Really? So the kids in this area are stupid? They aren't smart? They haven't learned how covid spreads or how to keep people safe?  Interesting that so many stupid people live in Montgomery County but we are supposed to have one of the best school systems. Must not be so great if parents are all so stupid.[/quote]

A co2 monitor isn't going to help without many other layers in place.  This is theater for attention.[/quote]

Right. Other layers are in place. This is just another data point.

Jeez. People are just looking for things to complain about.  :roll: [/quote]

What are you talking about!   There is no mitigation this school year.  No masking, no distancing, no testing, no nothing.  Plan to get Covid multiple times.  What is the big deal, clearly you are ok with Covid?   [/quote]

Tests are available. Masks are available. Vaccines & boosters are available. HVAC systems have been upgraded/supplemented.

If you have concerns about a specific classroom there is no harm bringing in a CO2 monitor to verify adequate ventilation.

Available means nothing if not used.  Same thing with a co2 monitor if mcps or the monitoring parent does not pay for repairs.  [/quote]

If MCPS can't update/modify the HVAC system to increase ventilation, then the teacher can open the window. 
[/quote]

You’d need someone to properly study the airflow in the classroom to see if opening the windows will actually improve the air quality.[/quote]

Ventilation is the best way to improve air quality.

If the ventilation is poor (high co2 levels) then opening the windows will help until they upgrade/modify HVAC system.

[/quote]

It depends on a number of factors actually.  And it would be indefinite because it takes MCPS forever to upgrade.  You really want your kids sitting in extremely hot or cold classrooms for sone marginal improvement in ventilation? 90 degrees inside while wearing their KN95? [/quote]

If the co2 level is too high, then opening the windows absolutely will bring down the levels.

The weather isn’t that bad during the school year. My kid survived having the window open all last year. 
[/quote]

I ignore anyone who talks in such absolute terms because again, it depends on a number of factors. Buh bye.[/quote]

That’s just how ventilation works.  :roll: 
[/quote]

But will wi dies open on a 30 degree or 90 degree day meaningfully reduce covid? If not what’s  the point beyond driving more teachers away.[/quote]

Yes, open windows greatly improve ventilation - and meaningfully reduces transmission.

[i]“But when we opened windows, even just six inches, we consistently saw air-exchange rates above the “excellent” target of [u]five[/u] air changes per hour, with some rooms getting much more.”[/i]

[i]“With applications guaranteeing a complete replacement of the air in a classroom 2.4 times in an hour, infections were reduced by 40%. They were lowered by 66.8% with [u]four[/u] air replacements per hour and by 82.5% with [u]six[/u] air replacements, the study showed.”[/i]
[/quote]

What were the differences between east and west facing windows? Just curious.  We didn’t have AC as a kid and my east facing bedroom was so stuffy and stagnant at night while my sisters west facing room got a wonderful breeze.[/quote]

Too bad you didn’t have a co2 monitor to measure ventilation so you could compare. 
[/quote]

The question is why researchers conducting the study didn’t include this, no? My anecdotal measurements in my kid’s classroom would not answer that question.[/quote]
