Are Vacuum Cleaners Bad for Your Health?
Australian Study Shows Most Vacuum Cleaners Release Dust,
Bacteria Back Into the Air
You vacuum your house religiously to get rid of all the
dust, dirt, and bacteria and make sure your indoor air is up to snuff. But new
research suggests that some vacuum cleaners may actually be making things
worse, not better.
Certain vacuum cleaners spit fine dust and bacteria back
into the air, where they can spread infections and trigger allergies. Australian
researchers tested 21 vacuum cleaners from 11 manufacturers, including two
commercial models. The vacuums were six months to 22 years old, and ranged from
less than $100 to almost $800. Brands included Dyson, Electrolux, Hoover,
iRobot, and Sanyo.
The researchers measured 62 different air emissions. All
released some bacteria, dust, and allergens back into the air. Newer and more
expensive vacuum cleaners generally caused less indoor air pollution than
older, cheaper models, the study showed.
Vacuums with high-efficiency particulate air (HEPA)
filters released only slightly lower levels of dust and bacteria than vacuums
that did not use these special filters. HEPA filters are supposed to remove
99.9% of the pollen, animal dander, and even bacteria from the air.
The new findings appear in Environmental Science &
Technology. “Both vacuum cleaning and the act of vacuuming can release and
re-suspend dust and allergens, leading to increased exposure,” write study
researchers from Queensland University of Technology in Brisbane, Australia.
So what now? If you are having breathing problems, ask a doctor
about it.
