Occasionally you may need to do some sanding or cutting of foam board using power tools. Doing that will certainly create dust. You can use a shop vac for your various power tools, but they are loud, bulky, and not easily transported from garage to basement. So if you have a handheld vacuum and a few hose accessories, you can make a relatively quiet, very portable dust collector. I used a Ryobi unit but I suspect that any brand can be adapted. I bought an extension hose and it came with extra connectors to fit various dust port sizes. I needed to make an adapter from some foam board wrapped with tape to fit onto the brush accessory. The brush itself can be easily removed from the plastic housing. I have a 5″ disc sander and a small hobby table saw that I connect to the dust collector.
