From my experience printing with esun ePC (before I had a Filastruder) it doesn't really have much of a smell. If you get close to take a look at a print your eyes will start to sting, so it's clearly putting something out - you just don't really smell it and it seems to drop off fairly quickly when you move away. Personally what I like to do is put my printer on a smart electric plug, so I can kill power to it remotely, and then put one of those $60 cameras that have a motor in their base watching over the printer. If I don't like what I see I kill the print or kill power to the printer entirely (depending on what's wrong), otherwise if it's working good I'm nowhere near the printer while it's printing.
On a side note I found polycarbonate to print beautifully, very well defined features, yet I ended up having to reprint in PLA because I needed a rigid part and the polycarbonate was way too flexible for me.
Just don't open the door, then sit there between the printer and the door because then the breeze will be pulling the gas/particulate right over you on the way out.
