Need Help - Enclosing Area

I will be moving my 3D printers to our garage. One is a H2D and I want to try using the laser. I did buy the purifier but still don’t feel comfortable using it indoors. We have a 3 car garage with another area in the back that basically makes it a 4 car garage and that’s where I’ll be putting my printers. We will be doing some woodworking in the front part and will have dust collection but no matter how good that is, it’s never 100%.

What would be the best way to do it enclose the printers or somehow keep them from getting too much sawdust? I have been searching around the internet but haven’t found good answers yet.
