How to build your own Corsi-Rosenthal Box - Corsi-Rosenthal Foundation

Dedicated to providing cleaner safer air for all.

Corsi-Rosenthal Foundation

btw, I converted mine to PC fans, and they are SO QUIET. My family hates the sound of fans, and they can't even tell the box I usually have on is running... keeps the AQI usually sub 10 (working harder to keep up this week though, so more like 15).

If you are not the DIY type, this kit has everything you need for a PC fan Corsi Rosenthal (from CleanAirKits), you have to also buy the filters.

Corsi Rosenthal Box | Clean Air Kits

Clean Air Kits are super efficient air purifiers built simply from banks of silent PC pressure fans and 3M Filtrete virus+allergen filters. Quiet enough to leave on always, powerful enough to protect from airborne pathogens like Flu, RSV, Strep, & Covid-19

CleanAirKits
@ai6yr I've used similar to keep PC guts clean. I put flexible dryer duct between the filter box and the PC's inlet fan. Positive air pressure from the filter keeps the dust mice out of everything and prevents fouling the power supply and heatsinks, and overheating. Disabling the ion generator, if there is one, keeps it from zapping anything to death.
@sasutina13 I should do that, the dust bunnies are getting out of control in my PC, even with the Corsi running lol.
@ai6yr I had a PC in a clean work area and it still collected them. It's as if the PC was itself a filter.
@sasutina13 yeah, I think they are essentially electrostatic dust attractors, lol.

@ai6yr @sasutina13 they even collect in PCs in class 1000 clean rooms

Ask me how I know

@ai6yr @sasutina13 however, at a VASTLY reduced rate and scale

@autolycos

Yes. Even in class 1 cleanrooms. Mostly it's that superfine, submicron dust that sticks to everything.

@ai6yr

@autolycos @ai6yr @sasutina13 how do you know?

@carstenfranke @ai6yr @sasutina13 Pfizer

Used to work in a group of their clean rooms doing mammalian cell culture

When we cleaned between campaigns, we got to clean the PC's. Cruft would accumulate, even over the course of 3 months.

I think it was worse there because the clean rooms were kept at extremely low humidities. Like a dew point around 0-5°C at the time. Helped reduce biofilm formation or something

@carstenfranke @ai6yr @sasutina13 it sure made the cleaners and water for injection dry up fast
@carstenfranke @ai6yr @sasutina13 and kept the tyvek suits way more tolerable to wear for up to 8 hours at a time

@autolycos

That sounds much nicer than 20C at 50%RH in full GoreTex--while slaving over hot wetsinks and reactors... And, hopefully, your mask kept your airways from drying out too quickly.

@carstenfranke @ai6yr

@autolycos @ai6yr @sasutina13 that sounds like a fun job! But the low dew points must have been tough. I never looked inside the PCs in the clean rooms I worked in. Should call some friends ...

@carstenfranke @ai6yr @sasutina13 considering how much of the rest of me was covered, I don't remember it being too bad.

It was 20 plus years ago now, so some of the discomforts are likely forgotten

@autolycos @ai6yr @sasutina13 I spent way too much time in factory size class 1000 / 100 clean rooms. Long walks, heavy, hot equipment. All while covered in plastic suits ... I think it was about 9 years. Fun, but exhausting.
@carstenfranke @ai6yr @sasutina13 6 months was enough for me, but with the Army Reserve stuff at the time, I was pushing 70-80 paid hours a week most weeks, so I was happy to move on to a non-clean room job after at U of Nebraska, Lincoln

@autolycos

24 years in class10,000 to class0 and everything inbetween, from cotton smocks and paper bouffant caps to full polyester bunny suits to GoreTex suits with Dryden Shields (think powered HEPA filters that clean your breath) and almost full-face reverse respirators. It was...educational...

@carstenfranke @ai6yr

@sasutina13 @autolycos @ai6yr oh my, how did you survive that? How do people in chip manufacturing survive that for years? I found it extremely taxing.

@carstenfranke

For me, it was taxing. There were frequent burnouts. But it also paid very well at the time.
