The indoor use of HEPA filtered air has been demonstrated to be ineffective. In one case (Korea?) in 2 hours, a diner infected 9 other people who were sitting around his table or between him and the air filter intake. At least other diners outside the air flow were protected but still it's not enough.
That's still better than the team sitting in an 'agile' office space where everyone sits within 6 feet of 8 other workers. One person infected 52 of 80 coworkers in 8 hours. And another 11 people on the floor.
An interesting observation from a friend in the building cleaning business. They are being told when we go back "we're going to have alternate desks rotate which week they are in the office. If older workers want to quit or die that's OK with us, as managers we have doors on our offices.
Slight fallacy about just the old people being taken. The +70 crowd tend to die within days of respiratory distress. But the 30 to 60 year olds die too. Just they get sick from a couple of weeks with manageable symptoms... then suddenly crash due to their autoimmune system suddenly attacking their whole body.
I'm still social distancing on the Connecticut River.
