"Air filters can help, but healthcare and research centers may want to stick with towels."
We came across a fascinating article that you may want to read and remember. We've all come across the hot-air hand dryers in restrooms. We can figure out is probably minimizes germs and paper waste and clean-up. In fact, that may not be the case at all.
"Washing your grubby mitts is one of the all-time best ways to cut your chances of getting sick and spreading harmful germs to others. But using the hot-air dryers common in bathrooms can undo that handy hygienic work.
Hot-air dryers suck in bacteria and hardy bacterial spores loitering in the bathroom—perhaps launched into the air by whooshing toilet flushes—and fire them directly at your freshly cleaned hands, according to a study published in the April issue of Applied and Environmental Microbiology. The authors of the study, led by researchers at the University of Connecticut, found that adding HEPA filters to the dryers can reduce germ-spewing four-fold. However, the data hints that places like infectious disease research facilities and healthcare settings may just want to ditch the dryers and turn to trusty towels."
