Scientific Talking Points: Paper Towels vs. Jet Air Dryers
Learn why single-use paper towels are the most effective and most hygienic hand washing solution compared to jet air dryers[i].
- Paper towels reduce bacteria on hands by up to 77%.[ii]
- A recent study found people had 42% more bacteria on their fingers and 15% more on their palms after using a jet air dryer.[iii]
- The surfaces of jet air dryers have contamination levels 48 times higher than the average toilet seat.
- Fecal bacteria, E. coli and staph have all been found on jet air dryers.
- One study found jet air dryers disperse 1300 times more germ particles into the surrounding air than paper towels. Even after 15 minutes, there were still 100 times more particles in the air when using jet air dyers versus single-use paper towels.[iv]
- Most of the germ particles that jet air dryers blow into the surrounding air end up at approximately the height of a small child’s face.[v]
- The World Health Organization and Mayo Clinic support using paper towels over jet air dryers.[vi]
- Consumers prefer paper towels over jet air dryers. A recent observational study found 90% of people using restrooms prefer paper towels when given the choice between single-use paper towels and jet air dryers.[vii]
