1/ Just another reminder that his global pandemic is far from over. Reduce inhalation dose significantly to significantly reduce chance of infection. Fully vaccinate to reduce chance of severe outcome if infected.

2/ The fool proof way to reduce inhalation dose of virus-laden respiratory aerosol particles is to not put yourself in a position to be in the presence of those infected. This is not possible for most people, and so the next best approach (by far) is to ...

3/ Wear a high-quality mask (e.g., N95) in shared indoor spaces or in a home where someone is infected and isolating. After that, increase ventilation where you have control to do so or request/demand of others where possible and ...

4/ Improve filtration in HVAC systems (to MERV-13 if possible w/ continuous fan operation) and/or via standalone #HEPA air cleaners or #CorsiRosenthalBox es.

5/ In right-sized air spaces a good #CorsiRosenthalBox with 20" x 20" x (1 or 2") MERV-13 filters can easily achieve an increase of 5.5 to 7.5 equivalent ACH boost in a 700 to 800 square foot classroom (far greater than most HVAC systems are capable of achieving w/ outdoor air).

6/ If done right and safely, UV inactivation of viruses in aerosol particles, e.g., upper room UV, can also be highly effective.

7/ A right-sized CR Box in a classroom can reduce inhalation dose of virus-laden respiratory aerosol particles by 70 to 80%. Add high-quality mask (e.g., N95+) to achieve close to 99% (a 100 fold decrease in inhalation dose -- can be more depending on mask and fit).

8/ DRAMATIC reduction in chance of infection. A mask, 4 MERV-13 filters, a box fan & some duct tape. No rocket science, folks. Just a little common sense and will to reduce being infected, reduce infections of classmates, co-workers, friends and family, and spread in community.

9/ Just do it!

Doh! Not "his" global pandemic. "this" global pandemic. Twypo!!!!!
