Particle emissions from vacuum cleaners

摘要

Vacuuming is often promoted as a means of reducing indoor concentrations of settled particles and dust, thus maintaining a clean indoor environment. Several studies have shown that the act of vacuuming can be a significant source of indoor particle exposures itself due to re-suspension of settled particles. Far fewer studies have examined the particle emission characteristics of vacuum cleaners, which contain motors capable of producing ultrafine particles. To address this gap in knowledge, we investigated the particle emission characteristics of a range of vacuum cleaners.
