Kudos for finally showing your cards as antimaskers.
And showing us that if we too lived in Marin County, CA, we could have HEPA's in every class, 98% vaccination, and make $170,000/ year.
But we live in Birmingham, AL.
Or towns like Birmingham with people that normally would hang on to your every word.
But now, where "the staffing shortages left classrooms without teachers. Schools were without essential staff such as child nutrition workers to serve meals and custodians to clean buildings"
Lol...the ad link below is to another story, "Who's really learning? 1 in 3 Alabama students sent home."
Anyway, teachers have only 5 students showing up.
That's our normal.
Teacher union is going to go on a sick-out. Is it normal that no one will even notice?
But you know what? Parents actually support the teachers there 👇👇. Guess they are getting tired of your bullshit.
An important topic since way before 2020, but given fresh vigor with our collective interest in clean air. Not just disease free air, but VOC, PFA, microplastic, mold, UFP, PM 1, PM 2.5, etc.
The outside air will infiltrate inside.

That ☝️picture is not typical.
Typical ACH - there can be general estimates, but every house is different. You can determine your own, as shown by @jljcolorado with help 👇👇. Jump to the section shown 👇.
The thread about that article is here. Some excellent discussion on it by some very good scientists, including those Dr. Jimenez acknowledges. Those folks are also on Xitter.
1 lamp was good enough to disinfect room. Produced "negligible" ozone. -0.62 ±0.03 ppb
Even with 4x the needed strength? 6.98 ±0.24 ppb.
The conclusion? One lamp does not impact the air quality.
With 4 times OVERKILL.
Under 10 ppb. Secondary organic aerosols (SOA)? minor increases in particulate matter (16% increase particulate matter, 10 % increase in particle number count).
