Positive or negative pressure?

  I'm trying to find information out about positive or negative pressure paint booths I tried looking and I know I've seen it in here somewhere. can somebody point me in the right direction or send me a link to these posts. I'm not looking to build my own I plan on purchasing one so I'm not sure if they're all the same or if there's a certain one That I should look at getting.  Also what is everybody else using as far as positive and negative paint booths ? Thanks in advance.

    Negative, running positive pushes your overspray out every crevice and lands on EVERY surface in your shop...

    I prefer positive pressure eliminates sucking in debris for shop if sanding is being done when running paint booth . Doesn't need to be much positive pressure. Also when you go in and out of door air is being pushed out instead of sucked in (unless you got a exhaust shutoff switch at door)

    Just need your door by your exhaust so when you enter/exit any dust isn't pulled over your parts. As long as the booth is sealed and filtered properly, you should be sucking unfiltered air from your shop. Only through the filters.

    Yeah, typically the oldest booths we had ran positive for those same reasons. So a crappy shop ended up looking even crappier. When I installed new booths, I sealed them well. Problem solved

    Thank you all for you input. The door by the exhaust is a great idea. You guys are a life saver..
