Particulate matter graph showing all levels of particulate matter (PM 0.1 - PM 10) are below 0.5 micrograms per cubic meter.
New graphs of particulate matter for a sensor, showing a trial of turning the air cleaners off and then back on. Gradual rise when cleaners turned off. Then dramatic fall as soon as cleaners turned on, even with windows and doors open. But took another change of closing two windows to drop it further.
Accuweather screen shot. Shows an AQI value of 90 ("Poor") and PM 2.5 and PM 10 values of 27 micrograms and 44 per cubic meter, respectively.
The Model E's Piera IPS-7100 was reporting PM 1 at 32 micrograms per cubic meter...
Detailed view of the outdoor PM breakdown. PM 1 through 10 at 32-36 micrograms per cubic meter. PM 0.3 at 6 and PM 0.1 at 0.6 ug/m^3.
Graph of particulate matter contrasting low PM values when windows are closed and the air cleaners are on. Then, spikes go up and then down when sensor is moved outdoors, three times, around 6am, 7am and 9am. After 8am and before the third spike, the sensor is left indoors and the windows are opened. The PM values rise slightly above their lowest values, but much smaller than the spikes.
indoor vs outdoor tests showing particulate matter levels, including PM2.5 and 1.0 are relatively high.
IQAir summary of air quality predictions in Toronto. Today will be moderate, tomorrow until friday will be better. Saturday onward goes back to moderate. Ozone and NO2 and SO2 are okay. PM2.5 is a little high (30.4 micrograms per cubic meter)
Graph showing spikes in VOC at 6am, 6:40 and 7:10am for a wine spillage, vinegar wipe-down and bread toasting, respectively. The general trend is a slow decay of the VOCs due to open windows refreshing the air.

Particulate matter counts for PM. PM2.5,PM5 and PM10 were all about 55 ug/m^3 ... now over 150 ug/m^3. PM0.1 was 0.84 ug/m^3 ... now it's 2.4 ug/m^3
graph from Visiblair Model E particulate matter sensor. Shows elevated PM count outdoors. Indoors it's very low due to air cleaners. Outside it is very high. Power failure knocked out readings part way through. Readings drop once sensor goes back indoors.
Two air quality sensors. Measurement of particulate matter (PM2.5) is around 10 micrograms per cubic meter (8 on one, about 14 on the other)

Indoor levels of PM2.5 should be kept as low as possible, as there is no apparent threshold for the health effects of PM2.5. It is impossible to entirely eliminate PM2.5 indoors, as among its sources are essential and everyday activities, such as cooking and cleaning, as well as infiltration from outdoor sources, over which residents have little or no control. However, any reduction in PM2.5 would be expected to result in health benefits, especially for sensitive individuals, such as those with underlying health conditions, the elderly or children.

AI Is Now an All-Purpose Study Tool These days, AI-assisted cheating is a major problem for colleges. Professors report a dramatic rise in AI-generated writing and other forms of misuse. Yet another, equally profound, change is taking place under the radar: Students are increasingly using artificial intelligence as an all-purpose study tool, recasting how they approach learning and reshaping their relationships with classmates and professors. AI in the Classroom, a new collection from The Chronicle, examines how artificial intelligence is reshaping the learning environment. This collection of articles, advice, and opinion pieces offers essential insights about the impact of generative AI in the classroom — and how instructors can best navigate the challenges ahead. Order your copy to learn: What constitutes appropriate use of AI technology in teaching and learning. How instructors can best prepare their students for an AI-infused world. What guardrails faculty should provide, given that many of their students are already using it. https://connect.chronicle.com/index.php/email/emailWebview?email=OTMxLUVLQS0yMTgAAAGicGdB4t1CXjOteBy_3T0iSUo9yyTIrKuVe7P9ZusgBsvcphFwc-ACf1xh-_p5H_ff4s6V6DlHwGeNe4mMmPqsbaDqStdcGm55lA
