Vaccination is ONE way to help protect your cardiovascular health, but it is not enough.
You must also actively PREVENT COVID infection by wearing a well-fitted respirator, using HEPA/CRbox filters & opening windows/doors.

We most definitely are amidst a COVID surge in ON now. Evidence in schools & wastewater is clear.
N95 or better, #CRbox, open windows/doors, avoid crowds, use iota-carrageenan nasal sprays.
Layers of protection must be maintained to avoid Covid infection.

We are in a massive Covid surge right now.
No one will tell you this, because they’re still trying to prop up the “Covid is over” narrative.
Every day we learn more about the harmful long term effects of repeat infections.
Get your vaccine (if you can). Wear a respirator. Clean the air.

@robwissink.bsky.social made one of the best PC fan #CRbox support videos out there. He reviews all of the materials/tools you would need to build your own PC fan #CRbox

I built this #CRbox using a @donatemask.bsky.social box fan for another teacher/classroom.
Another teacher saw me carrying it down the hall and asked me what it was, so I told her.
She said, "That's cool!"
Its so much more than that! It supports health & longevity (potential futures of many kids).

When it came time to change the filters of our full-sized #CRbox I decided to create a foamboard frame for Ikea Fornüftig filters instead. Filter replacement cost is MUCH cheaper in this design & it still works amazingly🙌🙌

It might be possible to mount a french cleat design on one side, so it could be mounted at the top of pre-existing black/white boards (there is usually a top slotted groove that the CRbox could attach to).
Just need a long enough extension to plug in.

Something like this.
Issue is school boards do not permit wall mounting at all.
May need a tall, thin stand with extended cord to plug in system (in order to elevate it)

Building one more #CRbox today, while I repurpose a donated 💻 with @xubuntu.bsky.social
The 💻 is going to a local grade 3 class at Malala Yousafzai PS to support student exploration & learning🙌

Well, finished one with the 3 PC fan airplate and it does a great job moving air!
Will glue the second one tomorrow if time.
Good coverage with current #CRboxes already for first day of school next week🙌

Been a busy morning with final classroom tidying and #CRbox building.
Trying to help reduce close-contact spread of airborne pathogens, like COVID-19, between my students.

That's heartbreaking.
The one I'm thinking about was definitely in America - Arizona iirc - but I expect there are people around the world who trusted leaders in their various countries, with painful results.
As a place that still uses masks and a CRBox, we hear the same argument often.

They are and always will be my friends. They, like most people in society, chose to listen to piss-poor government guidance re: masking and chose to believe the pandemic was over.
I tried to help them with guidance re: proper masking, avoiding busy indoor spaces, and #CRbox building...

Infections aren’t inevitable at all. At this point in time we need layered mitigations.
Vaccines
Ffp2 (N95) respirators
Good ventilation
Hepa air purifiers
Or build a crbox

We are careful to ensure we are using very low voltage #CRbox systems & uL certified plugs.
This more than satisfies and electrical safety requirements in Ontario.
Perhaps government should start governing by ensuring all public indoor spaces have cleaner air to prevent airborne pathogen spread.

School boards & gov'ts attempt to argue that #CRboxes in classrooms aren't safe.
Perhaps they should offer funding and support of in-class #CRbox construction activities to improve learning & make it even safer.
For the record, we've been using #CRboxes effectively for 3 years now without any probs.

Knowing boards were attempting to block teachers & students from using #CRboxes in schools, I decided to embed #CRbox construction into our math, language, and science curriculum in grade 6.
If #CRbox building is part of the learning, then it can't be removed from classrooms.

Its not cheap but completely necessary. Student health is tied directly to teacher health because we work closely 5 days a week in small classrooms.
Board red tape makes it VERY difficult to buy #CRbox materials, so I usually invest in them myself.

Around this time each year, I'm usually looking for sales on DPA equipment for my students. The kids love playing games, while exercising outside each day.
I also start buying #CRbox equipment too for cleaning the air in our classroom. I like to have it all running before students begin in Sept.
