Abstract
This study investigated the emission characteristics of airborne particles and bacteria from six types of householdvacuum cleaners in the closed chamber. A test cleaner without HEPA filter was examined focusing on the firstone minute of initial operation, observing significant generation of airborne particles, and especially for particlesize of 0.5 to 2.5 μm, the generation rate increased up to 68.5 × 103 particles/min. Concentrations of airborneparticles and bacteria depends on the production year, the motor power, and the dust filter efficiency of the vacuumcleaner. The observed results should be taken into consideration in the design of the vacuum cleaner as well ashow they are operated in indoor environment.
