Researcher: Older, cheaper vacuums spread germs

January 6, 2012

BRISBANE, Australia, Jan. 5 (UPI) -- Some vacuum cleaners add to indoor air pollution by releasing bacteria and dust that can spread infections and trigger allergies, researchers in Australia say.

Lidia Morawska, a professor at Queensland University of Technology in Brisbane, and colleagues said previous research showed vacuum cleaners can increase levels of very small dust particles and bacteria in indoor spaces, where people spend about 90 percent of their time.
