Minimal at best. An absolute waste of money at worst: engineers and mech techs.

It’s depressing that we are just writing about this 2 years into the pandemic.

Total bs…many (if classroom lucky enough to have one) are too small to be effective

We had 2 years to prepare for this and we sat on our thumbs hoping that needles would be our saviour. While they have helped they weren't the answer and now we are paying the price! Our government at all levels is a massive failure and we need to hold their feet to the fire!

So we're just straight up ignoring science and being open about it. Cool. What they mean to say is that there are no studies to SUPPORT them as a means to protect against covid, while they fail to mention that there's evidence that they DON'T. But keep making ppl afraid, it's coo

I know we all probably might have heard about Bitcoin but don't know how it works, I tried it in a week ago by a man who recommended me to Derrick_Jones39 on Twitter he guides me through and i made a return of $10500 after a week of trading, connect with him

Or you could build a Corsi Rosenthal box or two for each classroom. Less than $100 each in materials and pretty much equivalent to the fancy HEPA filters. corsirosenthalbox

I am from the HVAC industry, and concur. Filtration via HEPA filters or even Merv-13 and higher filtration will remove the majority of particles, germs in the air. It is effective when there is a minimum amount of fresh air that can be introduced. Fresh air is ideal though.

The negative side of this is the need for this equipment to be very well and frequently cared for or it can become toxic to the classroom environment.

The perspective of the experienced ventilation engineer is worth gold.

Mask them, vax them, separate them from each other, make them do everything online and shame them into compliance. That's funny how air filtration was never considered before all of these other ideas.

Sauf une fois au Québec! polqc
