Abstract

A compact "cylindrical-sandwich" filter was designed specifically for a personal air ventilator (PAV). It was a three-layer ?sandwich? with both fibrous particle filtration media and sorbent media for gaseous pollutant removal. The filter was designed to have high capacity for volatile organic compounds (VOCs) as well as low pressure drop. The performance of the filter incorporated in the PAV device was tested in a full scale chamber with a thermal manikin simulating a human body. Toluene and formaldehyde were selected as target pollutants. Results indicated that the effectiveness of the personal ventilator critically depended on the diffuser outlet design, distance to the breathing zone and the direction of the projection. Challenges of obtaining significant reduction of occupant exposure through the use of such a PAV device are also discussed.
