Here's the 20" #CorsiRosenthalBox I'm working on. Fans in rectangular housings basically don't exist in the UK, so I made a cardboard shim out of the box for this circular one.

This build was a proof of concept (hence the green masking tape rather than duct tape, and the plastic sheeting still on the #MERV13 filter boards). I was testing whether the shim and the boards would support the weight of the fan. Despite being a mock up it's surprisingly rigid!

Next stage involves building it properly (including sealing those gaps at the corners; the 20" fan is actually more like 21.5" across and the boards are 19.5"), then using my anemometer to measure the flow rate of the finished box, so I can work out what size room it can filter. I'm intending this one for a local community centre where a Queer Club meets, to make their meetings safer.

A partially constructed Corsi-Rosenthal Box. This is a cube, around 20 inches per side. The bottom is just cardboard. The top is a round black plastic fan, mounted in a hole in the middle of another piece of cardboard, and held there with black duct tape. The four sides are filter boards - cardboard frames containing cloth like filter material. The boards are attached to the top and bottom with green masking tape. There are gaps at the corners because the boards are smaller than the fan's diameter.

I facilitated an online workshop for @freetechproject tonight and it's the first time we tackled technology to fight #Covid (Co2 monitors, air purifiers, #HEPA, #CorsiRosenthal boxes, #NukitTempest, etc) as well as why this is important (what Covid is, how it spreads, etc) and the small (predominantly older) group was very open to the ideas, sincerely inquisitive about the topic, interested in reducing risk, aware of inclusion issues, and sensitive to my own experiences as carer for a partner disabled by Covid. I'm also realising that people genuinely refer to "Covid" in the past tense sometimes because they wrongly associate it with government policy, while at the same time they very clearly understand that #CovidIsNotOver. My point is, keep tackling the topic, and keep giving folks the benefit of the doubt -- humans are of course good at heart and state policies, and obviously the establishment media, may very well indeed not, in fact, reflect people's actual concerns about Covid.
