Here goes UHN in Toronto (👉including the cancer hospital👈), repeating the same mistakes as always, because doing the right thing is less important for hospital admin than covering up having constantly done the wrong thing since COVID hit.

MEDICAL MASKS ARE NOT AEROSOL PPE, YOU NEED AN N95!

🤬🤡

They misuse this important discovery to trivialize infection control

Sadly prevention is possible but not mentioned, bc of 2019 normalcy bias- it's not bubbling but progress to limit cross-contaminations

Very disappointing conclusion

The aurora over Chicago is bright enough to see both color and structure with the naked eye. Pretty remarkable given the amount of light pollution! 🧪 🔭

"Bei den Erkenntnissen zu Folgeschäden einer COVID-19-Infektion stehen wir erst am Anfang

Es gibt Hinweise für teils lang andauernde Folgen an Lunge, Herzen, Nieren,Nervensystem und psychische Folgen

Gründe genug, keine Infektion zu riskieren!"

"Eine Warnung an alle,die glauben, dass COVID-19 eine harmlose, leichte Grippe ist

Wir wissen noch nicht, welche Folge-/Langzeitschäden diese Infektion auch bei jüngeren Personen verursacht

Deshalb: Vorsicht ist deutlich besser als Risiko!"

Ulrich Baumgärtner InspekteurSan Bundeswehr

"Increased use of masks by the public to prevent routine illness such as influenza, as well as offer protection for seasonal allergies, dust, and smoke. This would help maintain an active market needed to sustain manufacturing capacity."

This is why it doesn't matter if some brand of air purifiers aren't a certain class of "HEPA" by a particular rating system, other than for faithful labeling & consumer trust (looking at you, Levoit). All that matters is the independent CADR test (looking at you, Austin Air). /8

To recap, for in-room air cleaners, HEPA *IS NOT NEEDED*. What matters is the combination of filtration, fit, and airflow, to maximize the Clean Air Delivery Rate for a target particle type and size, verified by an independent laboratory test to an industry standard. /7

And in case you are wondering, good quality general ventilation filters will remove health-damaging ultrafine submicron particles too, that optical particle counters can't even detect. /6
