'roFilter concept was presented by Benjamin Christopher Norton Dawe within his What's The Story? submission regarding Willrow Hood. Initially, he named the organization AëroFilter, but this was later modified during the editing process.
