More #CleanAir revolution…
Oregon Health Authority is buying 3500 *2nd* air purifiers for classrooms! Yes, that’s right. Portland already has 1 HEPA purifier in each learning space. Now they are adding 2, for spaces that need to get closer to 5-6 ACH.

2/ Let’s backtrack a bit for a history of #CleanAir in Portland Public Schools.
August 2021 (Delta wave, just prior to 2nd yr of in-person schooling): PPS receives engineering reports re: iAQ of each of their schools.
Sample of 1 school, Rosa Parks Elem: projects.oregonlive.com/coronavirus/sc…

3/ Note that Portland Public Schools *already had 1 HEPA air purifier installed* in every room, BEFORE the Aug. ‘21 engineering report. Also note the certified engineering stamps on each report.
Check out the detail in charts & ACH values with & without HEPA! ⬇️ (see Alt text)

4/ These reports were revealed & investigated further by @Oregonian in May ‘22 with a scathing article criticizing the district for not acting on these reports.
25% of Portland classrooms do not meet the 3 ACH target, even *with HEPA*; need more!

5/ In the @Oregonian article ⬆️, you can click on their interactive page to read each Portland school’s engineering report & see what your child’s classroom ACH rating is. They even summarize it for simplicity.
(In BC, no such reports were commissioned.)

6/ What did @Oregonian investigation also find?
Note that the investigation is from last May, 2022. Since then @CDCgov is recommending 5 ACH for all indoor spaces & ASHRAE is proposing 8 ACH for classrooms.
See a family’s testimonial from Rosa Parks School, Portland, OR, too.

7/ @Oregonian also interviewed several iAQ experts, including @WBahnfleth, @CorsIAQ, @jljcolorado, Mark Hernandez.
“By removing commonly worn masks, a room with two hourly air changes would need eight total air changes to offer the same protection, @CorsIAQ said.”

8/ The Oregonian investigation article also noted that good indoor air quality has advantages beyond reducing C19 transmission, such as those listed below.
Note that this is said in May, 2022, *before* the disastrous “tripledemic” fall term that hit North America, including BC.

9/ Fast forward 1 year to now, May 2023.
After much advocacy, Oregon Health Authority agrees to purchase 3500 more HEPA for Portland Public Schools, to supplement the 1 HEPA already in place, for rooms that need it.
BC doesn’t even have 1 HEPA per room!

10/ So far, Oregon (pop’n 4.2 million) has bought 18,704 HEPA purifiers for schools.
Compare this to BC’s measly 1,914 HEPA purifiers (BC pop’n 5.4 million). That’s over 12 times more HEPA in Oregon vs. BC, when pop’n is taken into account!
As for noise, there are solutions:

11/ What is it about @CDCofBC that is SO AGAINST #CleanAir?
In BC:
- HEPA only given to classrooms w/o mechanical ventilation
- zero authenticated engineering reports of airflow; no reports of ACH per classroom
- @CDCofBC even refuses HEPA donations!
Abysmal.

12/ Why is it so important that BC catch up in the #CleanAir revolution in schools?
Last fall was disastrous for kids & illnesses. Flu, RSV, C19. Authorities blamed “immunity debt”, since debunked. More & more studies point to immune harm from C19 instead.
Next school year?😬

13/ The world MUST get off the “reinfection cycle”.
Reducing transmission of viruses is key. And #CleanAir is part of that.
Portland Public Schools & Oregon Health Authority are way ahead of BC.
@Dave_Eby @adriandix @bcndp Your track record on this is shameful.

14/END
BC’s 4th in-person school year without #CleanAir protections is coming up. That’s unconscionable, knowing what we know now about iAQ in schools.
@Dave_Eby @adriandix: PROVE #bced iAQ w/ authenticated engineering reports, just like PPS.
Then fix!!
