To help reach those pesky, hidden high spots, vacuum manufacturers offer a list of specialized attachments, like extension wands and paddle tools. A few manufacturers have also introduced new equipment that is specifically designed for these hard-to-reach areas.
Richard J. Shaughnessy, Ph.D., program director of Indoor Air Research at the University of Tulsa, in Oklahoma, says it's not just about the dust that's hiding in those high spaces. "Any time you have any particulate matter that accumulates on flooring, people are going to walk on that and it will re-suspend back into the air."
Where does all that dust go? Up.
"The re-suspended dust gets picked up by air currents and ventilation, and often it settles up high on bookshelves, light ballasts and things closer to the ceiling," says Shaughnessy. |
