Here's my number: 87.5%
That's how much of a reduction in COVID spread can be achieved through:
- 6 air changes per hour (ACH) of ventilation +
- Upper room UVGI +
- #CorsiRosenthalBox .
No mandates required.
Where did that number come from?

75% reduction in transmission of measles from upper room UVGI. 25% remains.

50% reduction in transmission of measles from ventilation/filtration. 50% of these remain.

25% * 50% of cases remaining = 12.5% total remaining = 87.5 % reduction.
These methods work better together - better air circulation makes upper room UVGI more effective. CR Box addition mixes air even more and removes all PM2.5, not just virus laden aerosols.

87.5% reduction in COVID transmission from ventilation, filtration and upper room UVGI?!
Am I too optimistic?
Too much faith in engineering measures?
Fine. Run some RCTs and prove me wrong.
