What sort of contraption is that? It looks like you found some sort of...air filter at Lowes, and have a box fan pull through it?A humidifier would create more problems compared to what little effect it would have of weighing the dust down and keeping it out of your lungs.
You can build a cheap box fan like this:
Or improve your dust collection at the individual tools. Doing both is better.
That is a homemade, cheapo, shop-air, dust filter, and it works! I removed the guard on the intake side and built a box that would hold (1) 1" cheapo filter and (1) 5" HEPA MERV 13 filter (about $28). The cheapo filter gets the big stuff and the HEPA filter gets the rest. I built two and place them where they will do me the most good. Most often one is wedged between the two sliding doors leading into the shop, blowing filtered air out into the rest of the basement.What sort of contraption is that?
