so, i saw the article talking about the airblade spreading germs before, but upon re-examination it seems a bit weird. They dipped their hand into water with a harmless virus (as a stand in for a dangerous virus), but isn&#x27;t the whole point of washing your hands is to wash them with _clean_ water. Water coming out of a faucet is likely chlorinated and free from contamination. Right?<p>Just seems odd.<p>FTR, as cool as the airblades are, I have meat hooks for hands and have about .5 cm of clearance on either side when I use one, so I almost always bump into it. I&#x27;ll use paper towels if I can.<p>Either way, the Hygiene Hypothesis (<a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Hygiene_hypothesis" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Hygiene_hypothesis</a>) seems very reasonable to me, and while I haven&#x27;t studied it in depth, ancedotally it seems to ring true.
