No open front spray booth will remove all the fumes from the work area. And since your head (especially the mouth and nose) are in the immediate vicinity of the spray source, I’d also recommend the proper respirator for the type paint you’re spraying.
The main advantage of a spray booth is to remove the majority of the fumes from the paint spraying operation. If left in the area, they will permiate the entire house, not a good situation if you’re married, and worse if the fumes are from a hazardous chemical.
I’ve got one of the Micro Mark steel spray booths, and they do work. Work while using a two-stage mask, and the only paint you’ll smell is the drying paint on the models themselves. Work without a mask, and you’ll think you can smell the fumes throughout the house, but you really can’t.
Knowing how badly spray paint stank up a house, I never sprayed indoors until I bought a booth last year.
(I only use water based paints like Poly Scale, so Floquil and other paints might not work as well)
The best way is to vent the spray booth exhaust to the out doors. My spray booth has a 3 speed fan and I can spray all day with no overspray or smell in my workshop. Only smell is if you are near an open paint container. If I have the fan set to ‘high’ the paint coming out of the air brush will not make it to the model, it gets pull up and exhausted out by the too powerful fan!
If you do a lot of painting (or plan on doing so) you can’t go wrong with a spray booth. I built one many years ago from a cardboard box & duct tape, using a 4" computer fan for exhaust. Hung the thing from a window of my apartment when I needed to paint. It worked but there wasn’t enough air flow from the one fan, especially when I placed a filter in front of it to prevent over-spraying outside the building.
When the cardboard began sagging from age I rebuilt the booth using 1/2" plywood. I made it a little bigger, added a work light and a second 4" fan and sealed the wood with polyurethane when finished. This one is still going strong after at least 15 years of intermittent use.
Do use a respirator when spraying though. Even with 2 fans running I still get some fumes in the garage.
If you exhaust it outdoors, and use a decent fan, no paint or fumes will get into the rest of the area. Can’t speak to the commercial models because I have always built my own.
I just bought an Artograph commercial spray booth recently and it does make a huge difference. Mine is vented to the outside of the house. No overspray, important because my wife has stuff in that room as well. [;)] Very little in the way of fumes and they dissapate almost instantly.
