🚨ACTION NEEDED TODAY🚨
We have until 5pm ET on Thurs 10/15 to tell the PTA to prioritize school indoor air quality.
It takes <5 minutes.
Here is what you do:
🧵
School decision: air purifiers vs positive pressure systems? New data from two consecutive smoke seasons shows PPS kept classrooms in the "Good" air quality band 87% of the time vs 35% for purifiers. Real schools, real pollution, real difference. airgradient.com/blog/field-p…

@KLINAIR_ID Great project building the CR Boxes! Now next step is to measure the effectiveness how fast PM goes down and avoid too high CO2 developments in the classrooms. Happy to send you one of our air quality DIY kits free of charge. airgradient.com/open-airgrad… Just PM me.
Per child, a classroom is the cheapest clean air you can buy. Household purchases of clean air tech will never reach the kids who need it most.

Poor indoor air quality in schools is a serious under-addressed problem that we know how to fix. Asthma alone costs 14m+ school days a year in the U.S. Classroom purifiers can cut absences by 10-20%.
@RenPhilanthropy fellows @davidcarel and @jessunscripted, now with Julie Horowitz and @glagoudas, have been scoping and building the Inspired Air Fund.

Clean air DIY!
Many people are interested in positive pressure systems. Let me give you an example here.
If you have a sheltered platform outside your wall, you can cut a hole in the wall and point the air outlet of the 3Pro toward that hole. This can create a positive pressure clean airflow of up to about 600 m³/h, which dilutes excessive carbon dioxide, particulate matter, bacteria, viruses, VOCs, and other substances in your home that affect your health.
The trade-off: keeping your home at a comfortable temperature will consume extra energy.
But usually, each person in a room only needs 30 m³/h of fresh air. So you can set the device to a very low level, and that way, both the noise and energy usage will be minimal.

Wow! Check this out. ⤵️
@SmartAirFilters is giving away free replacement filters to schools and nonprofits.
Share this with anyone you know who uses these devices.
Apply through the Google form: docs.google.com/forms/d/e/1F…

"Go inside" is incomplete advice. I took a CO2 monitor to a bakery. Here's what happened: inspiredair.substack.com/p/t…
Exciting initiative if you're building in biosecurity ⬇️
We are excited to open applications for a biosecurity cohort of @RenPhilanthropy's Big if True Science (BiTS) Accelerator, with support from @coeff_giving.
We want to train a new generation of biosecurity R&D leaders.

“There’s going to be a fundamental rebalancing in terms of how we think about indoor spaces," Allen says. "I think people won’t tolerate sick buildings. That era is over. Rightly so, and good riddance.”

There's a boring technology that could bring clean indoor air to even the poorest, most polluted contexts. See here for our own @davidcarel 's latest:
Positive pressure is standard in hospitals, data centers, and even some museums. They can cut fine particulate matter levels by 99%+. But very few people realize you can add just them to a room.
We think this could be a game changer for indoor air quality.

1/ Grateful for coverage in @nytimes @carlzimmer's piece on the future of clean indoor air and a new program giving buildings an "immune system." As I shared: "Kids were actually breathing much cleaner air three or four years ago." Here's the positive version:

The pandemic taught a critical lesson on the importance of clean air, especially in schools. At @RenPhilanthropy, we are designing a Clean Air for Schools Fund to catalyze investments that improve health outcomes and carry economic benefits.
Great to see @ARPA_H helping lead the way, and our own @davidcarel in @nytimes on the urgency of getting this right.
