They're a newer version of #CorsiRosenthalBox which many parents tried to have in classrooms at the beginning of and a few years into the pandemic. Parents were willing to make them themselves and donate to classrooms but school divisions said no. Tried to get them into businesses too.

Alternatively, Google "#CorsiRosenthal" box air cleaner. It's a #DIYAirCleaner that anyone can make with an armful of supplies from Canadian Tire, & coffee. All you need are a couple of rolls of duct tape, 4x MERV-13 furnace filters, & a box fan (preferably a Lasko).

This post by @daniellebeckman.bsky.social is another reason why my spouse and I respirator mask anywhere indoors except for my own home. This is why we have #CorsiRosenthal boxes in our home and why my spouse and I haven't eaten inside a restaurant since early February 2020.

I think the problem was that they should have said upfront we don’t have enough and told the public to do their best. Open windows, build Corsirosenthal boxes but instead they told us to only wash our hands and from that point things went downhill.

Or use the old school CorsiRosenthal box. It's noisier than the newer version but very easy to build. /2

An empty room might not be empty of COVID! It can linger in the air for hours. So open the windows and ventilate. Stay masked.

once again, my health reminder from my drawn syllabi - I've been putting a version of this on \them since we returned to in-person classes. (The text syllabus says the same just with more words). New syllabus is about done - I'll post the final with my Ai statement tomorrow for all who wanted it...

Upgrading schools and medical facilities with improved ventilation systems would stop this.
It's absolutely pathetic how long this is taking to reconcile.
It's almost as if our world is being led by greed and a murderous, nazi, pedophile.

In Canada that’s been done!
You can find #CorsiRosenthal DIY kits online @donatemask.bsky.social
They sell respirator masks, Aranet C02 monitors and a plethora of other items. The best part is their charitable side, since the pandemic began, they’ve been able to provide free masks to all in need.

That seems to be the club. I've decided not to trust anyone who is not CC. If anyone comesto my house, we sit outside. I have corsirosenthal boxes running in the house and I have an old swamp cooler outside to blow cool air past us. Very few people care to understand the damage SARS2 does.

#CorsiRosenthalbox screenshot from 2020. @corsiaq.bsky.social @jimrosenthal5.bsky.social came up with the design. I also have three in my home. For some people the drawbacks of the original #CR boxes are the size and the noise level, the #CRbox 2.0 if you will, solves these issues. 1/

@cleanaircreworg.bsky.social @corsiaq.bsky.social I built this #CorsiRosenthal box with a dual computer fan last night; no extra space on the fan unit. Taped everything in. Gravity pulled the fans in. Here's what I've done, along with pictures of the gap I need to bridge. Suggestions? Thanks.

We have a #CorsiRosenthal box in the basement. They're great!!!
and a quick C-R box is another option for larger spaces.
TEACHERS and Child Care providers.. If you HAVE an air filter in your room.. it would have been nice if you kept using it but PLEASE turn it on TODAY!!

On both CBC MetroMorning and on Radio-Canada MatinToronto we are hearing warnings about air quality in Toronto due to #wildfire smoke.
On MatinToronto the recommendation is to use air cleaners indoors.
Don’t have one? Consider a trip to IKEA to get both a cleaner and an air quality sensor.
