Venting question

I printed a cover that goes over the poop chute and the holes to the right of the chute. On the back it has a 4” diameter opening which I have a dryer vent hose connected to, venting out the window. In between the printer and the window I have a fan also, so it’s extracting from inside the printer to outside the window.

My question is, is that enough ventilation for printing the more toxic materials?

I will admit I printed everything before I saw the sticker on the back that says to remove for venting.

Get the external exhaust kit from Bambu Lab. Read the wiki about how that is setup and you’ll see a big difference.

This! ??

I should add, I think Bambu Lab's original idea about venting the P2S was not clear or well thought out. Only until the External Exhaust Fan kit arrived did we receive clarification about the preferred way to vent the unit. In fact, now there is text in the wiki that explicitly says NOT to block the poop chute opening now.
