Towel vs dryers study doesn't wash, says Dyson

摘要

Dyson has criticised a recent study that looked at the merits of paper towels against hand dryers, and specifically Dyson's Airblade, claiming the study is based on "poor science" and "poor methodology".rnThe study, headed by Keith Redway, at the Department of Biomedical Sciences, at the University of Westminster, and sponsored by the European Tissue Symposium (ETS), concluded that "the use of warm air dryers and the Dyson Airblade should be carefully considered in locations where hygiene is paramount" {Cleanroom Technology, March p5).rnToby Saville, senior scientist at Dyson, however, says the study, which has not been peer-reviewed, was "not good science" and was based on poorly generated data.rnThe study looked at how well the dryer compares with paper towels in drying hands and how many bacteria remain on the hands after drying, and whether contamination can travel in splashes from the dispensing devices.
