| Would other pants be on of I got the classroom a HEPA air purifier? |
More knowledge than you. It was the best way to provide adequate fresh air in a building with an old HVAC system -- it was just one of several layers our kid's school used to reduce transmission. I don't know if they plan to do it in the fall, but they certainly did last fall/winter/spring. It was a small price to pay to have kids in the classroom before vaccines. Most school HVAC systems are crap. If the air isn't being replaced 5-6x per hour then you have poor air quality in general, not even just covid concerns. If a school facilities crew can say that they have fresh air exchange, 5–6 air changes per hour, and CO2 <800 ppm then there would have been no need for teachers to monitor and take action. |

I am wondering if people who are upset about monitoring air quality are also upset about water quality testing or montoring for contamination in food ? Like.. guys we have the ability to do better. Indoor air quality is dismal, way worse than outdoor and schools are terrible offenders. Older buildings with outdated HVAC and no money for sexy stuff like utility upgrades - maybe for energy efficiency and that makes air quality worse!
I offered my child’s teacher and principal a co2 meter and was expressly requested not to send it. I respected the request though I wish I hadn’t. I monitor air quality in our home and at my office. My office is awesome, 500-600ppm, and I’d love the same reassurance for my kids school. |
Our ES has lead in the water and radon in the air. We have gotten letters alerting us for years about it. Shame on MCPS for not doing better |
There was no excuse for mcps not to use Covid money to do all the needed upgrades. Kids should not go to school in falling apart buildings. But a co2 monitor is theater and making you feel better when it’s not as helpful as other mitigation. |
+10000 I’m a teacher and really would love to start measuring this in my space. The ventilation is nonexistent. |
Nope. I see it as a situation in which many other people are going to have regrets that I won’t have. |
Even if there was masking and basic precautions with this new variant I would not send my kids in person when they like virtual and do well in it. And, we enjoy time as a family. I would far more regret sending my kids and one getting really sick when it was unavoidable. At least we have the stability of daily classes and not have to worry about kids missing a week or two of curriculum as they or a teacher is sick. |
DP. Can you show me some evidence that opening the windows will improve the air exchange in a statistically significant way- specifically in comparison to the "old" and "newer" systems. We had a parent at our school continually lobbying for open windows but one of the head facilities people in MCPS said it would work against the HVAC system. We are at a newer school. But it's hard to tell when people are lying and the parent advocate never shared anything beyond hand waving that open-windows-are-better so it was hard to know what to believe. |
I mean, that's great, but would you force your kids to stay in virtual if they didn't like it? You seem to imply that parents who send their kids to school are horrible, irresponsible parents but for you it seems to have been an easy choice because virtual worked well for your kids. That was not the case for many, many kids, particularly the younger ones. For ES kids, it's recommended they get no more than 2hrs screen time per day. I'm not going to just ignore that recommendation to appease my desire to never get sick. |
There are so many variables (types of hvac systems, room sizes, window placement, etc) that I’m not sure if a study like that exists. For that specific case, what were the measurements for that new HVAC system in the classrooms? Changes per hour? MERV rating? Unfortunately, even some newer systems may be inadequate in terms of ventilation (fresh air, not filtered/recirculated). This would be a good scenario for a CO2 monitor to see if the HVAC system was adequately pulling in fresh air.

I hate to tell you this but when we were in person before covid, kids got way more than two hours of screen time so you are kidding yourself to think in person doesn't have that. My kids gave me the passwords to all their accounts and some tracked how long they were in each day. My kids are flexible. We have always supplemented at home so it is pretty normal around here. I don't consider school screen time. |
I wish I could remember where I’d seen it, but I read a study where they found that open windows cause currents that in many cases actually drove the air in the room downward, or simply made it circulate around the room. It depends on room size, window placement, and both internal and external temperature and humidity. And in rooms where the HVAC was running, it threw the intended circulation patterns out of whack. So yeah, throwing windows open isn’t the panacea people think it is. |
I mean...good for you? Many (most?) kids despise virtual. There were a couple benefits for older kids that I'm sure are missed. Sleeping in and being able to easily cheat. |
Opening windows to dispute covid is actually huge. It is the difference from allowing it to linger and dispersing it. |
