A large trial found no evidence that Hepa air filters reduce respiratory infections in care homes, challenging assumptions about their role in infection control.

@TheConversationUK@newsie.social Airborne particles tend to aggregate. They then settle or lodge safely in the upper reaches of the respiratory tract. I can see that if you remove the larger ones, the tiny particles have nothing to adsorb onto. Tiny particles can get deep into the lungs. It looks like a case where 'common sense' has a knowledge gap.
