Easiest spray booth ever

After a bunch of priming and basecoating, my garage floor has a layer of black, which, grey, and silver dust everywhere, and tracking it into the house doesn't tend to increase the wife's serenity level, so I had to come up with something. Ingredients are a box fan and a furnace filter. Measure box fan and get a filter that will cover the entire intake side of it. Extra hanging over makes no difference. Set up the fan blowing away from you, stick the filter to the intake side using nothing more than air pressure (it will stay on there until you turn off the fan), and get to painting. I used it all day yesterday and there is zero dust on the floor. I'm using a cheap blue floss filter, but a pleated filter may do a better job if you're shooting mor volatile stuff at higher pressure. I was using heavily thinned acrylic at 15 psi, so there wasn't much of a cloud anyway.

Where is it blowing to? Or are you saying the filter traps all the particulates? If so, that's awesome.

Yeah, that'd be one hell of a furnace filter.

I doubt it traps everything, but it traps more than nothing and there was no overspray on the fan blades or the floor. I just aimed it out the garage door. There are furnace filters that claim to trap stuff smaller than pigment particles, but they don't fit into my single digit budget. I need to spray some lacquer, which is the usual cause of overspray on my floor, so I'll see how well it works.
