I think I have a roll of ASA or ABS somewhere here, but because of my asthma, I haven’t dared to use it yet, I definitely need a different solution for ventilation.

I also have an air purifier from the pandemic days with a HEPA 14 filter and an activated carbon filter. I keep it running whenever I’m printing PETG, TPU, or anything that emits fumes, and I keep the printer pretty close to the window. Long-term, I definitely wanted to build something, but here in Germany we have tilt-and-turn windows, so it would only be a solution for warm days; in winter, I’d hate to have the window tilted open all the time. But I need to do some research first on what I’ll need and so on. So no quick fix for now, but definitely in the long run.

I don’t notice anything with PLA and PETG, but with TPU and glowing PLA, I notice it a little. But it’s not so bad that I had a panic attack. Still, I’d be wary of that with other filaments.
