you can build a cheap classroom scale air filter for just a few dollars clean air k 12 dot com

Definitely support more air filters in schools (and elsewhere!) but there are some reasonable critiques of that study statmodeling.stat.columbia.edu/2020/01/09/fil

i think you should be equally skeptical of charter school outcomes data

What happens if you put air filters in the charter schools too.

Not saying air quality isn't important but...

Bro, have you seen what iodine in salt did:

53. Adding iodine to salt in the US led to an 11% increase in income and increase of one standard deviation IQ. en.wikipedia.org/wiki/Iodised_s

Do you genuinely believe this study is accurate and can be replicated? Hand on heart word of honour etc do you really believe it?

Cleaner air in classrooms could be transformative for student health and academic success. The impact of poor ventilation, CO₂, and particulate matter on absenteeism and performance is well-documented. For example, increased CO₂ levels are associated with more absences

SPENCER

@SP1NS1R

Given some (varying) amount of funding from the state and fed is tied to performance, this seems like an obvious “$1 in $X out” ROI? The avg cost of a student nationally is ~$20k, which makes it even more compelling.

Not enough data presented here to say if it was actually the air filtration that improved test scores. The filtration systems being used may have had other effects such as reducing CO2 levels and increasing O2 levels, depending on their model. It doesn't take very long for a few

Russell Johnston

@RussellJohnston

Cheap air filters won't remove gas molecules - which was the original problem. Activated charcoal can, but is quite expensive. Very low standards for air circulation have led to problems with CO2 buildup all over the place (thanks to some bad science once upon a time), but

Even if true, we should care about these test scores why?

These data points are equally suspect.

Super easy hack. Still not sure why principals in every school don't do this

what is your opinion?

I’d love to see this study be replicated.

Is this about American public schools?

Make education HEPA again

Changing lightbulbs increases productivity, as well.

Looks like a prime spot for someone to actually make a difference.

Probably the ambient noise.

you get the funding for this one?

@doodlestein

They should also use those co2 monitors because I’m convinced that older schools have crazy high levels from the heating systems and it literally lowers IQ by a few points when the saturation gets above a certain level.

Hawthorne effect

I’ve realized how much air quality impacts cognition and quality of life. Hiking, being outdoors, and contrasting NYC with the countryside made it clear—clean air makes thinking so much easier.

Now swap the LED lights for natural sunlight and see what happens.

this is right up your alley

Is that only with the gas leak ie getting back to decent air quality

Wut? The author is bluffing.

From the Journal of NonReproducible Reults.

Imagine what 2 cheap filters would do, or 1 expensive one

Wrong. Correlations are not causations

no, this is not a prospective study that can draw said conclusion this shows only a correlation school that have air filters have better performance there are numerous confounding variables that would explain said correlation... the biggest being said schools have more

It's probably all the pm2.5 crap in the air that gets into the bloodstream. diesel exhaust, fertilizers, pesticides, herbicides, very fine dust, etc, etc. That stuff goes right into us.

Sight unseen, haven't even skimmed it, confidently declare it to be horseshit.

Or perhaps the gas leak improved the students outcomes?
