H/ T @healthyheating for a VERY cool study!
Robot babies, Covid, and resuspended aerosols!!
Hang onto your nappies, kiddos - it's a good old Tweetorial 🧵 with a pay to play study. So, free!
TLDR? Vacuum your carpets, and run the most air cleaning filtration you can afford

"We are perpetually surrounded by a cloud of self-induced resuspended particles, referred to as the".... Pigpen effect (my thread, my word, Pigpen).

Infants can travel up to 20 football fields during a day, with a path as crazy as a cat zigzagging through a room full of Roombas.
If we can kick up our own dust, you would think infants could. And that's what they set out to measure. twitter.com/i/web/status/1…

First Annual #CorsiRosenthalBox Awards
Selected from the over 600 replies and quote tweets for CR Boxes made in 2022. Wow! What great entries. Almost impossible to select 2022 recipients, & so I encourage the audience to just peruse 👇! Here we go! (long thread & possibly 2)

The Top 3 Awards for Best Presentation of a #CorsiRosenthalBox
Third Place goes to Chris!
This one looks like a museum piece.

Very professional look. Any army of CR Boxes ready for action.

Building more #CorsiRosenthalBoxes
Because at a price of £174, and a Clean Air Delivery Rate of 585m3 per hour on the lowest setting… a CR Box blasts most commercial air cleaners out of the water

Herewith a longish thread on how these #CorsiRosenthalBoxes helped 3 of us avoid #COVID19 while a family member self-isolated. Extra challenges included (1) a Yukon winter, and (2) controlling infectious aerosols in an energy efficient house.

I made these two C-Rs during our family's latest scrape with C19. These are my 9th and 10th DIY air cleaners. The others (save one) are in schools and a restaurant in the Yukon.

This is how it began:
Following a recent indoor event attended by hundreds of unmasked delegates in Whitehorse (many with science degrees, yes), the geologist brought home C19, in spite of trying not to.

Soon I’ll have no money left for #corsirosenthalboxes! Requests are coming in thick and fast, and soon I’m going to have to start saying “no”…

On 24th November 2022 (time stamping for future ref), the Department for Education (@educationgovuk) wrote to all their mailing list members (Local Authorities and signed-up schools). They stressed the importance of ventilation to tackle Covid and flu in schools this winter👇 2/
In this email, the DfE confirmed they are reopening their programme for FREE air cleaning units - which they endorse for classrooms where good ventilation has proven difficult to achieve. I think this is driving a renewed interest in clean air in schools

@CorsIAQ. It is not going to require rocket science to improve IAQ. We have the tools to do it now. If we do it we will get better health outcomes. We need to make sure we don't leave any community behind. We need accessible tech for IAQ.

@ShellyMBoulder We need to regulate IAQ as a public good like water (YES!!!). Once we view it as a public good the answers are there. We need standards, regulations and enforcement just like we do for water. We have the tools, we don't have framework to implement the changes.3/

(Thread) My kiddo is now in middle school, and she’s leading an elective class in building DIY air purifiers for the entire school. /1
She presented to the class last week about the importance of indoor air filtration and how to build the filters. We donated the supplies for nine #corsirosenthalboxes. We dropped them off Tuesday and the class started construction. /2
The filters will reduce the spread of covid and other viruses and will help with allergies and wildfire smoke, too. Should keep more kids healthy and in school. /3
Easter is April 17 (April 24 in Orthodox churches.) Many churches experience high attendance. Some ideas to make these gatherings safer.

Your furnace/HVAC system should have the best filters feasible, preferably MERV-13 or similar.
When building is occupied, run the fan/blower continuously, not just when the system calls for heating/cooling.
Also consider HEPA air purifiers or #CorsiRosenthalBoxes in rooms.

If your system has fresh air ventilation w outside air admitted, have it set to bring in maximum outside air.
If not, open some windows on opposite sides of the room to bring in a constant flow of fresh air.
Use a carbon dioxide meter to help evaluate building ventilation

1/ 3 hours in the late night & a seed tossed into the social media wind. Origin of the #CorsiRosenthalBox.
There were 2 motivations for the concept.
Motivation 1. Make effective air cleaning more accessible to those who cannot afford $300 HEPA air cleaners.

Motivation 1. Make effective air cleaning more accessible to those who cannot afford $300 HEPA air cleaners.
2/ Motivation 2. Help schools employ effective air cleaning at a cost that would not be prohibitive given financial constraints. In summer 2020 school districts seemed overwhelmed, confused, & vulnerable to purchasing shiny objects that might not actually be all that effective.
3/ Three criteria were considered for the device:
(1) Effective, removing a reasonable amount of virus-laden aerosol particles from indoor air.
(2) Inexpensive, much lower cost than HEPA air cleaners.
(3) Open source, not a “money maker” for anyone or any organization.

We assembled 100 Corsi-Rosenthal filter boxes.
Let’s do the math: 100 x 30 students per classroom = more than 3,000 students who will have another layer of protection when they attend school.

Every layer matters. Every layer helps reduce exposure which may save lives.
