Our indoor air is contaminated. It sickens us unnecessarily. It's easy to make significant improvements. Read up and get started! 🏳️🌈 🏳️⚧️ Uncredentialed.
With portable air cleaners or one or more #CorsiRosenthalBox'es, we can make classrooms at least a bit safer. You can make a big difference with just 400 USD (depends on salestax). With 21 students, this gives more than 16 liters of cleaned air per student per second.
1/@nilikm The 400 USD solution consists of 6 of the devices below. They deliver 58 * 6= 348 liters of clean per second in total. 6*60 = 360 USD without sales tax.

@_mbdr_ Further thoughts, re biases: It might also be kind of dunning-kruger effect, of non-medical people DEEPLY understimating the complexity of finding a cure. They may feel that they'd find a cure for something if *they* would look at it or so. "How hard can it be?"
1/@_mbdr_ And surely, and I guess that's the elephant in the room: There will also be a lot of wishful thinking. It's just not nice to think we have a new raging virus that is actually causing (for any forseeable future) incurable permanent disease. It's tough on the conscience.
However I have seen no argument to disregard ACH's from natural ventilation, and significant natural ventilation is desirable: for low CO2. Also, a CR-box can certainly do a little more than 400 CFM, just at expense of more noise.
1/@sri_srikrishna@RanuDhillon@T_Inglesby@kprather88@AbraarKaran Total CADR from #CorsiRosenthalbox'es needed to get to 12 ACH, given known natural ventilation:
900x8 classroom:
0 ACH ➡️ 1440 CFM
1 ACH ➡️ 1320 CFM
2 ACH ➡️ 1200 CFM
6 ACH ➡️ 720 CFM
900x10 classroom:
0 ACH ➡️ 1800 CFM
1 ACH ➡️ 1650 CFM
2 ACH ➡️ 1500 CFM
4 ACH ➡️ 1200 CFM

@MeddygLou One thing that I think could make a different is increasing the hope that IF we resume masking, it won't be forever. Because I think a lot of people associate masking now with masking forever. Masking for a short while is definitely more palatable than masking forever.
1/@MeddygLou And then, how to to this?
Other than pointing at potential significant improvements in drugs and/or vacines (especially transmission-blocking nasal vaccines) it would be pointing out that filtering the virus out of indoor air also could greatly reduce infection risk.
