Abstract
To assist in maintaining the high degree of cleanliness required by Federal standards in industrial clean rooms, an upholstered seat is provided having a sealed filter unit through which air must flow when entering or exiting the seat structure. The filter unit is held in a sealed grommet installed in a hard base member on which is mounted a cushion. The base member and cushion are enclosed in an air-impermeable cover. The upholstered seat exceeds Federal standards in its ability to avoid contaminating clean rooms.
