Yesterday, I dropped off three #CorsiRosenthalBoxes at the office of Gwaandak Theatre. Kudos to the #Yukon’s only Indigenous professional theatre company for caring about cleaning the air and keeping staff and talent safe in an ongoing pandemic ❤️

Someone asked what I’ve been doing these last few years. As usual, I answered vaguely, learning the hard way from past dismissive responses when I talk about my #Covid19 investigative work.
But it did motivate me to finally organize all my paperwork (which represents fraction of my computer files):

Very squirmy and very fast on their little webbed feet. The phrase herding cats comes to mind. Spouse and I are never without our N95s outside of our home. Plus we have three #corsirosenthalboxes in our household and a portable HEPA for dentist/doctor appointments. #itsairborne #canada #cdnpoli

And I still highly recommend #CorsiRosenthalBoxes, make, & give them away. And will do this indefinitely -

Spot-on — keep in, contrary to the silence from PH officials, "during covid" is right now... yes, still. One of the most important things we can do is outlive the fascists. So, #WearARespirator, because #CovidIsAirborne, and use other tools like #CorsiRosenthalBoxes to provide #VirusFreeAir.

Btw, whatever happened to the Swiss cheese doctrine? I'd give odds that deploying #FarUVC along hallways and in the gym(s) would render classroom and office-deployed #CorsiRosenthalBoxes far more effective than this study suggests...

First, make respirators the standard — baggy-blues only block ballistic droplets. Make them mandatory in healthcare settings... where sick households congregate. Beef up ventilation, and use #CorsiRosenthalBoxes and/or #FarUVC where patients have to unmask.
Haven't been sick since 2019.

We have masks available but since we weren't home when the renos took place we were being cautious. We opened the windows and plugged in our three #CorsiRosenthalBoxes and wore respirator masks while we unloaded our trailer and organised the indoors of the house.

Indeed, I am curious: why did the who never undertake even the most rudimentary public education campaign to tell people that #CovidIsAirborne simple, low-cost tools, like #CorsiRosenthalBoxes and #WearARespirator, enable them to breathe #VirusFreeAir?

Opening the 'economy' came at an enormous cost to human lives and the yet economy is still suffering. It could all be mitigated by using HEPA filters or the lower cost #CorsiRosenthalboxes in all indoor spaces. We'd see a huge reduction in employee absences, disability and premature death. 2/2

From the CDC:
Choosing to wear a mask during respiratory illness season can provide an extra layer of protection for yourself and others.
- Masks can help reduce the spread of germs when worn by someone who is sick.
- Masks protect people who wear one from inhaling germs in the air.
