The filter in the X1 isn't good enough to filter much out at all really. It's more of a gimmick than a genuine filter solution. I've put mine in an out building and installed a shower fan in the wall which is connected up to a relay controlled by a Raspberry Pi. I've then got an air quality sensor that triggers it turning on.
Even that isn't close to being enough to filter it all out and I'd certainly not stay in the room for any length of time whilst it was printing.
