Fresh air contains the "open air factor", thought to be ozone or ozonated hydrocarbons, that kills microorganisms, including viruses.
The factor is potent: single digit percent survival of some viruses when exposed to open air for 1 hour.

The open air factor operates both day and night, and the factor is rapidly deactivated when enclosed, presumably by reacting with enclosure surfaces.
This means that fresh air in your house can be an effective germicidal.

The open air factor may be the basis of the known effectiveness of open air in treating influenza.
Also of the known effectiveness of better ventilation in decreasing spread of infections..

In 1918, open-air treatment was used in the influenza pandemic, and many doctors were convinced of its effectiveness.

The value of fresh air for health is proverbial, so perhaps in the old days they knew something that we've forgotten.
"in 1918 a British soldier, Patrick Collins, reached a similar conclusion. When Collins developed the first signs of influenza, he dragged himself and his tent up a hill away from his regiment."
"There he sweated, shivered, and was delirious for several days, sustained only by his rum ration. He was one of the few survivors of his regiment."
