Re: Fume-blocking Enclosure

Sorry for the delayed response! Regarding the blowers on the filter, they generate a pretty stiff breeze even with two layers of filtration. These are the blowers I purchased: http://a.co/anoGsXG. They're rated at 42CFM each. I based my filter setup off another enclosure filtration design that featured two 120mm blowers, and while I considered just buying one of these blowers, I decided not to skimp. After building this, I'm tempted to say that one blower would probably be sufficient. With my current design, I think the two blowers help maximize all surface area of the current HEPA filter I'm using, but if I started over with a different filter size, I might just design it with one blower.
Question for you: What ULPA filter are you going to get? I started looking into that as well, and that probably means a V2 of my filter design.
I'm with you when it comes to sticking with this challenge. I really want to figure out a good affordable solution to this without poisoning myself or creating bad prints. And I really don't want to have to build ventilation to the outside, but I will if I absolutely have to (thinking a removable window insert and a Shop Vac tube with a blower, but again, only if absolutely necessary).
My next step is to throw together a temperature logger (using a temp sensor I have on hand and a Sparkfun ESP8266 IoT board) so I can get an idea of the temperature fluctuation over the course of the print.
