Author here. I fully agree with you that cheap Chinese resin should never be used in a living area, not even with my improvised ventilation. That's why I said in the first paragraph to "never use [China resin] outside a ventilated factory". That said, I now switched to using locally produced resin which is intended for dentists and is biocompatible (when hardened) and certified for indoor use and only has a class 1 warning level, telling you not to drink it or pour it down the drain. (As opposed to level 3 aerial lung damage with Anycubic resin.) It's quite expensive, but in my case that is tolerable.
And I believe this issue is not black and white. For most people who currently have no ventilation system at all, just adding something like mine will already be a huge improvement. Your article looks great and I agree that that might be even better, but it was not possible in my case:
I did not have any way to properly attach an exhaust, which is why I needed to use a solution that works with the existing window. And when I go on vacation, I need to close that window for insurance reasons. So I needed something that was easily removable, too.
Also, I sometimes work with Epoxy glue and Acrylic paint and I solder electronics and I wanted to make sure that the exhaust will cover these use-cases, too. That said, I think the best solution would be to combine your article and my window cover. I could probably connect a tube from the active coal filter port on my GKtwo directly to one of those fans. That way, it'd be sucking 25% of the airflow through the resin printer and the remaining 75% from the ambient air in the room.
And yes, I wear gloves, goggles, and respirator every time I handle resin. I thought that part was common knowledge, which is why I did not explicitly mention it.
