I have been looking at these also but my concern is the fan is not strong enough to really achieve any worthwhile movement of air and fumes from the area. I live in the very far north now and will have to airbrush in the house because I do not have a basement or warm garage to use. I know if I had a hardware store available to me I would purchase a lower end stove hood and make a box for it to sit on. After that it takes a little knowledge to wire a plug into it and attach a boot and then some dryer hose to a window and ventilate it out side. The advantage of this is you get work lights if you buy the right kind and a charcoal filter with a strong fan to get rid of fumes. The disadvantage is that you will have to build it more as a permanent set up which may be an issue if you have a small area.

Buying a setup you have to remember you pay for what you get and cheaper is not always the way to go especially if you are concerned with fumes. If you can't build one then I think looking at the more expensive ones would be the right thing to do because you need a very high CFM. My uncle had an autobody shop and his fan was built into a corrugated steel drain pipe and I can tell you one thing that thing was strong and could change the pressure in the garage. now he worked with automotive paints and wore a respirator even then before all the fancy equipment they use today. The point is you have to be able to move the air through your filters and outside so you need a very strong fan to do that. For me I want to build one because I will end up spending the costs of a smaller high end one probably still with low CFM without importing it and getting a larger painting area in the end until then I guess I have to stay with a brush and do it the old way. Whatever you do in buying one please do not put your health at risk to save a couple of bucks. Lungs are hard to replace and we do have to think about the others in the house also right!

Hey Matthew,
Which furnace filters do you buy from Home Depot?
