An exhaust hood and related methods for exhausting fumes are disclosed. The exhaust hood comprises a housing forming a collection region having an entry portion and an upper portion disposed above the entry portion, an exhaust inlet coupled with the housing and configured to draw air from the entry and upper portions, and a supply assembly coupled with the housing and configured to output a flow of supply air. The supply assembly is configured to direct a first portion of the supply air across the collection region generally towards the exhaust inlet and direct a second portion of the supply air generally downward away from the collection area. The directed first portion of the supply air divides the collection region into the entry and upper portions. The portion of the supply air directed into at least the first portion or the second portion can be adjustable.
