Abstract
A portable hood may include a base, a head, a column, and a roll filter unit. The roll filter unit may include a purification filter installed in the head and discharged to an outside of the head after moving past a suction inlet. Accordingly, one of purification filters, for example, an oil mist filter, may be provided as a roll filter, so cleanliness, maintenance, and replacement of the filter is easy.
