The message is correct. I would only specify secure firm fitting N95s and that influenza and RSV too are also or can be airborne.

Since 2020, our furnace has not combusted any fossil fuels. Just using the air flow feature to help filter the air with MERV13 filters, we keep 3 high CADR air cleaners running too. Covid has never spread in our home! 100% sure of that!

#Aranet PM, CO₂, radon monitored. Windows cracked = radon low. Closed = yikes 😬. Radon pump on hand, not installed. No rush. Heating bill? $75/yr (USDA wood permit). EPA-certified woodstove, dead Uinta NF trees put to use instead of rotting into CH₄ + CO₂.

Why let bad air build up in the first place? It should be a steady constant cleaning and filtering. It is not like trying to determine when your soapy kitchen sink dishwater needs changed. We keep our windows cracked open 2 cm and run air cleaners all day. HVAC is not on auto but runs continiously

"My Employee Was Upset I Told Him to Drive, Not Fly, on Business Travel."

Would you want to fly or drive for 5 h. You likely arrive at the same time. If I have to drive with colleagues, I just as well fly. I do enjoy driving solo, though I hate heavy traffic.

Combining genomic sequencing, CO₂ monitoring, and proximity sensors, most rigorous study yet!

This poster contains too much text to fit in the ALT text box, or to condense to a meaningful summary that would fit. The full text is accessible in the PDF linked directly from the post.

The 3rd annual Canadian Long COVID symposium wrapped up yesterday. It was a great meeting, and I got some nice news at the end!

I don't understand why anyone would think it wasn't airborne, it was clear on day 1.

Reasons for this lie could be...
Money 🤑 💰
You can't go spend money 🤑 if you are scared of the air 🤔
And work in the "mines" to make 💰💰💰 for the guys on top, "let's not spend money on protection use propaganda!"

24 students + 1 instructor in a 450 m³ room.
Pre-occupancy CO₂: 538 ppm
First hour average peak: 615 ppm
Second hour: 585 ppm

This was taken on 17 May 2008. My little girl is gone...now an adult, facing life with new challenges. Like the hour hand on a clock, you cannot see it move, but looking back, you realize it never stood still.

👩‍🏫 Fellow STEM Instructors:
Do you allow or require photo documentation in your labs?

How do you address safety, equity, and data permanence?

Would love to hear how others are blending visual tools with core scientific habits.
