One ultrasonic and one impeller humidifier were charged with asbestos-contaminated waters (0.057-280.0 BAS/L) and individually operated in a room-sized chamber to evaluate the potential for portable home humidifiers to aerosolize suspended materials contained in the charging waters.
The resulting aerosol concentrations were highly correlated with both the charging water total solids concentrations and the humidifier emission rates.
TEM analysis showed the ultrasonic humidifier aerosol as primarily <6-mum-long, thin, individual fibers, which also served as an axis for a smaller dissolved minerals residual particle.
