This article considers the social, political and productive engagements with air as a foundational - but often invisible - consideration in scholarship. Drawing on ethnographic research in Angola, it develops Arundhati Roy's notion of "portals" as entry points into the reflection on and theorization of air. The paper argues that an "sanitized sensorium" of late globalized capitalism has shaped ethnographic work over the last two centuries, and in so doing has created an overwhelming reliance on visually informed insights that reveal only a small part of what can be made sense of. This is true for anthropology, as has been well documented, but it is equally true for the field of African studies. Here I suggest that in entering through alternative portals, including the olfactory, we might attend to the spaces between object and subject in which "the fullness of air" may yield valuable insmell - alongside insight.
