Abstract
An air filtration unit for use in a work environment includes a housing disposed with an air filtration system and light source. The housing includes a handle and corner caps to prevent damage and provide stability. The air filtration system draws air into the housing, via a blower, through a first and second inlet gate, the air is at least partially filtered by a first and second filter assembly, which provide a two stage filtering, and then the at least partially filtered air is blown through an exhaust conduit back out into the work environment.
